The internal numeric `id` from a `POST /api/v2/mentions` row is also accepted, for recent and archived mentions alike. Shape matches items in `POST /api/v2/mentions`. Query-parameter twin of `GET /api/v2/mentions/{sourceId}` — identical behaviour, but safe for ids a URL path segment cannot carry. ## OpenAPI ````yaml https://app.octolens.com/api/v2/openapi.json get /api/v2/mentions/by-id openapi: 3.1.0 info: title: Octolens API version: 2.0.0 description: >- The Octolens API lets you query mentions, manage keywords, and configure feeds programmatically. Every action available in the Octolens UI is available here. ### Authentication All v2 endpoints require an API key. Create one in **Settings > API** and pass it as `Authorization: Bearer `. Keys are scoped to the organization they were minted in; you cannot access another org's data. API keys carry a scope — `read`, `write` (implies read), or `admin` (implies write). Each endpoint documents the scope it needs via the `x-required-scope` OpenAPI extension and the scope badge in the docs surface. ### Rate limiting The v2 API is rate-limited at **500 requests per hour per organization**, across all keys for that org. The limit resets at the top of each clock hour (fixed hourly window — the counter is keyed by the UTC hour bucket, not a rolling trailing hour). Every 2xx response carries three headers so clients can pace themselves: * `X-RateLimit-Limit` — the hourly cap (500) * `X-RateLimit-Remaining` — requests left in the current window * `X-RateLimit-Reset` — Unix timestamp (seconds) when the window resets When the cap is hit, the endpoint returns **429 Rate Limited** with an additional `Retry-After` header (seconds until the next window). The response body is the standard `ErrorResponse` with `code: "RATE_LIMITED"`. ### Response timing Every response also carries a standard `Server-Timing` header with the server-side breakdown of that request — `auth` (credential verification, plan gate and rate limiting), `handler` (the endpoint's own work) and `total`, in milliseconds. Use it to tell whether a slow call was spent in the API's request pipeline, in the query behind the endpoint, or on the network in between; browsers surface it automatically in devtools. Responses rejected before the endpoint ran carry `auth` and `total` only, and an endpoint may publish extra metrics of its own alongside these three — parse the header as a list, not as a fixed triple. ### Error handling All non-2xx responses share the same `ErrorResponse` envelope: `{ error: { code, message, status, details? } }`. The `code` field is a stable `ApiErrorCode` enum — branch on it programmatically instead of parsing `message`. See the `ApiErrorCode` schema for the full catalog grouped by category. `VALIDATION_ERROR` (400) responses include a `details` array with per-field Zod issues — inspect `details[i].path` to pinpoint which input was rejected. ### Building filter bodies Endpoints that accept `simpleFilters` / `advancedFilters` (e.g. `POST /api/v2/mentions`, `PATCH /api/v2/feeds/{id}`) take a structured object that can be tricky to hand-craft. If you just have a natural-language description of what you want ("negative posts about pricing on reddit in the last week"), call `POST /api/v2/ai/filter-wizard` with that prompt and it will return a ready-to-use filter object you can pass straight through. servers: - url: https://app.octolens.com description: Production - url: http://localhost:3000 description: Local development security: - ApiKey: [] paths: /api/v2/mentions/by-id: get: tags: - Mentions summary: Get a mention (id as query parameter) description: >- Returns one mention by its stable platform-native `sourceId` (e.g. `reddit_t3_1abc234`), passed as a query parameter.

