parse

Fetches the 402 challenge of a foreign endpoint without paying anything — no payment header, no signature, no settlement — or parses a challenge you already hold.

Fetches the 402 challenge of a foreign endpoint without paying anything — no payment header, no signature, no settlement — or parses a challenge you already hold. Returns x402_version, every accepts entry with scheme, network, resolved network name and chain id, asset, symbol, decimals and the amount both in raw units and in human form, plus the resource block and any expiry. amount_human is computed with the decimals of that token, resolved from a known-asset table or read from the chain; where decimals cannot be established it stays null and is listed in unavailable_fields rather than assuming six. parse_warnings names concrete gaps such as a missing description or missing inputSchema, a non-CAIP-2 network, a bridged instead of canonical asset, or an amount sent as a JSON number. It does not judge the service, does not pay, does not verify signatures and does not check whether the seller delivers. Answers for a URL are cached for 60 seconds; age_ms states the age of the fetched challenge.
