Add a per-account view of external (third-party paid) channel token usage and
quota spend, complementing the existing aggregate usage logs which mix internal
and external channels together.
Background: operators running a New-API gateway with both self-hosted models
(e.g. local vLLM) and third-party paid channels (e.g. gcable, sensenova) need
to know how much of each account's spend went to external providers, for billing
and cost allocation. The existing logs page aggregates everything; this change
lets admins classify channels as external / internal (via the existing channels.tag column, already clickable in the Channels page) and then view
per-user external usage on a dedicated page.
Changes
Backend
model/log.go: add ExternalBillingRow struct and SumExternalByUser(startTimestamp, endTimestamp, username)
Aggregates logs joined to channels where channels.tag = 'external',
covering all consume (type = 2) rows on those channels, including ratio-billed models without an explicit per-call price (the previous price-map restriction silently dropped them).
Groups by username, returning prompt_tokens, completion_tokens, total_tokens, quota, model_count.
controller/log.go: add GetExternalBillingStat (AdminAuth, all users,
optional username filter) and GetExternalBillingSelfStat (UserAuth, caller's own).
router/api-router.go: add GET /api/log/stat/external and GET /api/log/self/stat/external.
Frontend (web/src)
features/external-billing/: new feature folder with api.ts
(QUOTA_PER_USD = 500000 used for USD display).
routes/_authenticated/external-billing/index.tsx: new page
Filters: All time / Last 30 days / Last 7 days / Custom date range;
admin can additionally filter by username.
Menu entries: Admin → "External Billing" (all users); Personal → "My External Usage" (self).
features/channels/components/channels-columns.tsx: make the channel tag
column clickable for external / internal values — a one-click toggle
(updateChannel(id, { tag })) that reclassifies a channel and immediately
affects the billing page. Implemented as a small ExternalTagToggle component.
hooks/use-sidebar-data.ts: add the two menu entries (icon: Receipt).
i18n/locales/{zh,en}.json: add translation keys inside the translation namespace.
Design notes
Classification lives in channels.tag (external / internal); it is a
config, not inferred from base_url, so operators can reclassify freely in the UI.
Coverage: all models on external channels are counted. Per-request quota is already computed by the billing pipeline (per-call prices and token ratios alike), so the page reports the full money-equivalent spend on external channels without re-implementing pricing.
Amount shown as USD via quota / 500000 (New-API's default quota-per-USD).
Testing
bun run typecheck (tsgo -b): passes with 0 errors. (This is the frontend gate
enforced in the repo CI.)
go build: passes.
Runtime verified on a production deployment (v1.0.0-rc.26 + this change):
/api/log/stat/external returns 401 without a session (route registered,
AdminAuth enforced) and 200 for admin session.
Added external billing reports for administrators and personal usage reports for individual accounts, with token usage, estimated spend, account totals, and model counts.
View reports for all time, recent periods, or custom date ranges; administrators can also filter by username.
Added navigation to billing reports and controls for switching channel classifications between external and internal.
Added English and Chinese translations for external billing.
Bug Fixes
Preserved per-request charges for priced models when upstream usage data is missing or zero.
Update (round 2 review fixes): date-range inputs are parsed as local calendar dates; success:false responses surface as query errors; malformed timestamp query params are rejected as client errors; the sidebar personal entry (/external-billing?view=self) forces the self-scoped request for admins; the page description now matches the all-models totals.

Walkthrough
Adds external-channel usage aggregation and reporting for admins and authenticated users. Adds controls to switch channel tags between external and internal. Changes two non-billable usage conditions for UsePrice models.
Changes
External billing
Layer / File(s)
Summary
Billing aggregation and validation model/log.go, model/external_self_stat_empty_test.go
The backend aggregates external-channel consumption by user. Tests cover totals, filters, time bounds, and empty results.
Billing endpoints and access rules controller/log.go, router/api-router.go, middleware/access_token_routes.go
Admin and self-service endpoints parse timestamp bounds and return billing statistics. Access-token routes require log:read or usage:read.
The frontend fetches billing data, provides date and username filters, and displays usage metrics. It registers the authenticated page, navigation entries, and translations.
External channel tag control web/src/features/channels/components/channels-columns.tsx
The channel table toggles persisted channels tagged external or internal. Successful updates invalidate channel and external-billing queries.
Price-based quota handling
Layer / File(s)
Summary
UsePrice quota conditions service/text_quota.go
The zero-usage quota reset and no-usage message and error log now apply only when UsePrice is disabled.

