Look up any Ethereum address — returns entity labels, name tags, and categories from 412K+ labeled addresses. AI agent API for on-chain identity resolution

Uploads an image to Twitter/X for the authenticated user and returns a media_id to attach to a tweet. Send the file as multipart/form-data field "file" (e.g. -F "file=@photo.jpeg"); pass auth_token and ct0 as query params. Returns media_id, media_id_string, media_key, size, expires_after_secs, and image metadata.

Get the latest tweets that mention the authenticated user (the notifications timeline). Returns up to 20 tweets per page, most recent first, with pagination support. Query params: auth_token (string, required) - Twitter auth_token cookie; ct0 (string, required) - Twitter ct0 cookie; type (string, optional) - notifications timeline to read: All (default), Priority, or Mentions; next_token (string, optional) - pagination cursor.

Fetch any public URL and extract structured metadata — Open Graph tags, Twitter Card tags, canonical URL, title, description, favicon, article author/date, JSON-LD structured data, and content type — so agents can preview, classify, and enrich links without building their own scraper.

IP geolocation lookup (geoip / IP location API) — geolocate any IPv4 or IPv6 address to city, region, country, latitude/longitude, timezone, and ISP/ASN as structured JSON so agents can localize content and enrich user records without a paid geolocation subscription. For proxy/VPN/anonymizer or hosting/datacenter detection, use /ip-risk/score or /ip-reputation/analyze.

Validate a domain's DNSSEC configuration over DNS-over-HTTPS: DS records at the parent zone, DNSKEY records at the domain, RRSIG signatures, NSEC/NSEC3, plus the validating resolver's AD bit — returns a full chain-of-trust assessment and readiness score so agents can verify DNS integrity before trusting resolution results.

One call returns a complete risk profile for an IP address — geolocation, ASN/network owner, blacklist status across multiple DNSBLs, and proxy/VPN/hosting classification — aggregated into a single verdict so agents can make a block/allow decision without calling four separate IP endpoints.

WHOIS domain lookup via RDAP — registrar, creation/expiry/updated dates, nameservers, and status flags from the authoritative registry, plus an actionability score so agents can assess domain trustworthiness, ownership, or availability risk.

Vet and pick a domain in one call — give candidate names, get back a ranked verdict on which to use and whether it's safe to build on: availability across TLDs, name quality, typosquat exposure, and a factual brand-collision check against similar existing names. Collapses the pick-a-brand-name funnel into one call. Search terms: vet a domain, pick a brand name, check domain before building, choose startup name.

Determine a domain's age from registration data and archival history — tries RDAP, then port-43 WHOIS, then a Wayback-based estimate (age_source: rdap | whois | wayback_estimate | null), returning creation date, age in years, first Wayback capture, archived snapshot count, and a maturity signal so agents can assess trustworthiness and detect freshly registered domains used for fraud or phishing — including .io and TLDs without public RDAP.

Call OpenAI's gpt-5.4 via a single pay-per-call x402 endpoint — no OpenAI account or API key needed, pay $0.25 per request in USDC. Standard OpenAI chat.completions request/response shape, capped input and output. Search terms: OpenAI, gpt-5.4, chat completion, LLM, no API key.

Observed Surface Comparison Facts API

Domain age and registration intel from authoritative RDAP/WHOIS records: exact creation date, age in days and years, expiration date and days-until-expiry. The fast trust and risk signal agents use to vet a counterparty, link, or sender and to flag newly-registered or soon-to-expire domains. Returns structured JSON, keyless, pay-per-call. ccTLDs without RDAP return an uncharged 503.

Neural web search for agents (Exa upstream): pass a query, get the most relevant live web pages with title, URL, published date, author, relevance score and a clean text snippet as structured JSON. The find-then-read pair for /web-extract — RAG retrieval, research, fact-finding, monitoring. Keyless, pay-per-call, cached by query. A no-match query returns an empty result set as a valid answer.
