Every agent-payable API.

Domain enrichment bundle (DNS A/AAAA/MX/NS)

Combined domain health verdict in one sub-second call: authoritative RDAP registration status and expiry (per-TLD registry, IANA-bootstrapped) plus live HTTPS/TLS reachability, weighted into a single 0-100 score with per-component confidence.

Domain from an email. Call when routing tickets, grouping users, or validating corporate domains.

BTC, ETH and USDT dominance as a share of total crypto market cap — the regime filter to check before sizing any altcoin position.

Run a website due diligence and counterparty risk report with seven live checks in one call: DNS and RDAP registration, domain age, TLS, page metadata, technology fingerprint, hosting context, OFAC name screening, and GLEIF legal-entity lookup.
