Detect AI-generated writing with a calibrated probability score. Returns a 0-1 likelihood, a verdict, suspicious phrases, and per-axis style signals (em-dash overuse, hedge phrases, formulaic transitions). Works as an AI content detector, GPT detector, or ChatGPT-text checker.

Converts text to speech with 30+ voices and 5 audio formats. Morpheus primary for Kokoro, Venice fallback and alternate TTS models (xAI / ElevenLabs / Orpheus / MiniMax / Gemini), with fal.ai storage for hosted audio URLs. Use it as a TTS API or voice generator.

Transcribes any video URL to text with Whisper v3 large. Auto-detects 90+ languages and offers a translate-to-English mode. 60-min / 500MB max. Same backend as video-to-text under a clearer slug. Use it for video transcription, video to audio transcription, or video-to-text. For speaker labels, use the speaker-diarize endpoint.

Looks up a CVE and returns the full NIST NVD vulnerability record. Short alias of cve-lookup: CVSS v3.1 + v2 vectors, severity, CWE class, affected CPE list, references, public-exploit indicator with reference URLs, and a bounded exploitability summary. Federal public data. Use it as a vulnerability lookup, NVD record fetch, CVSS scorer, vuln advisory fetch, exploit-known check, or patch-priority triage for Log4Shell-style records.

Server-side rendering; body content rendered as text, raw HTML, or clean markdown, with optional link extraction. Cheerio-based with no headless browser, so it is fast and cheap, ideal for static pages and SSR sites. For JS-heavy SPAs that need a real browser, see website-screenshot. Use it as a web scraping API or webpage metadata extractor.

Embeds 1 to 100 strings into semantic vectors via Venice. Tier shorthand: 'default' → gemini-embedding-2-preview (newest, recommended), 'fast' → text-embedding-bge-m3, 'openai-compat' → text-embedding-3-small. You can also pass a full Venice embedding model name. Returns a list of vectors aligned with input order. Use it for text embedding, vector embedding, Venice embeddings, Gemini embeddings, or BGE-M3.

Looks up ASN and geolocation for any IPv4 or IPv6 address: ASN number, ASN org, ISP, country, region, city, postal, latitude/longitude, and timezone. Primary backend: ipapi.co (1k req/day free); fallback: ip-api.com (45 req/min free). Both are free public APIs with no auth. Use it as an IP-to-ASN, IP geolocation, IP-to-ISP lookup, WHOIS for IP, or cloud-provider attribution tool.

DST is handled correctly (uses V8's built-in tzdata via Intl.DateTimeFormat). Returns both formatted strings, both UTC offsets, and the difference in hours. Use it for DST-aware time arithmetic, wall-clock to UTC conversion, or converting across cities.
