# AgentBIT MD5 Hash

> AgentBIT MD5 Hash is a paid API for AI agents from agentbit.app, paid per call via x402, $0.0015/call, status unknown (last checked 2026-10-22).

Computes the MD5 hash of a given input string

## Facts

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 agentbit-md5-hash-002a52ac -d '<json body>'
```

Example prompt: What's the MD5 hash of the string 'hello world'?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call MD5 hash computation without managing API keys or signing up for a service. Ideal for lightweight, one-off hash computations in agentic workflows that already use x402 micropayments. Not suitable for cryptographic security purposes (MD5 is not collision-resistant), but appropriate for checksums, deduplication keys, and legacy system compatibility.

## Known failure modes

- Missing or empty 'input' field returns a validation error
- Non-string input types may cause a 400 Bad Request
- Payment failure or insufficient USDC balance returns a 402 Payment Required
- Service downtime results in 5xx errors

## How this service works

Compute the MD5 hash (hex digest) of an input string. Fast, deterministic checksums and legacy fingerprints (not for security-sensitive hashing).

## Output

A JSON response containing the MD5 hash digest (as a lowercase hexadecimal string) of the provided input string.
