`generate_x402_challenge`Build a spec-compliant x402 v2 payment challenge (402 response body) from a price, wallet and network. Returns the challenge JSON, the base64 PAYMENT-REQUIRED header value, a curl test command, and free code snippets (Cloudflare Worker, Express) to return it. Free, no auth. Pre-validated: the same shape checks x402lint.js runs on existing endpoints.	Build a spec-compliant x402 v2 payment challenge (402 response body) from a price, wallet and network.

`generate_x402_challenge_full`Same as generate_x402_challenge plus 5 more framework snippets (FastAPI, Next.js, Django, Go, Rails, raw Node) and a ready /.well-known/x402.json manifest. Requires payment (USDC on Base, x402) -- NOT callable for free over MCP. Calling this tool returns the exact HTTP request to make instead; it does not run the generation itself.
