## 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 gocreative-mdn-lookup-24a2c152
```

Example prompt: Can you look up the MDN documentation for JavaScript's Array.prototype.reduce method and give me the syntax and a quick description of what it does?

## When to prefer this

Use this endpoint when an AI agent needs to look up authoritative web development documentation from MDN — particularly for JavaScript APIs, CSS properties, HTML elements, or browser compatibility data — without requiring an API key or signup. Ideal for pay-per-call workflows where the agent only occasionally needs documentation lookups.

## Known failure modes

- Unknown or misspelled MDN identifier returns no results or an error
- MDN page unavailable or not indexed returns empty response
- Invalid or missing 'input' query parameter returns 400 error
- Payment failure via x402 protocol returns 402 error
- Rate limiting or service unavailability returns 5xx error

## How this service works

Keyless, pay-per-call compliance & regulated-data API for AI agents — OFAC wallet + sanctions/PEP + KYB screening, SEC filings, FRED economics, FDA recalls, federal awards, plus continuous monitoring. USDC on Base/Solana via x402, native MCP. No API key, no signup.

## Output

Returns MDN documentation content for the specified web technology, API, or language feature — likely including a description, syntax, usage notes, and possibly browser compatibility data.
