Every relay is measured twice over. Over WebSocket a genuine REQ query is sent and the connection time, the time to end of stored events and the number of events returned are recorded — a relay that accepts the connection and then stays silent is the failure mode a reachability ping cannot see.

Fetches the feed over https with redirect and size limits, recognises RSS 2.0, RDF and Atom, and converts each entry into a NIP-01 event. Kind 1 produces a short note built from title, optional shortened summary and the link; kind 30023 produces a long-form article carrying the full entry text plus the title, published_at and d tags that NIP-23 expects.

Accepts three forms of recipient. A bech32 lnurl is decoded to its callback URL, a Lightning address is resolved through the well-known lnurlp path, and a Nostr public key is resolved by reading its kind 0 profile from relays and taking the lud16 or lud06 field it publishes.

Fetches https://domain/.well-known/nostr.json with the name query parameter and reads the mapping the domain publishes. The answer states the resolved public key in hex and as npub, the relay hints the document lists for that key, and the HTTP status and final URL after redirects, so a redirect to a login page is distinguishable from a genuine answer. Given an expected public key, the comparison is made and the result is reported as an explicit match or mismatch rather than left to the caller.

Fetches the recent notes of one public key across several relays and measures six independent signals: posting rate per day, the coefficient of variation of the intervals between posts, how many of those intervals sit within a few seconds of each other, the entropy of the hour-of-day distribution, the share of posts whose text repeats an earlier post verbatim, and the largest burst inside sixty seconds.

Screen physicians industry is already paying — the recipient side of the CMS Open Payments (Sunshine Act) file, ranked by total reported payment amount. Filter by specialty, state, nature_of_payment, and min_amount. Prescriber name / specialty / state / city are resolved by joining the NPI to the CMS Part D Prescribers file (Open Payments carries none of them). Public CMS provider-level data; not a consumer report.

Complete domain intelligence in one call — WHOIS, multi-resolver DNS, SSL/TLS, tech stack, security headers, subdomain discovery, redirect chain. All 7 run in parallel with individual timeouts. Partial results on component failure. Weighted overall security grade. Doing this yourself requires 7 separate tools and result aggregation. Accepts USDC payments on Base and Solana

ERC-8004 Inspector agent lookup (identity + reputation) — per call

Collects kind 9735 zap receipts addressed to one public key over up to twelve relays, merges them by event id and reports who sent how much over the requested window. Every amount comes from decoding the BOLT-11 invoice carried in the receipt, not from the amount tag of the zap request, because the two can disagree and only the invoice was payable.
