# Coinlight Data Encoding Converter

> Coinlight Data Encoding Converter is a paid API for AI agents from coinlight-app.vercel.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-29).

Converts data between UTF-8, hex, base64, and base58 encodings in a single API call.

## Facts

- Endpoint: GET https://coinlight-app.vercel.app/p/encode?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-29

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 coinlight-data-encoding-converter-5103d0c9
```

Example prompt: Can you convert the string 'hello' from UTF-8 to base58? I need it in Solana's encoding format.

## When to prefer this

Choose this endpoint when you need lightweight, stateless encoding conversion between the four formats supported (utf8, hex, base64, base58) — especially when working with Solana keys or signatures that use base58. Prefer it over local code-based solutions when operating in an agent context without access to crypto libraries, or when working within the Coinlight ecosystem alongside Solana/EVM blockchain tools.

## Known failure modes

- Invalid 'from' or 'to' encoding value (not one of utf8/hex/base64/base58) — likely 400 error
- Data string that is not valid in the declared source encoding (e.g. malformed hex or base58) — may return error or garbled output
- Missing required 'data', 'from', or 'to' query parameters — validation error
- Payment failure or expired x402 token — 402 response

## How this service works

Coinlight charges USDC per API call with the x402 protocol on Solana and Base.

## Output

Returns a JSON object containing the converted/encoded output string and a label identifying the endpoint (e.g. 'Base58 / base64 / hex encoder'). The agent receives the re-encoded form of the input data in the requested target format.
