How this service works
x402 protocol version, chains, features, seller address
Output
Returns a JSON object containing the x402 protocol version string, a list of supported blockchain chains (e.g. Base), available features, and the seller's payment address used for micropayment routing.
Example use cases
Pre-flight API compatibility check
“Before I start making paid compute calls, can you check what x402 protocol version this API supports and whether Base chain is listed?”
Retrieve seller address for payment routing
“What is the seller wallet address for this compute API? I need it to configure my x402 payment setup.”
Discover supported features before integration
“Can you pull the version info from this compute API and tell me what features and chains it exposes so I know what I can use?”
