# Free Asset Radar x402 Base64 Encoder/Decoder

> Free Asset Radar x402 Base64 Encoder/Decoder is a paid API for AI agents from free-asset-radar-x402.besenok2018.workers.dev, paid per call via x402, $0.0005/call, status unknown (last checked 2026-10-02).

Encodes or decodes data using Base64 encoding via a paid edge-hosted utility endpoint

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 free-asset-radar-x402-base64-encoder-decoder-f44e996f
```

Example prompt: Can you Base64-encode the string 'hello world' for me using the x402 utility endpoint?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call Base64 encode/decode operation without setting up a local library, especially in autonomous agent pipelines that already support the x402 micropayment protocol. It is best suited for lightweight one-off conversions in serverless or agent contexts where integrating a full crypto/encoding library is impractical.

## Known failure modes

- Missing or invalid input string returns an error response
- Unsupported mode value causes a processing failure
- Payment failure (x402 protocol) blocks the request if USDC is unavailable
- Cloudflare Worker cold start or edge outage causes timeout or 503
- Malformed request schema returns a validation error

## How this service works

Stable edge-hosted x402 utilities for autonomous agents.

## Output

Returns a JSON object containing the mode used ('encode' or 'decode') and the result string — either the Base64-encoded output or the original decoded string, e.g. {"mode":"encode","result":"aGVsbG8="}
