xFREE02 — on-chain intelligence, no API key
Nansen sells 54 endpoints on the Starchild marketplace as pay-per-use x402. There is no key and no signup: you sign a USDC payment per call and the gateway returns the data. Paying is the easy part — knowing what to send is the hard part, and that is what this skill carries.

1. Start with the catalog — it is free
references/catalog.json maps all 54 endpoints to price, required fields and a
request body. Reading it costs nothing. Guessing costs money.
