# Delx Commerce SHA1 Hex Hash API

> Delx Commerce SHA1 Hex Hash API 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).

Computes the SHA-1 hash of a given text string and returns it as a lowercase hexadecimal digest, paid per-result via USDC on Base or Solana.

## Facts

- Price: $0.001/call
- Payment: x402

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-sha1-hex-hash-api-3df0ee6d -d '<json body>'
```

Example prompt: Can you compute the SHA1 hex hash of the text 'hello world' for me?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call SHA-1 hex hash with no API key or signup, especially in agent workflows where on-demand micropayment via USDC (Base or Solana) is preferred over subscription-based hashing services. Ideal for lightweight deterministic hashing tasks where SHA-1 is acceptable (legacy compatibility, deduplication keys, non-security-critical fingerprinting).

## Known failure modes

- Missing or empty 'text' field returns an error response
- Payment failure via x402 results in 402 Payment Required with no hash returned
- Extremely large text inputs may be rejected or time out
- Malformed request body returns a 400 Bad Request

## 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 SHA-1 hex digest string (40 lowercase hex characters), the algorithm name ('sha1'), and a schema identifier ('delx/util-sha1-hex/v1') for verifiable result provenance.
