## 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-content-trust-score-api-d22b9de1 -d '<json body>'
```

Example prompt: Can you run a content trust score on this message: 'Exclusive airdrop — send 1 ETH to receive 10 ETH back, limited time!' and check it against wallet 0xAbC123...?

## When to prefer this

Choose this endpoint when you need a pay-per-call, cryptonative content trust scoring signal — especially when integrating with Web3 platforms where wallet identity and content credibility intersect. Useful for compliance pipelines, DAO governance content, and crypto community moderation where traditional trust APIs lack blockchain context.

## Known failure modes

- 402 Payment Required if no valid x402 payment or API key is provided
- Empty or missing content field returns a validation error
- Invalid sender_wallet format may cause a processing error or be ignored
- Low-quality or ambiguous content may produce a low-confidence score
- Service unavailability on the Render-hosted endpoint during cold starts

## How this service works

Pay-per-call crypto, RWA, federal, SEC, Section 8/HUD housing, and compliance APIs via x402. Primary: USDC on Base (eip155:8453). Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k). MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.

## Output

Returns a trust/credibility score and associated signals for the submitted content, indicating how reliable or suspicious the text appears, potentially cross-referenced with the sender's wallet address.
