Prices for the Startup plan are public. Errors return only a `message` string, token scopes are set through support, and the status feed lists 13 incidents since 22 July 2026.\n\n**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.\n\n## Before you call either\n\n### Metronome\n\n1. Send an `Idempotency-Key` header on every POST and reuse it on retry. A cached error is returned for the same key, so use a new key after fixing the cause\n2. Give each usage event a stable `transaction_id`. Metronome ignores repeats for 34 days and accepts at most 100 events per `/v1/ingest` call\n3. On 429 read `X-Metronome-Rate-Limit-Type` (`client` or `customer`) and back off. Unlisted endpoints default to 8 requests a second\n4. With an agentic token, expect `403 AgenticMutationBlocked` on writes. Post the original method, path and body to `/v1/approval_requests` and show the person the `approval_url`\n5. Use a sandbox token for testing. The token alone decides whether a call reaches sandbox or production data\n\n### Stripe API + MCP\n\n1. Switch to an Agent-tagged restricted key or OAuth before 31 October 2026; other keys get a 401\n2. Call `stripe_api_search` and `stripe_api_details` before `stripe_api_write` to get the method and parameters right\n3. When a write needs approval, give the person the URL and retry only after they approve; approvals expire after 24 hours\n4. Send an `Idempotency-Key` on every create so a retry can't charge twice\n5. On 429, read `Stripe-Rate-Limited-Reason` and back off with jitter; a 429 without it is a lock timeout\n\n## Questions\n\n### Which is better for AI agents, Metronome or Stripe API + MCP?\n\nStripe API + MCP scores 82.4 (A) on agent readiness against Metronome's 69.7 (B), and leads in 5 of 7 scored categories. Metronome leads on reliability.\n\n### Do Metronome and Stripe API + MCP need an API key?\n\nMetronome needs an API key. Stripe API + MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call Metronome and Stripe API + MCP without installing anything?\n\nYes. Metronome has a hosted endpoint at https://api.metronome.com and Stripe API + MCP at https://api.stripe.com/v1.\n\n### Are Metronome and Stripe API + MCP open source?\n\nNo open-source release is listed for Metronome.
