information-retrieval

Validate an email address and return structured signals: RFC syntax validity (isSyntaxValid + reason if not), the normalized address with split local/domain, and boolean flags for isDisposable (throwaway/temp-mail domain), isRoleAccount (info@, support@, admin@, …), and isFreeProvider (gmail/outlook/yahoo/icloud/…). With checkMx (default true) it also reports hasMxRecords — whether the domain publishes MX records, looked up live via DNS-over-HTTPS — plus the MX hosts. IMPORTANT: this is NOT a deliverability or mailbox-existence guarantee (catch-all domains, greylisting, and privacy relays make that impossible to assert from a single lookup); hasMxRecords reflects DNS MX presence only. Useful for signup-flow hygiene, lead scrubbing, and flagging disposable/role addresses before sending.

Browse Kalshi events (an event groups related markets, e.g. an election or a game). Filter by status / series_ticker; page with limit + cursor. Returns event ticker, series, title, category, and market count. Read-only (no Kalshi key needed).

List a user or organization's repositories (each with stars, forks, language, topics, license, timestamps). Sort by updated/created/pushed/full_name; filter type owner/member; paginate. Read-only; no caller key needed.

Check an IP address against 15 major DNS blacklists (Spamhaus, Barracuda, SORBS, etc.) simultaneously — returns which lists it appears on, a reputation score, and a threat classification so agents can make block/allow decisions instantly.

Generate brandable startup/product names from a keyword using prefixes, suffixes, blends, and phonetic patterns, then check .com (or any TLD) availability for each via DNS — returns available names ranked by a brandability heuristic so agents can find a claimable brand without manual brainstorming plus one-by-one availability checks.

Parse and validate any phone number in any format, identify its country, line type (mobile/landline/VOIP/toll-free/premium), carrier region, and return all standard format variants — so agents can validate contacts, normalize phone data, and classify line types without a paid telecom API.

Translate many independent strings in one request — each with a caller ID preserved in the response — with per-item status, glossary and tone support, and partial success so one bad item never fails the batch, so agents can localize whole string tables in a single call.

Query a domain's DNS record across 10 geographically distributed public resolvers simultaneously — returns what each resolver sees, whether results are consistent, propagation percentage, and a readiness score so agents can confirm DNS changes have fully propagated globally.

One call vets a URL end to end — traces its full redirect chain, checks it against malware/phishing databases, audits its security headers, and inspects its SSL certificate — concurrent with graceful partial-failure handling, so agents get a complete safety verdict before following a link.

Resolves all DNS record types for a domain, parses SPF/DKIM/DMARC from TXT records, and compares A records across Google/Cloudflare/Quad9 resolvers for propagation consistency.

Fetch a repository's README, decoded to UTF-8 text (name, path, size, content, URL). Optionally pin to a branch/tag/sha via ref. Useful for summarizing or indexing a project. Read-only; no caller key needed.

Fetch a page from a tollbooth-registered domain. Costs the publisher's fee_credits from your credit balance (top up at /credits/buy) plus this route's price; 80% of the fee accrues to the publisher. Returns extracted page content. 404 if the domain isn't registered; 409 (not 402) if your credit balance is short.

Look up an ISO 639 language. Pass code in any form — 639-1 (en), 639-2/B (ger) or 639-2/T (deu) — or name (English, partial match). Returns the English name and all sibling codes (alpha-2, alpha3-B, alpha3-T), so you can normalize a messy language tag to canonical ISO identifiers and resolve the bibliographic-vs-terminological alpha-3 split (e.g. German = de / deu / ger). Bundled authoritative ISO 639 data.

Look up country metadata via REST Countries. Pass alpha2 (2-letter ISO 3166-1), alpha3 (3-letter), or name (with optional fullText=true for exact match). Returns common + official name, ISO codes, region + subregion, independence + UN-member flags, capital(s), population, area km², landlocked flag, neighboring borders (alpha-3), timezones, currencies (code → name + symbol), languages, calling code, flag emoji + SVG/PNG URLs, lat/lng coordinates, Google Maps + OSM URLs, driving side, top-level domains.

Look up an IETF RFC by number. Pass number as RFC2616, 2616, or the integer 2616. Returns the RFC title, authors, publication date, status (e.g. INTERNET STANDARD, PROPOSED STANDARD, DRAFT STANDARD, INFORMATIONAL, EXPERIMENTAL, HISTORIC, BEST CURRENT PRACTICE), stream (IETF/IAB/IRTF/Independent/Legacy), DOI, canonical rfc-editor.org URL, and the full standards relationship chain: which RFCs this one obsoletes / is obsoleted by, and which it updates / is updated by. Authoritative data from the IETF/RFC Editor index. Use this to resolve whether a spec is current or superseded before relying on it.

Fetch a Wikidata entity (Q42, P31, etc.) — structured knowledge-graph record with labels + descriptions + aliases in selectable languages, claims (property → value statements grouped by property ID), sitelinks (Wikipedia article title per language). 110M+ entities. CC0 public domain. Pass languages= as comma-separated codes (default "en") to control which language strings are included; pass maxClaimsPerProperty to cap how many statements come back per property (default 10).