Merge Risk: Minimal · previous review 59282
The previously reported billing and route issues are addressed at the current head. No actionable merge-blocking risk remains after normal checks.
Security architecture risk: Moderate · up to d79d7
Access to other users’ billing data remains restricted, but the new reports can change past totals when a channel is reclassified. The page also describes a narrower set of charges than the backend counts, and custom dates can select the wrong local days.
Retained concerns
Medium · security · inferred: Reclassifying a channel changes which of its past consume logs appear in external billing reports. This makes reported historical allocation depend on current configuration rather than classification at consumption time.
Medium · security · observed: The billing page says models without configured prices are excluded, but the new aggregation applies no price-map filter. Readers may treat totals that include ratio-billed models as if those models were excluded.
Low · reliability · inferred: Custom date-only ranges use UTC midnight, not the selected local days. For users outside UTC, reports can assign usage near a day boundary to the wrong billing period.
Security review details
Security Blast Radius
inferred — A permitted channel reclassification can alter historical external-billing totals for every account with consume logs on that channel; the admin report spans accounts, while the self report is scoped to one authenticated username.
Security Findings and Attack Paths
inferred — The supported integrity risk is alteration or misinterpretation of billing reports through channel classification and stated price scope, not a demonstrated nonadmin path to another account’s data or a verified debit bypass.
Trust Boundaries and Controls
observed — The all-user billing route has an admin guard; the self route has a user guard and derives its lookup identity from authenticated context. Request-supplied username controls only the admin handler.
Resilience and Maintainability Implications
observed — The normal billing-session path tracks settlement state, whereas the pre-existing no-session fallback reapplies a nonzero delta if called repeatedly. Repository-local evidence does not establish repeated fallback calls introduced by this PR.
Hardening Proposals
proposed — For billing-grade historical reports, preserve consumption-time classification or version channel classification by effective time, and make the displayed price-scope statement match the chosen aggregation contract.
proposed — Convert selected calendar dates using an explicit reporting timezone before sending timestamp bounds.

🟡 Minor · Handle success: false responses as query errors. · api.ts:27-48
common.ApiError can return an HTTP-success response with success: false. Both external billing helpers return this payload without rejecting. The page then converts the missing or empty data field to [] and displays “No external usage” because query.isError remains false.
Update the shared response handling or these helpers so a success: false response rejects before the page derives rows. The previously published page correction only distinguishes query errors from zero usage; it does not fix this response boundary.

Reject invalid timestamp filters in both handlers.
When either timestamp cannot be parsed, the ignored error leaves its value at zero. SumExternalByUser treats zero as an open bound, so a malformed filter returns broader billing totals. Validate both parameters here and at Lines 177–178. Return a client error for a malformed value.

Return an empty result when no external usage matches.
When no channel is tagged external, this branch returns a zero-valued row. Line 323 of controller/log.go then sends one row, so the page shows an account with zero totals instead of its “No external usage in this range” state. The aggregate has the same result when channels exist but no consume logs match. Return no row for either case, and have the controller return an empty array while preserving the array response contract. (raw.githubusercontent.com)

SumExternalSelfStat returns (nil, nil) when no log matched, detected via a new count(*) matched_logs sentinel. A bare aggregate always yields one zeroed row even with no match, so zeroed counters cannot distinguish "no usage" from a genuine zero-quota call (free / locally hosted model); counting matching rows is the only reliable discriminator.
ExternalBillingRow.MatchedLogs is tagged json:"-", so the API payload shape is unchanged (matched_logs never appears in the JSON).
The handler keeps the array contract: a nil row produces {"success":true,"data":[]}, so the page renders its "No external usage in this range" state instead of a phantom zeroed account.
The admin path (SumExternalByUser) is untouched: it still groups by username and returns a slice.
7 unit tests were added in model/external_self_stat_empty_test.go, including TestSumExternalSelfStatZeroQuotaIsRealUsage which pins the exact trap that rules out a "row is all zeros => no usage" shortcut. Verified against the live production DB: user with no external usage yields [], a user with usage yields 1 row whose totals match a direct SQL aggregate, and user_id scoping still prevents cross-account leaks.

