How this service works
Custom software, built by the person you talk to. Web apps, automation, eCommerce and AI for US businesses, with a fixed-scope first phase and code you own.
Output
Returns a JSON response containing x402 payment preflight details such as required payment amount, accepted currency, payment channel information, and any authorization metadata needed to proceed with the actual tool call.
Example use cases
Pre-call payment discovery for MCP tool
“Check the x402 payment requirements for the 'get_weather' tool on the server at https://tools.myservice.io before I actually call it — I want to know what it'll cost me in USDC first.”
Validating tool server x402 support
“Run a preflight check on the 'summarize_document' tool at the mcp-registry server to confirm it accepts x402 payments and get back the payment details I need to authorize the call.”
Agent workflow payment gating
“My agent needs to call the 'translate_text' tool on https://api.7it.co.il before it runs — do the x402 preflight with arguments {"text":"hello world","target_lang":"es"} so we can see the payment terms and decide whether to proceed.”
