How this service works
Explore 330 pay-per-call x402 API services and 27 agent-native digital products, with Base USDC pricing, secure Polar checkout, and free discovery.
Output
Returns a JSON object containing the parsed payment URI as structured data, a list of any warnings encountered during parsing, the evidence scope indicating the data source, the service ID, and a full receipt with execution metadata including request ID, execution ID, latency, and a SHA-256 result hash.
Example use cases
Validate incoming payment link
“I just received this payment URI from a vendor: 'ethereum:0xAbCd...?value=500000&token=USDC' — can you parse it and tell me exactly what it's requesting and flag any warnings?”
Debug malformed payment URI
“My agent generated this payment URI but the checkout is failing — can you parse it and tell me if there are any issues or warnings: 'pay:0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913?amount=5000'?”
Extract payment details for audit log
“I need to log the structured details from this payment URI before I approve it — please parse 'ethereum:0xDeAdBeEf...?value=2500000&chainId=8453' and give me the broken-out fields.”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/payment_uri_parse/invokeWhen to prefer
Choose this endpoint when you need to programmatically extract structured fields from a raw payment URI string, especially in agent-native or x402 payment workflows where you need to validate or audit payment links before acting on them. It is purpose-built for the SignalHarness agent ecosystem and returns a receipt suitable for audit trails.
Side effects
- Malformed or unparseable URI returns an error status
- URI string exceeds 65536 character limit
- URI string shorter than 2 characters
- Network or payment processing errors on the x402 layer
- Unrecognized URI scheme may produce warnings rather than a clean parse
