# apex-edge Base64 Utility

> apex-edge Base64 Utility is a paid API for AI agents from apex-edge.pearceshrader.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-10).

Encodes or decodes data using Base64 via a paid x402 inference and audit 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 apex-edge-base64-utility-cff27070
```

Example prompt: Can you Base64 encode this string for me: 'Hello, World! This is my secret payload' — I need the encoded result to embed in an API header.

## When to prefer this

Choose this endpoint when you need a metered, auditable Base64 encode/decode operation in an agent pipeline that already uses the x402 micropayment protocol and requires a verifiable audit trail of utility calls. It is particularly useful in automated workflows where usage accountability and per-call billing are required, as opposed to a free local or library-based Base64 operation.

## Known failure modes

- Invalid or malformed input payload returns an error response
- Payment failure (insufficient USDC balance or x402 handshake failure) blocks the request
- Malformed Base64 string on decode may return a decoding error
- Empty input body may result in a validation error
- Network timeout on the Cloudflare Worker edge node

## How this service works

x402-paid inference + audit endpoints

## Output

A JSON object containing the Base64-encoded or decoded result of the submitted input data, returned after a successful x402 micropayment of $0.001 USDC is processed.
