How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object containing the payload 'kind' (e.g. 'url', 'vcard', 'wifi', 'sms'), a schema identifier string (e.g. 'delx/util-qr-payload-classify/v1'), and a 'normalized' form of the input payload value.
Example use cases
Retail barcode content identification
“We scanned a barcode on a product and got the payload 'BEGIN:VCARD\nFN:John Doe\nEND:VCARD' — can you tell me what type of content this represents and normalize it?”
QR code type gating in checkout flow
“I have the decoded QR string 'smsto:+15551234567:Hello' from a customer scan — classify what kind of QR payload this is so I know how to route it in our checkout app.”
Audit QR codes on printed materials
“We printed QR codes on our flyers and need to verify each one. Here's the decoded payload: 'WIFI:S:MyNetwork;T:WPA;P:password123;;' — what type is it and what's the normalized value?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/qr-payload-classify?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent has already decoded a QR code or barcode into raw text and needs to understand what type of data it represents and obtain a normalized canonical form. It is ideal for agentic pipelines that process physical QR codes and need downstream routing logic based on payload type. At $0.001 USDC per call with no signup required, it is suitable for high-volume scanning workflows.
Side effects
- Missing or empty 'payload' field returns a validation error
- Unrecognized or malformed payload may return an unknown kind with no normalized value
- Network or payment-related failures if USDC micropayment via x402 is not properly handled
- Very long or binary-encoded payloads may not classify correctly
