Equation solver API: exact roots of linear and quadratic equations (real and complex) and 2-variable linear systems, from structured coefficients. Real algebra, not a guess.

Check any hostname's DNS records — A, AAAA, MX, TXT, NS, CNAME, SOA, CAA, SRV, or PTR — along with whether DNSSEC validates, returned as structured JSON with name, type, TTL, and data for each answer. Built for domain-verification flows, email setup diagnostics, and security-monitoring agents. Cached 5 minutes per query.

DNS resolver API: query any record type (A, AAAA, MX, TXT, NS, CNAME, SOA, CAA, SRV) for any hostname and get the full validated answer section — name, type, TTL, data — as JSON. For infrastructure checks, email deliverability, and domain verification agents.

Resolve a place name to its geographic coordinates, along with country, region, population, elevation, and local timezone for the closest five matches. Built as the bridge between human-readable locations and any API that only accepts latitude/longitude — geocode once, reuse everywhere.

Instant lookup for any 3-letter or 4-letter flight code, returning the matching airport's full name, city, country, coordinates, elevation, and local timezone from a database of 29,000+ airports. Built for booking engines, itinerary builders, and dispatch systems that need to resolve a code without maintaining their own reference table.

Look up any airport by its IATA or ICAO code and get back precise coordinates, elevation, and IANA timezone alongside the airport's name and location — useful for scheduling arrivals and departures across time zones or plotting airports on a map. Covers 29,000+ airports worldwide, resolved locally in milliseconds.

Resolve the nameservers, mail servers, or any other DNS record type for a hostname, with DNSSEC status included in the response. Useful for confirming a domain migration completed, diagnosing email delivery issues, or validating that infrastructure changes propagated correctly. Answers are structured JSON and cached for 5 minutes.

AI-relevant APIs from the APIs.guru directory of 2400+ OpenAPI specs, filtered via curated keyword matching. Per-entry first_seen_at against TensorFeed snapshot history so an agent can answer "what new AI APIs appeared in the last 7 days": a diff APIs.guru itself cannot provide. CC-BY-SA 4.0; source links preserved.

AI-stack CVE intelligence. Filters fresh security disclosures to vendors and products in the AI inference, agent framework, training, vector DB, model gateway, and MCP tool layers. Each paper carries a tf_ai_category tag and a severity_rank, sorted with exploited-in-wild and critical-severity first. 99.8% of underlying data is from GitHub Security Advisories (CC BY 4.0).

AI safety incident exposure analytics. Per-developer and per-deployer incident counts with recency-weighted exposure_score (1.0 last 30d, 0.5 days 31-90, 0.25 older), risk_domain and SEP-view (Security/Ethics/Performance) distributions, top affected artifacts. Derived over the AVID (avidml/avid-db, MIT) snapshot refreshed daily. The "which AI vendors have the most recent reported safety incidents" call.

Per-institution AI research publication velocity. 30-day window vs 365-day baseline with direction classification, notable movers, plus by-country and by-affiliation-type breakdowns. OpenAlex CC0. The "which AI labs are accelerating" feed.

AI-package security radar. Per-package risk_score (0-100) over the daily OSV snapshot of curated AI/ML PyPI + npm packages: critical_count_30d * 25 + high_30d * 12 + critical_90d * 6 + high_90d * 3 + min(open_count, 20) + 5 if any advisory in last 7d, saturated to 100. Risk_band classifications (calm <10 / watch 10-25 / hot 25-50 / critical 50+) plus notable_movers (top-5 by_critical_30d, by_risk_score, new_in_last_7d). The "which AI deps should I be worried about right now" call.

Model deprecation timeline with migration intelligence. Each entry enriched with urgency_band (within_7d / within_30d / within_60d / within_90d / past), days_until_sunset, days_since_sunset, and a resolved migration_chain hop sequence to the first still-active replacement. Optional within_days window centered on now; optional provider filter. The "is my model affected and what should I migrate to" call.

Cross-provider arbitrage analytics for hosted inference. Per-model: cheapest_paid, most_expensive_paid, spread_usd, savings_pct, median_paid_blended, fastest_tps, cheapest_with_tps, free_tier_offers. Plus provider_rollup (cheapest_count, top_tps_count, value_score 0-100) and top_arbitrage models sorted by savings_pct desc. Pairs with the free /api/inference-providers matrix. The "where to migrate workloads" call.

Enriched AI agents directory. One paid call returns the catalog joined with live provider status, recent news mentions, 24h agent traffic, and sample model pricing, ranked by a derived trending score. The agent-discovers-agent feed.

Top 50 multi-word keyphrases across recent arXiv AI abstracts ranked by recent-vs-baseline lift (last 30 days frequency over prior 90 days, smoothed). Each keyphrase carries 2-5 example arxiv_ids so an agent can drill into the underlying work. The trend-spotter feed for AI research vocabulary.

Live-threat CVE feed. Returns only papers with exploited_in_wild = stated_yes from the latest AI-flagged batch, ranked by severity. The subset answers "what AI-stack CVEs are actively being weaponized right now."

Last 30 days of arXiv preprints flagged as milestone candidates by an offline Qwen 3.6 27B per-paper extraction pass. Each paper carries structured reasoning naming the benchmark + quantified delta, model release, or novel architecture justification. Conservative; false positives are worse than false negatives.

Top 100 recent AI papers ranked by the share of their total citations earned in the most recent calendar year. Papers published in the last 2 years with 3+ citations. Surfaces papers that are still gaining traction now. OpenAlex CC0.

AI-package release velocity. Per-package releases_24h / releases_7d / releases_30d, latest bump classification (major/minor/patch/prerelease, pre-1.0 minor counts as major per semver), is_breaking_recent flag (major bump within 30 days). Notable movers: recent_major_bumps, most_releases_7d, fastest_cadence_30d. Filter by ecosystem (PyPI/npm), category (llm-sdk, agent-framework, etc), or package substring. The "what AI deps just changed and is it breaking" call.

Top 100 AI researchers ranked by AI publication volume in the trailing 365 days, enriched with h-index, i10-index, total citation count, primary affiliation (institution + country), ORCID, and derived AI-share-of-total. OpenAlex CC0. Daily refresh.

Forward and backward calendar over the AI policy registry. Each entry classified relative to now (past / active / upcoming), days-until-effective, with next-3-milestones for upcoming items. Filter by jurisdiction (EU, US, UK, etc) and time window. The "what AI rules are about to bite" feed.

Global news attention and tone for any company, ticker, or topic, from the GDELT Project's worldwide news monitoring. Pass `?q=Nvidia` (required), `?timespan=1d|3d|1w|2w|1m|3m` (default 1w). Returns average and latest tone with a positive/neutral/negative label and trend, an article-volume timeline, and recent headlines. A media-sentiment read distinct from the Reddit/4chan feeds.
