# MD5 Digest of Latin1 Bytes Encoded as Base64

> MD5 Digest of Latin1 Bytes Encoded as Base64 is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-11).

Computes an MD5 hash of text interpreted as Latin-1 (ISO-8859-1) encoded bytes and returns the digest encoded as Base64.

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-of-latin1-bytes-encoded-as-base64-c93b5562 -d '<json body>'
```

Example prompt: Can you compute the MD5 hash of the text 'Héllo Wörld' treated as Latin-1 bytes and give me the result as a Base64 string?

## When to prefer this

Choose this endpoint when you specifically need an MD5 hash of text that must be interpreted as Latin-1 (ISO-8859-1) bytes rather than UTF-8, and want the result in Base64 encoding. This is critical for interoperability with legacy systems, older European software, or protocols that use ISO-8859-1 encoding semantics. If you need UTF-8 semantics, use the standard MD5 base64 endpoint instead. If cost is a concern, prefer the free sandbox variant at /v1/sandbox/digest-md5-base64-latin1 first.

## Known failure modes

- Text contains characters outside Latin-1 range (codepoints > 255) causing encoding errors
- Missing or empty 'text' field returns a validation error
- Input text exceeds 100,000 character limit
- Payment failure or insufficient USDC balance results in 402 response
- Key field missing or exceeding 512 characters

## How this service works

Call when an agent needs a md5 digest of latin1 bytes, encoded as base64. Send JSON {"text":"hello"}. Exact $0.005 USDC on Base. Try unpaid POST /v1/sandbox/digest-md5-base64-latin1 first.

## Output

Returns a Base64-encoded string representing the MD5 digest of the input text interpreted as Latin-1 (ISO-8859-1) encoded bytes. The response is a compact hash fingerprint suitable for checksumming or interoperability with systems expecting Latin-1 byte semantics.
