# MD5 Hash Generator

> MD5 Hash Generator is a paid API for AI agents from x402.outpimp.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Computes the MD5 hex digest of any input text string, returning the deterministic 32-character hexadecimal hash.

## 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 md5-hash-generator-85b1852b -d '<json body>'
```

Example prompt: Can you compute the MD5 hash of the text 'Hello, World!' and give me the hex digest?

## When to prefer this

Choose this endpoint when you need a deterministic, cryptographically computed MD5 hash that an LLM cannot reliably produce on its own. Ideal when MD5 checksums are required for data integrity, deduplication, cache key generation, or legacy system compatibility. Prefer MD5 over SHA when the downstream system specifically requires MD5 format.

## Known failure modes

- Missing 'text' field in request body returns HTTP 400
- Non-string value for 'text' field returns HTTP 400
- Empty string may be accepted and hashes to 'd41d8cd98f00b204e9800998ecf8427e'
- Payment not provided or insufficient triggers x402 payment-required response

## How this service works

MD5 hash generator API. Computes the MD5 hex digest of any text. Deterministic and instant — an LLM cannot reliably compute real cryptographic hashes on its own.

## Output

Returns a JSON object containing the 32-character lowercase hexadecimal MD5 hash of the submitted text. The result is deterministic — identical input always produces identical output. Returns HTTP 400 if the text field is missing or not a string.

## Request schema (JSON Schema)

```json
{
 "type": "object",
 "properties": {
  "text": {
   "type": "string",
