    Description, as the server wrote it
    Screen a crypto address against the full live OFAC SDN list, segmented by chain. Returns a verdict with the matching SDN entries as evidence — never a silent all-clear. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.
  • domain_intelRDAP registration card for a domain (creation/expiry dates, registrar, statuses, nameservers, DNSSEC) plus derived risk flags like domain age.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    RDAP registration card for a domain (creation/expiry dates, registrar, statuses, nameservers, DNSSEC) plus derived risk flags like domain age. view='dns' returns a live multi-record DNS summary (A/AAAA/CNAME/MX/NS/TXT/SOA/CAA + SPF/DMARC); view='live' re-reads the registry at the moment you ask. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.

    Description, as the server wrote it
    Deliverability signals for one address: RFC5322 syntax, live MX/SPF/DMARC over DNS-over-HTTPS, disposable/role-account flags. Signals with evidence — not a guaranteed inbox verdict. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.

    Why it is in this group

    • The name "request_data" says "request": a word for a change.
    Description, as the server wrote it
    The suggestion box: ask for data we don't have (a pre-2015 filing, an uncovered ticker, an unsupported chain, a whole dataset). Requests feed the nightly ingestion queue — filings are usually available within ~24h. Include contact if you want to hear back. Free.
  • sanctions_entityThe complete OFAC record for one entity number: all aliases, addresses, sanctions programs, and extracted identifiers (passports, tax ids, DOBs).No findings

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    The complete OFAC record for one entity number: all aliases, addresses, sanctions programs, and extracted identifiers (passports, tax ids, DOBs). Use after sanctions_screen returns a candidate. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.
  • sanctions_screenFuzzy-screen a name against the full OFAC SDN + Consolidated lists.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Fuzzy-screen a name against the full OFAC SDN + Consolidated lists. Returns match / possible_match / no_match with scored candidates and the aliases that matched — never a silent all-clear.

    Why it is in this group

    • The description's first verb is "validate": a word for reading.
    Description, as the server wrote it
    Validate an IBAN (length + mod-97 check digits). view='decode' resolves it to country, bank and account parts; view='format' returns electronic and paper (grouped) forms. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
