## 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 x402-toolbox-base64-encode-0447d8e2
```

Example prompt: Base64-encode the string 'Hello, World!' for me using the x402-toolbox pay-per-call utility.

## When to prefer this

Choose this endpoint when you need a simple, stateless, pay-per-call Base64 encoding utility with no signup or API key — ideal for AI agents operating autonomously with USDC micropayments on Base via x402. Best when you want a deterministic, serverless encoding function without managing credentials.

## Known failure modes

- Missing or empty input string returns an error or empty encoded result
- Invalid schema type may result in unexpected encoding behavior
- Payment failure via x402 (insufficient USDC balance) returns a 402 Payment Required response
- Network or Cloudflare Worker downtime causes 503 or timeout responses

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object with 'ok: true' and 'paid: true' confirming the micropayment succeeded, along with the Base64-encoded representation of the input string or schema provided.
