> ## Documentation Index > Fetch the complete documentation index at: https://docs.arcmira.com/llms.txt > Use this file to discover all available pages before exploring further. > ## Agent Instructions > Arcmira has three API capabilities: Search (entities, mentions, appearances, commercial intelligence), Monitors (trackers plus alert delivery), and Transcripts (read, generate, correct). Community Review is the cross-surface correction layer. > Discover pages at https://docs.arcmira.com/llms.txt, then fetch the matching page's .md export. Each capability has a self-contained ' for coding agents' page; prefer it. > Auth: Authorization: Bearer arc_sk_... or x-api-key: arc_sk_... (x-api-key wins if both are sent). Never put keys in browser code. Check GET /v1/me for tier, scopes, and remaining rows before metered pulls. > Search: resolve names with GET /v1/entities/lookup and pin ent_* IDs before pulling metered rows. Only person entities have appearances. Mention and recommendation rows carry canonical numeric timestamps in start_seconds/end_seconds (integer seconds; 0 means full episode); the MM:SS string fields are deprecated. Commercial routes need Pro+ tier AND the recommendations:read scope and bill 10 rows per row. > Monitors: a tracker watches one entity; a monitor groups trackers with shared delivery (email, Slack, HMAC-signed webhooks). Create trackers with POST /v1/trackers, then attach by id: POST /v1/monitors/{id}/trackers { trackerIds: [...] }. Each fired alert occurrence debits 100 rows. Poll GET /v1/monitors/{id}/alerts?n= for recent deliveries. Send Idempotency-Key on every POST/PATCH. > Transcripts: switch on the access field (unlocked, locked, premium_pending, not_transcribed, unauthenticated). Honor Retry-After when polling POST /v1/transcriptions jobs. Corrections (POST /v1/videos/{video_id}/corrections; kinds line_edit, speaker_reassign, speaker_identify, add_person, entity_tag, segment_rewrite) cost 0 rows; anchored kinds need revision + anchor.contentHash (djb2 base-36); handle 409 (re-anchor) and 412 (expectedSeq). segment_rewrite replaces an inclusive segment range with new segments (empty replacements array deletes; timestamps repaired server-side). > Community Review is free (0 rows) and surface-typed: POST /v1/feedback with a type matching the surface you called, the reproducing query, and corrections targeting public IDs (ent_*, men_*, com_*). Nothing auto-applies. Do not send untyped notes. > Errors: switch on error.code, follow doc_url, quote X-Request-Id to support. Honor Retry-After on 429. Retries of POST/PATCH must reuse the same Idempotency-Key; replays return Idempotency-Replayed: true. # Batch compact entity cards by id > Free endpoint (0 rows). Batched compact lookups for UI hover cards: name, slug, type, image, and index counts for up to 50 raw integer entity ids per request. Merged ids resolve to their canonical entity but are returned under the requested id; unknown ids are silently dropped. The response is identical for all viewers and CDN-cacheable. ## OpenAPI ````yaml /openapi/arcmira-v1.json get /v1/entities/cards openapi: 3.1.0 info: title: Arcmira API version: 1.0.0 contact: name: Arcmira url: https://arcmira.com servers: - url: https://api.arcmira.com security: [] paths: /v1/entities/cards: get: tags: - Entities summary: Batch compact entity cards by id description: >- Free endpoint (0 rows).
