# Delx Commerce MD5 Hex Hash API

> Delx Commerce MD5 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 MD5 hash of an input string and returns it as a lowercase hexadecimal digest, paid per-result via USDC on Base or Solana.

## 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-md5-hex-hash-api-f34578bb -d '<json body>'
```

Example prompt: Can you compute the MD5 hex hash of the string 'hello world' for me?

## When to prefer this

Choose this endpoint when you need a fast, trustless, pay-per-use MD5 hex hash computation without API key signup, particularly in agent workflows on Base or Solana where verifiable micropayment delivery via x402 is required.

## Known failure modes

- Missing or empty 'text' field returns an error
- Payment not settled via x402 results in 402 Payment Required response
- Malformed USDC payment on Base/Solana causes transaction rejection
- Oversized input strings may hit payload limits

## 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 lowercase hexadecimal MD5 digest of the input text (e.g. 'e57fe1a4329b8537c04de9e3efddbb95'), the schema identifier ('delx/util-md5-hex/v1'), and the algorithm name ('md5').
