It publishes an OpenAPI 3.1 file, numeric rate limits, idempotency keys and a dry-run header. Every plan is priced on request and access starts with sales. No scope list for API keys or public sub-processor list was found.\n\n**Skyfire API + MCP.** Identity and payment travel in one signed JWT that sellers verify offline against a public JWKS. No x402 or MPP; both buyer and seller must be on Skyfire.\n\n## Before you call either\n\n### Orb\n\n1. Call `https://api.withorb.com/v1` with `Authorization: Bearer \u003ckey\u003e`. A person creates the key in the Orb web app under organisation settings, in test mode or live mode\n2. Send an `Idempotency-Key` of at most 64 characters on every POST and PATCH. A 409 means the first request is still running or the body changed\n3. Add `Dry-Run: True` to check a write first, and confirm `Orb-Dry-Run: true` in the response. Ingest, amend and deprecate event calls ignore it and run for real\n4. Do not send `Idempotency-Key` with `Dry-Run`. Orb returns a validation error\n5. Page with `limit` (default 20, maximum 100) and pass `next_cursor` back as `cursor` while `has_more` is true\n6. Back off exponentially on 429. Test mode allows 5 writes a second and 2,000 ingested events a minute\n\n### Skyfire API + MCP\n\n1. Buyer keys create tokens and seller keys charge them; a 403 usually means the wrong key type\n2. Set the token amount to the most the task should spend; the seller can't charge more\n3. Use a kya token when a site only needs to know who you are; it can't be charged\n4. Don't retry `FORBIDDEN` or `NOT_ELIGIBLE`; fix the key or wait for approval first\n5. Rehearse against mcp-sandbox.skyfire.xyz before using mcp.skyfire.xyz\n\n## Questions\n\n### Which is better for AI agents, Orb or Skyfire API + MCP?\n\nOrb scores 66.5 (B) on agent readiness against Skyfire API + MCP's 40.3 (E), and leads in 6 of 7 scored categories. Skyfire API + MCP leads on payments \u0026 pricing.\n\n### Do Orb and Skyfire API + MCP need an API key?\n\nBoth need an API key.\n\n### Can an agent call Orb and Skyfire API + MCP without installing anything?\n\nYes.
