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.\n\n**SerpApi.** Over 100 engines behind one GET URL, with `json_restrictor` field selection and `output=md`. 25 incidents on the status feed from July to 1 October 2026, including an outage across all APIs on 10 September.\n\n## Before you call either\n\n### Arcmira\n\n1. 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.\n2. 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.\n3. 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`.\n4. 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.\n5. 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.\n6. 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.\n\n### SerpApi\n\n1. Use the MCP with `Authorization: Bearer`, not the key-in-path URL the README leads with\n2. Read `serpapi://engines/\u003cengine\u003e` before calling a new engine, since `params` isn't typed\n3. Add `json_restrictor` or `output=md` to cut tokens, and `mode: compact` on the MCP\n4. A 429 means either the hourly limit or an empty balance. Check the account before retrying\n5. Repeat a search within the hour and the cached copy is free. Set `no_cache=true` only when freshness matters\n\n## Questions\n\n### Which is better for AI agents, Arcmira or SerpApi?\n\nArcmira scores 64.2 (B) on agent readiness against SerpApi's 62.5 (B), and leads in 5 of 7 scored categories. SerpApi leads on reliability and transparency \u0026 trust.\n\n### Do Arcmira and SerpApi need an API key?\n\nArcmira takes an API key or an OAuth sign-in. SerpApi needs an API key.\n\n### Can an agent call Arcmira and SerpApi without installing anything?\n\nYes. Arcmira has a hosted endpoint at https://mcp.arcmira.com/mcp and SerpApi at https://serpapi.com/search.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/arcmira-vs-serpapi.json, and with the fewest tokens: https://www.anchorterminal.com/compare/arcmira-vs-serpapi.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"arcmira\", \"b\": \"serpapi\"}`.
