# Delx Commerce QR Payload Classifier

> Delx Commerce QR Payload Classifier is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Classifies the decoded text of a QR code or barcode payload into a typed category (e.g. URL, contact, etc.) and returns a normalized value.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-qr-payload-classifier-2cfbbb9f -d '<json body>'
```

Example prompt: I just scanned a QR code and got the raw payload 'https://delx.ai' — can you classify what kind of payload this is and give me the normalized form?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
