## 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 real-time-compliance-screening-timing-for-agentic-x402-payments-b2ffcf70
```

Example prompt: My unattended agent just received a 402 challenge from a Base USDC merchant — can you give me the compliance screening decision procedure to decide whether to allow, hold, or refuse the payment before settlement, given the counterparty address and that we're operating under US jurisdiction for a $0.002 transaction?

## When to prefer this

Choose this endpoint when an autonomous agent needs a concrete, actionable decision procedure for compliance screening before settling x402 micropayments — particularly when operating unattended across jurisdictions or on newer settlement rails like Arbitrum. It is more useful than generic compliance documentation because it returns a blunt allow/hold/refuse framework rather than marketing material, and it is specifically tuned for the x402 payment protocol context.

## Known failure modes

- Payment not settled — returns 402 challenge requiring USDC micropayment before content is delivered
- Missing or malformed input object — schema validation error
- Topic override parameter ignored or misinterpreted — returns default compliance screening brief
- LLM generation failure — ok:false in result with no brief field
- Service temporarily unavailable on k2so.wrong.systems — HTTP 5xx

## How this service works

Paid agent-facing brief on Real-time compliance screening timing for agentic x402 payments: when an unattended agent receives a 402 challenge, decide whether the counterparty (payee address, registry entry, merchant service) can be screened before settlement, what evidence is sufficient given amount and jurisdiction, and whether to allow, hold, or refuse. Also cover new settlement rails (Arbitrum joining Base/Solana/Robinho-0. Blunt decision procedure, not marketing.

## Output

A paid JSON response containing a 'brief' field with prose decision procedure text, a 'procedure' field, the topic, service slug, ISO-8601 generation timestamp, and generation source (llm, reasoning, or deterministic). Also includes payment metadata confirming the $0.002 USDC charge was settled.
