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 pocket-network-barcode-tools-fb3e563b -d '<json body>'
```

Example prompt: Can you decode all the barcodes in this image — https://example.com/shelf-photo.jpg — and tell me what each one says? Try harder mode if needed.

## When to prefer this

Choose this endpoint when you need a pay-per-use, no-account barcode service that handles decode, generate, and validate in a single API with broad format support (QR, Data Matrix, Aztec, PDF417, EAN, UPC, Code 128). Prefer it over free tier services when you need multi-code detection (up to 32 per image), SVG output, or fine-grained error correction control without setting up an API key.

## Known failure modes

- Image URL not publicly accessible or not HTTPS — returns error
- Unsupported image format or corrupt image for decode
- No barcodes detected in image — returns empty results
- Text payload exceeds 4096 character limit for generate
- Invalid width/height values outside 1–4096 range
- Unsupported format specified for generate or validate
- Payment not received — request rejected with 402
- Generated image URL expires after one hour — must regenerate

## How this service works

Decode, generate or validate barcodes and QR codes. Decode reads up to 32 codes from a public HTTPS image (QR, Data Matrix, Aztec, PDF417, EAN, UPC, Code 128 and more); generate answers a temporary HTTPS URL to a PNG or SVG, kept one hour; validate checks a payload and its check digit. POST /v1/barcode with operation. Pay per request in USDC; no account, no API key.

## Output

For decode: an array of up to 32 detected codes each with format, text value, and position. For generate: a temporary HTTPS URL to a PNG or SVG image valid for one hour. For validate: a boolean result indicating whether the payload and check digit are valid for the specified format. For formats: a list of readable and writable barcode formats.
