Genesis402 by UnyKorn (x402 pay-per-call)

Free, no payment, read-only. Lists Genesis402 endpoints with name, HTTP path, USD price, title and parameter schema, read from the rail's live /.well-known/x402 manifest (refreshed every 10 minutes). Use it to find an endpoint that has no dedicated genesis402_* tool, then pass its exact name and parameters to genesis402_call. Filter by keyword to keep the list short (e.g. "defi", "sec", "wiki"); w

Free, no payment, read-only and idempotent. Fetches one receipt by id from the rail's public receipts feed (twin.unykorn.org/receipts) to confirm that a paid call was settled and delivered. Use after any paid call, or to check a genesis402_prove receipt, using the receipt id returned with that result. It does not list or search receipts; you need the exact id. Returns the receipt exactly as publis

Without payment_signature (or a local payer) it returns the exact price
