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.

Payman Genie MCP

OAuth 2.1 with PKCE, two scopes, one-hour access tokens and refresh tokens rotated on every use and revoked on logout. No published pricing, status page, rate limits or changelog.

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

Payman Genie MCP

  1. Pass the person's request to ask_genie in their own words; don't pick accounts or fill payment fields
  2. On needs_approval, stop and tell the person; approval happens in their Genie account
  3. Retry only after NOTHING_RAN or BUSY, never after OUTCOME_UNKNOWN
  4. Treat done as acted, not settled; check the activity history before confirming a payment
  5. Sign-ins from bridge 0.3.x lack genie:self; log out and sign in again to use the self-service tools
