Verdicts

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.

Stripe API + MCP

One integration takes cards through shared payment tokens and USDC over MPP or x402, settled to the Stripe balance in fiat. Card payments from agents have a 0.50 USD minimum, so per-call micropayments must use stablecoins.

Before you call either

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

Stripe API + MCP

  1. Switch to an Agent-tagged restricted key or OAuth before 31 October 2026; other keys get a 401
  2. Call stripe_api_search and stripe_api_details before stripe_api_write to get the method and parameters right
  3. When a write needs approval, give the person the URL and retry only after they approve; approvals expire after 24 hours
  4. Send an Idempotency-Key on every create so a retry can't charge twice
  5. On 429, read Stripe-Rate-Limited-Reason and back off with jitter; a 429 without it is a lock timeout

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
