Delx QR Payload Classifier
x402
Delx QR Payload Classifier is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-20).
Classifies the decoded text of a QR or barcode payload into a semantic kind (e.g. URL, plain text) and returns a normalized form.

How this service works
Classify a decoded QR/barcode string (url/text/wifi heuristic). Call when routing decoded QR payloads without imaging. Returns kind and normalized as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
Returns a JSON object with a 'kind' field indicating the semantic type of the payload (e.g. 'url'), a 'schema' string identifying the classifier version (e.g. 'delx/util-qr-payload-classify/v1'), and a 'normalized' string containing the cleaned or standardized form of the payload value.
Example use cases
Route scanned QR codes by type
“I'm processing a batch of scanned QR codes in my pipeline — take this decoded payload 'WIFI:T:WPA;S:MyNetwork;P:secret;;' and tell me what kind of data it is so I can route it to the right handler.”
Validate QR content before display
“Before I show users what's in this QR code, I want to know if the payload 'BEGIN:VCARD\nFN:John Doe\n...' is a URL, contact card, or something else — can you classify it?”
Normalize URL from QR scan
“A customer scanned a QR sticker and the raw payload came back as 'https://DELX.AI/promo' — classify it and give me the normalized version so I can store it consistently.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/qr-payload-classify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have a decoded QR or barcode string and need to programmatically determine its semantic type (URL, text, contact, etc.) and a normalized canonical form before routing, storing, or displaying it. It is purpose-built for QR/barcode payload analysis, so prefer it over generic text classifiers when the input is specifically a scanned code payload.
Side effects
- Missing or empty 'payload' field returns a validation error
- Non-string or malformed input may result in an error response
- Very long or binary payload strings may be rejected
- Unknown or ambiguous payload types may return a generic 'unknown' kind
- Network or service errors return standard HTTP 5xx responses
