## 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:
- Schema & documentation, 87 against 55
- Agent ergonomics, 91 against 81
- Security & auth, 61 against 38
- Payments & pricing, 55 against 20
- Maintenance & community, 84 against 42

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

### DeepSeek Search and Fetch API (D)

Good for: Cheap per-request web search with model-ready summaries and an authority signal, plus page fetching, for agents already on a DeepSeek key and comfortable with data held in the PRC.

Ahead on:
- Reliability, 65 against 40

Also in its favour:
- No incidents deducted, where Arcmira loses 3 points for them

Watch for: Opened on 17 October 2026, with no service record of its own and no component for it on the status page

## 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.

**DeepSeek Search and Fetch API.** Search returns up to 50 results with a model-length summary, an authority tier and optional full text, and only successful non-empty calls are billed, at $0.75 per 1,000. It opened on 17 October 2026, with 5 requests a second per account, no OpenAPI file, no free tier, and data held in the PRC under a policy that permits training.

## 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.

### DeepSeek Search and Fetch API

1. Keep `query` to 128 characters and put filters in it as operators, such as `site:github.com lang:en after:2026-01-01`
2. Leave `need_content` false and read `summary` first, then call Fetch on the URLs you keep
3. Stay under 5 requests a second per account across all keys. On 408, 429 or 5xx wait and retry, since no Retry-After is documented
4. Don't retry a Fetch 403 or 404 unchanged. The page is blocked by policy, unreachable or has no Markdown
5. Don't send private queries or an end user's IP in `localization`. Data is stored in the PRC
