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**Linkup.** Per-call prices from $0.005, and no credit taken for errors, missing parameters or empty results. 429 covers both exhausted credit and rate limiting, with no `Retry-After`.\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### Linkup\n\n1. On 429, check the credit balance before backing off. The same code means out of credit\n2. Pass `reasoningDepth: \"S\"` to research unless you need more. The MCP default is L at $1.50\n3. Start with `depth=fast` and `outputType=searchResults`. Deep costs $0.05, ten times as much\n4. Send the key as an `Authorization: Bearer` header, not `?apiKey=` or a command-line argument\n5. Poll `linkup-get-research` with the task id. Research runs take minutes\n\n## Questions\n\n### Which is better for AI agents, Arcmira or Linkup?\n\nLinkup scores 68.9 (B) on agent readiness against Arcmira's 64.2 (B), and leads in 3 of 7 scored categories. Arcmira leads on agent ergonomics and security \u0026 auth.\n\n### Do Arcmira and Linkup need an API key?\n\nBoth take an API key or an OAuth sign-in. An agent can also pay Linkup per call over x402, with no account.\n\n### Can an agent call Arcmira and Linkup without installing anything?\n\nYes. Arcmira has a hosted endpoint at https://mcp.arcmira.com/mcp and Linkup at https://api.linkup.so/v1/search.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/arcmira-vs-linkup.json, and with the fewest tokens: https://www.anchorterminal.com/compare/arcmira-vs-linkup.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"arcmira\", \"b\": \"linkup\"}`.
