How this service works
Operated by SpendPreflight: sanctions screening and allow/hold/block preflight for x402 payments.
Output
Returns a risk level (low/medium/high), a list of risk flags (e.g. 'new_domain'), domain intelligence (DNS records, registration age, registrar, registration date, errors), OFAC SDN sanctions matches for the name and address, and a disclaimer noting the data is informational only and sourced from the public OFAC SDN list as of a stated date.
Example use cases
Pre-payment sanctions check for agent
“Before my payment agent sends USDC to the vendor at domain freshgoods-market.io, wallet address 0xDEAD1234, check if they're on any sanctions list and tell me their domain risk level.”
New marketplace seller vetting
“I need to vet a new seller on my platform — their business name is 'Global Trade Co', domain is globaltrade-co.net. Can you run a SpendPreflight risk check and tell me if there are any OFAC matches or red flags like a very new domain?”
Crypto wallet compliance screening
“Before I whitelist wallet address 0xFEED5678 for recurring payments, run a sanctions screen on it and let me know if there are any OFAC hits or risk flags I should know about.”
Technical details
Endpoint
GEThttps://api.spendpreflight.com/v1/check?utm_source=zero.xyzWhen to prefer
Use SpendPreflight when an AI agent is about to execute an x402 crypto payment and needs a fast, low-cost ($0.01 USDC) pre-authorization risk check combining OFAC sanctions screening with domain intelligence. Prefer this over manual compliance checks or heavier KYC pipelines when you need a lightweight, programmatic preflight gate for autonomous payment agents. Best suited for scenarios where speed and cost-efficiency matter more than a full legal compliance certification.
Side effects
- Missing required query parameters returns an error — at least one of name, domain, or address should be provided
- Invalid or malformed wallet address may return null for address_match rather than an error
- Newly registered domains may show limited registrar data
- Sanctions data is only as current as the data_as_of timestamp; stale data is not flagged by the API
- Network or service unavailability returns a non-200 status with no risk assessment
