invinoveritas /x402/seller-intel — recomputable x402 BUYER intelligence + a verdict on why you're buried: pass a {wallet} for its on-chain behavior (catalog-walker vs real-customer verdict, spend, the sellers winning its money), or your {domain} for a DISCOVERABILITY audit (catalog offset + the daily-crawl mechanics). Seller intelligence no other listing offers. Pass a buyer {wallet} and get its on-chain behavior (catalog-walker vs real-customer verdict, total spend, the sellers winning its money, daily crawl cadence); or pass your {resource}/{domain} and get a DISCOVERABILITY audit — your exact CDP-catalog offset + freshness, how the recency-ranked depth-first daily crawl (~04:00 UTC, NOT keyword-filtered) actually finds listings, why you're buried, and the honest levers. Recomputable from public Base RPC + the CDP catalog. Free framework at GET /x402/seller-intel/preview. POST {wallet} or {resource}; pay-per-call USDC on Base; no subscription. • Or get it all in one governed call — reason + this + memory, passed through governance and remembered to your wallet-keyed home — for less than the sum: POST /residence/act (a home for your agent).

Searches for user accounts and returns matching results.

Retrieves user account information or user listing data.

Returns a list of email inboxes or mailbox accounts.

Fact-check a claim by searching for evidence online

Verify up to 100 emails in one call; returns a per-email record matching /verify.

Validate a UK postcode and report its normalised form, format validity, and whether it is currently active.

Check whether a domain has valid MX records and is not on the disposable list; also reports free-provider.

Return raw MX records (preference + exchange host) for a domain, sorted by preference.

Look up domain registration metadata via RDAP — returns registrar, creation/expiry dates, nameservers, status flags, and an actionability score so agents can assess domain trustworthiness or availability risk.

Fetch metadata for any npm package — download counts, latest version, all versions list, dependencies, maintainers, repository URL, license, and a health score based on maintenance signals — so agents can evaluate dependencies, audit package ecosystems, and assess supply chain risk.

Query the Internet Archive Wayback Machine to check if a URL has ever been archived, get the closest snapshot to a given date, retrieve the most recent capture, and return archival history stats — so agents can access historical web content, verify past content claims, and recover deleted pages.

Calculates IPv4/IPv6 subnet details from CIDR notation including network/broadcast addresses, netmask, usable host range, supernet, and possible subnets; for multiple CIDRs, detects overlaps and classifies relationships.

OFAC SDN sanctions screen for a name / entity / wallet (?name=)

Trace an HTTP redirect chain to its final destination without downloading page bodies. Returns every hop (URL + status), the final URL, and safety warnings — link-safety grounding for agents before they visit or cite a URL. Clean JSON.

Cheap, fast "is this a dateable event?" filter for social and web text — one tiny Haiku call returns is_event, confidence, and a one-line reason, so agents can screen every post for free-ish and only pay for full extraction on the ones that pass. Front-end filter to /event-extract; intentionally minimal output for cost/latency discipline.

Research keywords with Google autocomplete suggestions, related queries, and intent classification

Discover subdomains for a domain via Certificate Transparency logs (crt.sh); returns a de-duplicated, sorted list.
