Which one, for what

Nevermined API + MCP BB

Ahead on

  • Reliability, 77 against 72
  • Schema & documentation, 88 against 80

Verdicts

Nevermined API + MCP

Fees published without a login, 1% on stablecoins, 2% on cards and 2% for the Router. The x402 paywall settles Nevermined plan tokens, so generic x402 clients need its SDK or API to pay.

Orb

Orb suits a company that bills on usage and wants one API for events, plans, credits and invoices. 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.

Before you call either

Nevermined API + MCP

  1. Call quote_service before pay_service; quotes cost nothing
  2. Ask the person to open the setup_delegation URL once; you can't mint the first key or budget yourself
  3. Branch on the error code and retry only when retryable is true
  4. Create a small, short delegation per task; cards stop at $10.00 across delegations unless the owner raises it
  5. Use sandbox: keys and mcp.sandbox.nevermined.app until the flow works

Orb

  1. Call https://api.withorb.com/v1 with Authorization: Bearer <key>. A person creates the key in the Orb web app under organisation settings, in test mode or live mode
  2. 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
  3. 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
  4. Do not send Idempotency-Key with Dry-Run. Orb returns a validation error
  5. Page with limit (default 20, maximum 100) and pass next_cursor back as cursor while has_more is true
  6. Back off exponentially on 429. Test mode allows 5 writes a second and 2,000 ingested events a minute
