How this service works
An open index of the machine-to-machine (agent) economy. x402 routes: ranked discovery over the live x402 service market, every indexed service scored by real 30-day calls and paying-wallet bounds, with a receipt naming the snapshot hash and scoring revision. /economy routes, for Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004 agent registries, Solana agent registries, Base agent contracts and MCP servers (Official MCP Registry): each protocol's published figures (agent or server counts, transactions or payment events; payers and USD volume only where the source publishes them: payers for x402 and Tempo MPP, USD volume for x402 and Virtuals ACP), each with its unit, window and source; units differ, so totals are not summed. L402 and per-service MPP listings are not covered.
Output
Returns a JSON object indicating whether the queried address or name matched an OFAC SDN entry, including: match boolean, matchType (e.g. exact_address, fuzzy_name), list name and date, checkedAt timestamp, source URL, and an array of hits each containing the entity uid, name, type, associated blockchain address, similarity score, and sanctioned programs (e.g. DPRK3). Also includes a disclaimer note and index freshness in hours.
Example use cases
Pre-payment wallet sanctions check
“Before we process this crypto payment, screen the recipient address 0xAbCd1234ef5678901234abcd1234ef5678901234 against the OFAC SDN list to make sure it's not sanctioned.”
Counterparty name due diligence
“Run a sanctions check on the name 'Kim Jong Un' against the OFAC SDN list — return any matches with a similarity score above 0.85.”
DeFi protocol compliance gate
“We're onboarding a new user whose wallet is 0x1da5821544e25c636c1417ba96ade4cf6d2f9b5a — can you verify it's not on the OFAC SDN list before granting access?”
Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/sanctions/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, programmatic OFAC SDN sanctions screening of crypto addresses or entity names as part of a compliance workflow, pre-transaction check, or onboarding gate. Prefer this over manual OFAC lookups when operating in an automated agent context where you need structured JSON output with match confidence scores. Note: this covers only the OFAC SDN list — if you need multi-jurisdiction or non-SDN consolidated list coverage, look for a broader compliance API.
Side effects
- Missing both 'name' and 'address' parameters — at least one is required
- Name query shorter than 3 characters or containing non-Latin characters may return no results
- min_score below 0.5 or above 1.0 is rejected
- limit exceeds 25 hits is rejected
- Stale index if indexAgeHours is high — screening is against a snapshot, not real-time OFAC feed
- No match does not legally clear a party — only SDN list is checked, not OFAC consolidated or other countries' lists
