# Delx Commerce Fingerprint Lite

> Delx Commerce Fingerprint Lite 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).

Generates a compact 16-character SHA-256 fingerprint (hash) of an input text string for lightweight deduplication or identity checks.

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-fingerprint-lite-77843430 -d '<json body>'
```

Example prompt: Can you fingerprint this text for me so I can detect duplicates: 'The quick brown fox jumps over the lazy dog'?

## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.001 USDC), deterministic short hash of text for deduplication, caching, or lightweight content tracking — without needing full cryptographic security or collision resistance. It is ideal for agent pipelines that process high volumes of text and need no-signup, pay-per-result fingerprinting via x402 on Base or Solana.

## Known failure modes

- Missing or empty 'text' field returns an error
- Extremely long text inputs may be rejected or truncated
- Payment failure (insufficient USDC balance) results in a 402 response before processing
- Network timeout if the service is temporarily unavailable

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object containing a schema identifier ('delx/util-fingerprint-lite/v1'), the hashing algorithm used ('sha256-16'), and a 16-character hexadecimal fingerprint of the input text (e.g. '1d6334fef87552e1'). The fingerprint is deterministic — identical inputs always produce identical outputs.