Grouped as follows: **Auth / request shape** — `UNAUTHORIZED` (401), `FORBIDDEN` (403), `RATE_LIMITED` (429), `VALIDATION_ERROR` (400 — response carries a `details` array with Zod issues), `INTERNAL_ERROR` (500). **Agency master-key org selection** — `ORGANIZATION_REQUIRED` (400 — an agency master key must pass the `x-octolens-organization-id` header to select a target workspace), `FORBIDDEN_ORGANIZATION` (403 — the requested organization does not belong to the key's agency). **Plan / quota walls** — `UPGRADE_REQUIRED` (403 — an Agents-plan wall: a cap was hit (the lifetime search allowance or the monthly mention quota), or the endpoint is not part of the Agents plan at all — on that plan only search, org/usage/auth introspection, the upgrade link and monitoring recommendations are available, and every other endpoint answers this code before validating input; the envelope carries two ADDITIVE fields alongside the standard three, `upgradeUrl` (the upgrade page) and `upgradeCommand` (`octolens upgrade`, which mints a single-use authenticated link into that page), so an agent gets an actionable next step, not just prose), `QUOTA_EXCEEDED` (402 — the monthly mention quota is exhausted on a non-Agents plan; enable flex pricing or upgrade). The search routes also send `X-Octolens-Searches-Remaining` / `X-Octolens-Mentions-Remaining` response headers on success so clients can self-throttle before either wall. **Not found (404)** — generic `NOT_FOUND` plus domain-specific variants: `FEED_NOT_FOUND`, `KEYWORD_NOT_FOUND`, `KEYWORDS_NOT_FOUND`, `POST_NOT_FOUND`, `MENTION_NOT_FOUND`, `SUMMARY_NOT_FOUND`, `SEARCH_NOT_FOUND`, `SUGGESTION_NOT_FOUND`, `COMPANY_NOT_FOUND`, `ORG_NOT_FOUND`, `SETTINGS_NOT_FOUND`, `NOTIFICATION_NOT_FOUND`, `VIEW_NOT_FOUND`, `ALERT_NOT_FOUND`. A resource id that exists but belongs to another workspace answers the SAME not-found as an unused id — existence is never leaked across tenants. **Authorization (403)** — generic `FORBIDDEN` (the caller is not permitted to perform the operation, e.g. insufficient API-key scope). There are deliberately NO per-resource 403 codes: cross-workspace access reads as the resource's 404. **Business-rule violations (400)** — `INVALID_INPUT` (semantically invalid arguments), `KEYWORD_LIMIT_EXCEEDED` (plan cap hit), `LAST_ADMIN` (refuses to remove the only admin), `ITEM_EXISTS` (duplicate), `INVALID_DOMAIN`, `INVALID_TIMEZONE`, `SLACK_NOT_CONNECTED` / `SLACK_CHANNEL_NOT_FOUND` / `SLACK_CHANNEL_REQUIRED` (Slack destination validation), `WEBHOOK_URL_INVALID` (webhook URL rejected), `NO_DESTINATIONS` / `NO_SAMPLE_MENTION` (notification test delivery preconditions), `INVALID_DESTINATION` (a destination is missing/mismatched its type-specific sub-object, or two share a type) / `DESTINATION_INDEX_OUT_OF_RANGE` (feed destination index). **Operation failures (500)** — `ENGAGE_FAILED` / `RELEVANCE_UPDATE_FAILED` carry a specific code so clients can distinguish a failed mutation from a generic `INTERNAL_ERROR`. type: string enum: - UNAUTHORIZED - FORBIDDEN - RATE_LIMITED - VALIDATION_ERROR - INTERNAL_ERROR - ORGANIZATION_REQUIRED - FORBIDDEN_ORGANIZATION - MASTER_KEY_REQUIRED - AGENCY_INACTIVE - NOT_AN_AGENCY_WORKSPACE - AGENCY_NOT_FOUND - WORKSPACE_NOT_IN_AGENCY - ANCHOR_WORKSPACE - AGENCY_WORKSPACE_LIMIT - INVITE_FANOUT_TOO_LARGE - SUPERADMIN_REMOVE_FORBIDDEN - USER_REQUIRED - FLEX_REQUIRES_CAP - FLEX_REQUIRES_BUDGET - AGENCY_BILLING_NOT_CONFIGURED - WORKSPACE_CREATE_FAILED - WORKSPACE_SETUP_FAILED - WORKSPACE_ACCESS_FAILED - UPGRADE_REQUIRED - QUOTA_EXCEEDED - NOT_FOUND - FEED_NOT_FOUND - KEYWORD_NOT_FOUND - KEYWORDS_NOT_FOUND - POST_NOT_FOUND - MENTION_NOT_FOUND - SUMMARY_NOT_FOUND - SEARCH_NOT_FOUND - SUGGESTION_NOT_FOUND - COMPANY_NOT_FOUND - ORG_NOT_FOUND - SETTINGS_NOT_FOUND - NOTIFICATION_NOT_FOUND - VIEW_NOT_FOUND - ALERT_NOT_FOUND - INVALID_INPUT - KEYWORD_LIMIT_EXCEEDED - LAST_ADMIN - ITEM_EXISTS - INVALID_DOMAIN - INVALID_TIMEZONE - SLACK_NOT_CONNECTED - SLACK_CHANNEL_NOT_FOUND - SLACK_CHANNEL_REQUIRED - WEBHOOK_URL_INVALID - NO_DESTINATIONS - NO_SAMPLE_MENTION - INVALID_DESTINATION - DESTINATION_INDEX_OUT_OF_RANGE - ENGAGE_FAILED - RELEVANCE_UPDATE_FAILED securitySchemes: ApiKey: type: http scheme: bearer description: >- Clerk API key.
