Verdicts

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.

Paid

Paid suits a builder who wants usage metering, credits and invoicing behind one API, with restricted and customer-bound keys, OAuth on the MCP server and a free plan that needs no card. No status page, SLA figure, API changelog or rate-limit numbers were found, both advertised OpenAPI links returned 404, and card payments need the builder's own Stripe account.

Before you call either

Nevermined API + MCP

  1. Call quote_service before pay_service; quotes cost nothing
  2. Ask the person to open the setup_delegation URL once; you can't mint the first key or budget yourself
  3. Branch on the error code and retry only when retryable is true
  4. Create a small, short delegation per task; cards stop at $10.00 across delegations unless the owner raises it
  5. Use sandbox: keys and mcp.sandbox.nevermined.app until the flow works

Paid

  1. Call https://api.agentpaid.io/api/v2 with Authorization: Bearer <key>. A person creates the first key at app.paid.ai. No programmatic signup was found
  2. Give every signal a stable idempotencyKey and resend the same key on retry. Signals without one are not deduplicated
  3. Send at most 500 signals a request. A 429 rejects the whole batch, so wait for Retry-After and resend it all
  4. Read the code field on a 429. CONCURRENCY_LIMIT_EXCEEDED carries no Retry-After and clears when an analytics query finishes
  5. Install the Python SDK as paid-python, the name in its README and pyproject.toml. The quickstart's pip install paid names a package we could not check
