No x402 or MPP; both buyer and seller must be on Skyfire.\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### 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.
