## Which one, for what

### Arcmira (B)

Good for: Agents answering what was said on YouTube shows and podcasts, who was mentioned or appeared where, which brands sponsor a show and how a name's mentions are trending, with timestamped source links, through one connection on a free monthly allowance.

Ahead on:
- Security & auth, 61 against 45

Also in its favour:
- Free to start without a card

Watch for: No status page, incident history or SLA was found; the terms disclaim uninterrupted service and Enterprise lists priority support without an uptime commitment

### Parallel Search and Task APIs (BB)

Good for: Agents that mix quick search with long research or enrichment jobs and want one vendor and one bill.

Ahead on:
- Reliability, 75 against 40
- Schema & documentation, 94 against 87
- Payments & pricing, 75 against 55
- Transparency & trust, 66 against 61

Also in its favour:
- Agent-ready, a grade of BB or better
- No incidents deducted, where Arcmira loses 3 points for them

Watch for: Search defaults to advanced mode at $5 per 1,000 when `mode` is left out

## Verdicts

**Arcmira.** Four code-mode tools over a documented v1 API, OAuth 2.1 with four scopes, a read-only sign-up key from two API calls and no card, and a 1,000-credit free month. No status page, SLA or security.txt, breaking v1 changes shipped in October with same-day notice, the server is at 0.10.7, and the index covers the shows Arcmira transcribes.

**Parallel Search and Task APIs.** Fast-mode search at $1 per 1,000 with 10 excerpted results, and a keyless two-tool Search MCP annotated read-only. Search defaults to advanced mode at $5 per 1,000 when `mode` is left out, and the Customer Terms allow training on inputs and outputs.

## Before you call either

### Arcmira

1. Call `arcmira_describe` once per session and write one program per question for `arcmira_execute_read`; return only the fields the answer needs, since output is cut at 12,000 characters and 3,000 per string.
2. Resolve names with `arcmira.resolve` (free) before any `about`, `by`, `entity_ids` or `channel` filter; a name in a filter fails with `id_required`. Plain keyword search needs no resolver call.
3. Check `arcmira.status()` or GET /v1/me for the plan, scopes and `usage.credits.available` before metered reads; on Free, media newer than 30 days and pages past the first fail with `freshness_requires_paid` and `pagination_gated`.
4. A Premium read of an untranscribed video starts a transcription that uses credits (300 per started 15 minutes) and may return `pending`; read the same video again later, which is never charged twice, and send `retry: true` only when the user asks.
5. Over HTTP send `Authorization: Bearer arc_sk_...`, an `Idempotency-Key` on every POST and PATCH, honour `Retry-After` on 429, and switch on `error.code`, following `unlock.url` on 402 and 403 rather than re-authenticating.
6. Use `arcmira_execute_write` only after listing the user's monitors; it creates, follows and pauses but never deletes, and a connection made before server 0.9.0 answers `insufficient_scope` until reconnected.

### Parallel Search and Task APIs

1. Pass `mode: "fast"` on every API search. Without it you pay the advanced rate. On an authenticated MCP connection, pin it with `?mode=fast`
2. Create Task runs with `max_retries=0` and check for an existing run before retrying
3. Give an `objective` plus two or three short `search_queries`. That's what ranks the excerpts
4. On 402, check available balance rather than total. Running tasks reserve credit
5. Ask for zero data retention or use the EU endpoint before sending private queries. The default terms allow training on them
6. On Decisions, check each answer's `type` before reading it. A refusal is a 200, not an error, and a predicate is a probability you threshold yourself
