No status page, no published rate limits and no idempotency keys were found, and the OpenAPI file behind the reference is not published.\n\n**Terra API.** Graded on the Unified API and the Terra AI MCP server. A public OpenAPI 3.1 spec, llms.txt, per-user rate limits with Retry-After, and scoped admin tokens with approvals. Access starts at $499 a month with billing details at sign-up, the data API key has no scopes, and API key requests failed for 2 hours 38 minutes on 7 August 2026.\n\n## Before you call either\n\n### Medblocks\n\n1. Connect with `claude mcp add --transport http medblocks https://app.medblocks.com/mcp` and sign in, or send a workspace API key as a Bearer token from a backend\n2. Ask the person before calling `disconnect_health_system` or `delete_person`. Both are permanent\n3. Wait for the connection webhook or check connection status before reading records. Pulls run in the background after the patient approves\n4. Branch on `error.code`, not the message, and wait the `Retry-After` seconds on a 429\n5. Use a Sandbox workspace and the Synthetic Hospital (password `demopass`) for tests. Sandbox keys cannot reach production sources\n\n### Terra API\n\n1. Send dev-id and x-api-key headers on every Unified API and Terra AI call. A missing header returns 401 problem+json\n2. Keep each request window to 1,825 days or less and under 6,000 requested days per user an hour. On 429 with rule r2, wait Retry-After seconds\n3. Pass either fields or select to Terra AI tools, never both and never neither, or the call fails with a validation error\n4. Expect data by webhook after a user connects through the widget session. REST reads are for backfills and on-demand queries\n5. Use the Read only access level for the admin MCP server unless a change is needed. The MCP level can read API keys\n\n## Questions\n\n### Which is better for AI agents, Medblocks or Terra API?\n\nTerra API scores 65.9 (B) on agent readiness against Medblocks's 52.7 (D), and leads in 5 of 7 scored categories. Medblocks leads on payments \u0026 pricing.\n\n### Do Medblocks and Terra API need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Medblocks and Terra API without installing anything?\n\nYes. Medblocks has a hosted endpoint at https://app.medblocks.com/mcp and Terra API at https://access.tryterra.co/api/v2/mcp/\u003cuser_id\u003e.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/medblocks-vs-terra.json, and with the fewest tokens: https://www.anchorterminal.com/compare/medblocks-vs-terra.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"medblocks\", \"b\": \"terra\"}`.
