The x402 paywall settles Nevermined plan tokens, so generic x402 clients need its SDK or API to pay.\n\n**Tempo.** api.tempo.xyz accepts MPP on its anonymous endpoints, so an agent can pay per request without an account. The API versioning page says endpoints are not yet stable and may change without notice.\n\n## Before you call either\n\n### Nevermined API + MCP\n\n1. Call `quote_service` before `pay_service`; quotes cost nothing\n2. Ask the person to open the `setup_delegation` URL once; you can't mint the first key or budget yourself\n3. Branch on the error `code` and retry only when `retryable` is true\n4. Create a small, short delegation per task; cards stop at $10.00 across delegations unless the owner raises it\n5. Use `sandbox:` keys and mcp.sandbox.nevermined.app until the flow works\n\n### Tempo\n\n1. Send `Authorization: Payment` up front to pay per request; a 402 after quota carries the challenge in `WWW-Authenticate`\n2. Read `RateLimit-Remaining` and `RateLimit-Reset` rather than hardcoding the 20 or 100 a minute defaults\n3. Pass `chainId=testnet` with a sandbox key; a sandbox key sent to mainnet is ignored and the call drops to the anonymous limit\n4. Use `tempo request --dry-run` before paying an MPP endpoint to see the cost\n5. Branch on `error.code`, never on `error.message`\n\n## Other comparisons with Nevermined API + MCP or Tempo\n\n- [Crossmint API + Docs MCP vs Tempo](https://www.anchorterminal.com/compare/crossmint-vs-tempo.md)\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 Nevermined API + MCP](https://www.anchorterminal.com/compare/crossmint-vs-nevermined.md)\n- [Nevermined API + MCP vs Payman Genie MCP](https://www.anchorterminal.com/compare/nevermined-vs-payman.md)\n- [Nevermined API + MCP vs Stripe API + MCP](https://www.anchorterminal.com/compare/nevermined-vs-stripe-mcp.md)\n", "meta": { "attribution": "Anchor Terminal (https://www.anchorterminal.com)", "docs": "https://www.anchorterminal.com/docs/", "generatedAt": "2026-10-05", "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": "Nevermined API + MCP vs Tempo", "url": "" } ], "description": "Tempo has a score of 76.6 (BB) against Nevermined API + MCP's 71.1 (BB).
