## 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-acp-x402-keyword-extractor-2416b34d
```

Example prompt: Can you extract the keywords from this text: 'The SEC announced new RWA tokenization rules affecting DeFi protocols and stablecoin issuers on Base in Q3 2024'?

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call keyword extraction billed in USDC via the x402 micropayment protocol on Base, especially in crypto, RWA, SEC, or compliance document contexts where the broader ScriptMasterLabs data suite is already in use.

## Known failure modes

- Missing or empty 'properties' input returns an empty result or error
- Malformed input schema returns a 400-level error
- Payment not settled via x402 results in a 402 Payment Required response
- Service unavailable on Render free tier during cold start causes timeout
- Very short or low-information text may return few or no keywords

## 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
