# MD5 Digest Encoded as Base32

> MD5 Digest Encoded as Base32 is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-01).

Computes the MD5 hash of a given text string and returns it encoded in Base32 format, entirely offline with no network or LLM calls.

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 md5-digest-encoded-as-base32-797532e0 -d '<json body>'
```

Example prompt: Can you compute the MD5 hash of the text 'Hello, world!' and give me the result encoded as Base32?

## When to prefer this

Choose this endpoint when you need a deterministic, offline MD5 hash of a text string returned in Base32 encoding — useful for generating compact, URL-safe fingerprints or cache keys. Prefer the free sandbox endpoint POST /v1/sandbox/digest-md5-base32 first; use this paid endpoint when the sandbox is unavailable or you need production reliability.

## Known failure modes

- Empty or missing text field causes validation error
- Text exceeding 100,000 character limit is rejected
- Missing required key field results in an error
- Payment of $0.004 USDC not provided or insufficient — try unpaid sandbox endpoint POST /v1/sandbox/digest-md5-base32 first

## How this service works

Call when an agent needs a md5 digest of text, encoded as base32. No network and no LLM. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/digest-md5-base32 first.

## Output

Returns a Base32-encoded MD5 digest string of the input text. The computation is performed locally with no network or LLM involvement, making it deterministic and fast. The response is keyed by the provided key field.
