## 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 scriptmasterlabs-base64-encode-api-x402-a0d495da
```

Example prompt: Can you Base64-encode the string 'Hello, World!' for me using ScriptMasterLabs' pay-per-call API?

## When to prefer this

Choose this endpoint when you need a pay-per-call, micro-priced Base64 encoding utility settled in USDC on Base via x402, especially in agentic workflows that already use the x402 payment protocol and need lightweight data transformation without managing a local encoding library.

## Known failure modes

- Missing or malformed input parameter returns an empty or error response
- Payment failure via x402 (insufficient USDC balance) blocks the request
- Service unavailability on Render's free/hobby tier (cold starts, downtime)
- Ambiguous or unspecified 'properties' schema input may yield unexpected output
- Rate limiting or network timeout on the hosted Render instance

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns a Base64-encoded representation of the input string or data provided. The response contains the encoded output that can be used directly in HTTP headers, URLs, or data transfer payloads.
