# 54ch10 Data Encoder

> 54ch10 Data Encoder is a paid API for AI agents from 54ch10.uk, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Encodes a UTF-8 string into base64, hex, or URL format for use with the 54ch10 pre-interact brief API

## 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 54ch10-data-encoder-81fe947b
```

Example prompt: Encode the string 'hello world' to base64 using the 54ch10 encoder so I can use it in a pre-interact brief query.

## When to prefer this

Use this endpoint when you need to encode arbitrary UTF-8 data (wallet addresses, URLs, token contracts) into base64, hex, or URL format — especially as a preprocessing step before submitting queries to the 54ch10 pre-interact brief risk analysis endpoints. Not a general-purpose encoder; best used within the 54ch10 ecosystem.

## Known failure modes

- Missing required 'q' or 'format' query parameters returns a validation error
- Unsupported format enum value (not base64, hex, or url) returns an error
- Empty or null input string may return a malformed or empty encoded result
- Payment not included or insufficient USDC may trigger a 402 payment required response

## How this service works

54ch10: pre-interact URL check. Paste a link, get brief + domain + page. Taste /v1/open/free. 80 calls for $1. Wire in 30s. Analytics-only tooling. Not financial advice.

## Output

A JSON object with an 'ok' boolean, the 'tier' (x402), the 'format' used (base64, hex, or url), the 'encoded' output string, and a disclaimer noting the informational nature of the tooling.
