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**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.\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### 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## Questions\n\n### Which is better for AI agents, Metronome or Nevermined API + MCP?\n\nNevermined API + MCP scores 70.8 (BB) on agent readiness against Metronome's 69.7 (B), and leads in 3 of 7 scored categories.
