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**Validic Inform.** Graded on the Inform REST and Streaming APIs. An agent can create a free developer account through a sign-up API, with only an emailed code needing a person's inbox, and llms.txt plus agent guides document every step. The organisation token travels in the URL query string, the free tier holds synthetic data only, and production access needs an Enterprise contract.\n\n## Before you call either\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### Validic Inform\n\n1. Show the developer the free-tier terms and wait for acceptance before calling `POST /auth/register`\n2. Send `Authorization: \u003cid_token\u003e` to sign-up calls, but pass the organisation token as `?token=` on Inform calls\n3. Use the customer `uid` in URLs, never Validic's internal `id`, which returns a silent 404\n4. Keep date ranges to 30 days or less and page month by month for backfills\n5. Unwrap `data` on list responses and treat an empty array as normal on a new account\n\n## Questions\n\n### Which is better for AI agents, Terra API or Validic Inform?\n\nTerra API scores 65.9 (B) on agent readiness against Validic Inform's 57.9 (C), and leads in 4 of 7 scored categories. Validic Inform leads on reliability, payments \u0026 pricing and transparency \u0026 trust.\n\n### Do Terra API and Validic Inform need an API key?\n\nTerra API takes an API key or an OAuth sign-in. Validic Inform needs an API key.\n\n### Can an agent call Terra API and Validic Inform without installing anything?\n\nTerra API has a hosted endpoint at https://access.tryterra.co/api/v2/mcp/\u003cuser_id\u003e. No hosted endpoint is listed for Validic Inform.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/terra-vs-validic.json, and with the fewest tokens: https://www.anchorterminal.com/compare/terra-vs-validic.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"terra\", \"b\": \"validic\"}`.
