How this service works
Decision procedure for agents handling x402 payments under sanctions obligations. Covers counterparty identifiability tiers (full identity, address-only, pseudonymous, hidden on private rails), list sources (OFAC SDN, EU, UN), fuzzy-match thresholds, and outputs PASS / HOLD_FOR_REVIEW / BLOCK / SCREENING_IMPOSSIBLE. Includes refusal receipt generation, append-only denial ledger, false-positive handling, re-screening cadence, and the private-rail case where the counterparty is hidden by design.
Output
A structured text document (brief) containing a concrete decision procedure for real-time sanctions screening in x402 agent payment contexts: inputs required (wallet address, jurisdiction, transaction amount, counterparty metadata), decision thresholds, pass/fail logic, and enumerated failure modes. Also includes metadata such as topic, service slug, generation timestamp, generation source (llm/reasoning/deterministic), and payment confirmation fields.
Example use cases
Sanctions gate before agent payment
“My agent is about to send a $0.002 USDC micropayment via x402 — what decision procedure should it follow to check whether the recipient wallet is on a sanctions list before proceeding?”
Compliance schema for agent merchant
“I'm building an x402 merchant service that receives micropayments from autonomous agents. Give me a blunt decision procedure for real-time sanctions screening so I know exactly what inputs to validate, what thresholds to use, and how to handle failures.”
Audit-ready sanctions logic for agent fleet
“We're running a fleet of autonomous agents that transact via x402. What's the step-by-step sanctions screening decision procedure we should implement, including all the inputs we need and the failure modes we have to handle?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/x402-agent-payment-compliance-real-time-sanction?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need an opinionated, agent-executable sanctions screening decision procedure specifically tailored to x402 micropayment flows, and free public documentation does not provide a sufficiently precise or agentic decision schema. Prefer this over generic compliance docs when you need structured inputs, thresholds, and failure modes ready to embed in agent logic.
Side effects
- Payment not completed — returns 402 with payment required headers instead of result
- topic override not recognized — procedure generated for default topic
- LLM generation failure — ok:false with error detail in result
- Rate limiting or server error — HTTP 5xx response
- Malformed query parameters — schema validation error
