No x402 or MPP; both buyer and seller must be on Skyfire.\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### 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### 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## Other comparisons with Skyfire API + MCP or Stripe API + MCP\n\n- [Nevermined API + MCP vs Skyfire API + MCP](https://www.anchorterminal.com/compare/nevermined-vs-skyfire.md)\n- [Skyfire API + MCP vs Tempo](https://www.anchorterminal.com/compare/skyfire-vs-tempo.md)\n- [Stripe API + MCP vs Tempo](https://www.anchorterminal.com/compare/stripe-mcp-vs-tempo.md)\n- [Crossmint API + Docs MCP vs Skyfire API + MCP](https://www.anchorterminal.com/compare/crossmint-vs-skyfire.md)\n- [Crossmint API + Docs MCP vs Stripe API + MCP](https://www.anchorterminal.com/compare/crossmint-vs-stripe-mcp.md)\n- [Payman Genie MCP vs Skyfire API + MCP](https://www.anchorterminal.com/compare/payman-vs-skyfire.md)\n- [Nevermined API + MCP vs Stripe API + MCP](https://www.anchorterminal.com/compare/nevermined-vs-stripe-mcp.md)\n- [Payman Genie MCP vs Stripe API + MCP](https://www.anchorterminal.com/compare/payman-vs-stripe-mcp.md)\n", "meta": { "attribution": "Anchor Terminal (https://www.anchorterminal.com)", "docs": "https://www.anchorterminal.com/docs/", "generatedAt": "2026-10-04", "license": "CC-BY-4.0", "method": "https://www.anchorterminal.com/benchmark/", "methodology": "0.3", "openapi": "https://www.anchorterminal.com/openapi.json", "preview": false, "run": "2026-10-01", "runLabel": "October 2026 research run" }, "page": { "breadcrumbs": [ { "name": "Home", "url": "https://www.anchorterminal.com/" }, { "name": "Compare", "url": "https://www.anchorterminal.com/compare/" }, { "name": "Skyfire API + MCP vs Stripe API + MCP", "url": "" } ], "description": "Stripe API + MCP has a score of 82.4 (A) against Skyfire API + MCP's 40.6 (E).
