## 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 delx-commerce-base64url-encode-bab9de74 -d '<json body>'
```

Example prompt: Can you base64url-encode the text 'hello-delx' for me?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use base64url encoding without setting up your own encoding library or managing dependencies — especially useful in agent workflows where lightweight utility calls are needed on-demand and you want verifiable, metered delivery via USDC x402 payments on Base or Solana.

## Known failure modes

- Missing or empty 'text' field returns an error
- Malformed request body results in a 4xx response
- Payment failure via x402 (insufficient USDC balance or unsupported chain) blocks the call
- Network timeout on the Delx Commerce endpoint

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object containing the base64url-encoded representation of the input text (e.g. {"text":"aGVsbG8tZGVseA","schema":"delx/util-base64url-encode/v1"}). The encoded string uses the URL-safe Base64 alphabet (no padding, - and _ instead of + and /).
