> Polyform Trade Party Screen is a paid API for AI agents from api.polyform.org, paid per call via x402, $0.2/call, status unknown (last checked 2026-10-02).

## 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 polyform-trade-party-screen-8a0aff55
```

Example prompt: Can you screen 'Huawei Technologies' as a trade party for semiconductors and tell me whether they're sanctioned or have any regulatory hits?

## When to prefer this

Use this endpoint when you need a fast, pay-per-call sanctions and regulatory screen for a specific named trade party without the overhead of an account or API key. Ideal for AI agents that need on-demand compliance verdicts during deal workflows, supplier onboarding, or export decisions. Prefer this over subscription-based compliance APIs when call volume is low or unpredictable, and when operating in a crypto-native or x402-payment environment.

## Known failure modes

- Party name not recognized or too ambiguous — returns empty or low-confidence result
- Payment not processed — 402 response requiring USDC micropayment on Base before data is returned
- Invalid query parameters — 400 error if required fields are missing or malformed
- Rate limiting or network timeout — transient 5xx errors
- Commodity type not supported — may return null or unscored regulatory fields

## How this service works

Pay-per-call data endpoints for AI agents. USDC on Base via x402. No account, no API key — one micropayment per call.

## Output

Returns a JSON object containing the party name, commodity, a sanctions verdict (e.g. CLEAR), a regulatory hit count, an overall trade verdict (e.g. CLEAR or REVIEW), and an array of flags with detail on any issues found.