Add a per-account view of external (third-party paid) channel token usage
and quota spend, complementing the existing aggregate usage logs which mix
internal and external channels together.
Background: operators running a New-API gateway with both self-hosted
models and third-party paid channels need to know how much of each
account's spend went to external providers, for billing and cost
allocation. Admins classify channels as external/internal via the
existing channels.tag column, then view per-user external usage on a
dedicated page.
Backend:
- model/log.go: add ExternalBillingRow and SumExternalByUser(), which
aggregates consume-type logs joined to channels tagged 'external',
covering all models on external channels (including ratio-billed
models without an explicit per-call price, which the previous
price-map restriction silently dropped). Resolves channel ids against
the primary DB to avoid cross-DB JOIN issues when LOG_DB is separate.
- controller/log.go: expose GET /api/log/stat/external (admin) and
/api/log/self/stat/external (self) with start/end timestamp and
username filters; malformed timestamp values are rejected as client
errors instead of silently becoming open bounds.
- service/text_quota.go: keep per-call priced quota accounting correct
when upstream usage is missing (do not zero used_quota).
Frontend:
- web external-billing page: per-user external usage table with date
range filter, accessible form labels, and error-state handling.
Date-range inputs are parsed as local calendar dates (not UTC), the
end bound includes the whole selected local day, and API responses
with success:false are surfaced as query errors.
- The sidebar offers an admin-wide entry and a personal entry
(/external-billing?view=self); admins entering via the personal entry
see only their own usage.
- channels page: external tag toggle with failure feedback, status
badge not copyable.
- i18n: en/zh keys for the new page.
- add explicit return types to ExternalTagToggle, buildParams and
ExternalBillingPage per web coding guidelines
- move the hard-coded QUOTA_PER_USD constant behind the
VITE_QUOTA_PER_USD env var (falls back to 500000) so the deployed
frontend stays in sync with the backend quota conversion
- invalidate the external-billing query after a channel tag change so
cached report totals cannot outlive a reclassification
- only derive displayed rows from a successful query so stale data is
not shown next to a refetch error
CodeRabbit Major (Security & Privacy): GetExternalBillingSelfStat previously filtered/grouped logs.username via c.GetString(username). Since users can rename their username (UpdateUser/EditWithTx), a rename drops the new name's history and a reused old name leaks the previous holder's rows. Switch the self endpoint to the authenticated user ID (c.GetInt(id)) and aggregate on logs.user_id; keep username filtering/grouping for the admin endpoint. New model.SumExternalSelfStat; response keeps the array contract for the frontend.
… username after scan
TestAccessTokenRouteRulesCoverEveryDashboardRoute requires every dashboard route to have exactly one access token scope rule, so the two external-billing routes failed upstream CI with ACCESS_TOKEN_ROUTE_UNDECLARED: GET /api/log/stat/external needs log:read (mirrors /api/log/stat) and GET /api/log/self/stat/external needs usage:read (mirrors /api/log/self/stat).
Also restore the display username after the GORM aggregate Scan, which only populates selected columns and zeroes the rest, leaving the self endpoint with an empty username.
A bare aggregate query always yields one row with zeroed counters even when no
log matched, so the self-service endpoint reported a phantom account with no
usage instead of letting the page show its empty state. Counting matched rows
is the only reliable discriminator: a genuine zero-quota call (free or locally
hosted model) also has all-zero counters and must still be listed.
- model: add ExternalBillingRow.MatchedLogs (json:/-/, never serialised),
select count(*) matched_logs, and return (nil, nil) when nothing matched or
when no channel carries tag=external
- controller: keep the array contract, emitting {"data":[]} for a nil row
- test: cover no-usage, no-external-channels, zero-quota-is-real-usage,
aggregation, user_id scoping and time windows (7 cases)
The branch was rebased onto the latest main (e449cc700) to clear the "out of date" state. The rebase was conflict-free and the diff is byte-for-byte identical to the previously reviewed commit — verified via MD5 of the changed Go files:
model/log.go — unchanged from 5928240ffc
controller/log.go — unchanged from 5928240ffc
model/external_self_stat_empty_test.go — unchanged from 5928240ffc
Upstream's 9 new commits did not touch model/log.go or controller/log.go, so this is a pure replay on a newer base. behind_by is now 0.
For reference, the empty-usage fix (from the earlier review) is still in place:
SumExternalSelfStat returns (nil, nil) when no consume log matched — detected with a count(*) matched_logs sentinel, because a bare aggregate always yields one zeroed row regardless of matches.
ExternalBillingRow.MatchedLogs carries json:"-", so the payload shape is unchanged.
The handler emits {"success":true,"data":[]}, preserving the array contract.

[PR 描述] feat(usage): add per-user external channel billing statistics
Summary
Add a per-account view of external (third-party paid) channel token usage and
quota spend, complementing the existing aggregate usage logs which mix internal
and external channels together.
Background: operators running a New-API gateway with both self-hosted models
(e.g. local vLLM) and third-party paid channels (e.g. gcable, sensenova) need
to know how much of each account's spend went to external providers, for billing
and cost allocation. The existing
logspage aggregates everything; this changelets admins classify channels as
external/internal(via the existingchannels.tagcolumn, already clickable in the Channels page) and then viewper-user external usage on a dedicated page.

Summary by CodeRabbit
Update (round 2 review fixes): date-range inputs are parsed as local calendar dates;
success:falseresponses surface as query errors; malformed timestamp query params are rejected as client errors; the sidebar personal entry (/external-billing?view=self) forces the self-scoped request for admins; the page description now matches the all-models totals.
