# Sift Web Tools

Pay-per-call web tools for agents. Every paid route is a GET with query parameters and costs a fixed USDC amount on Base through x402; you are only charged when the call succeeds (HTTP 200). Use /v1/fetch for readable page text, /v1/metadata for titles and structured data, /v1/screenshot for a PNG, /v1/pdf for PDF text, /v1/site-check and /v1/whois for domain facts, /v1/email-check before emailing, /v1/tech for a site's stack, /v1/links, /v1/tables, /v1/feeds and /v1/sitemap for crawling, and the AI tools /v1/summarize, /v1/ask (grounded Q&A with quotes) and /v1/extract (named fields as JSON) on any page. File tools take a file URL: /v1/audio/analyze and /v1/audio/normalize (EBU R 128 loudness to broadcast or streaming targets), /v1/video/inspect and /v1/video/storyboard (scrub-bar sprite sheets plus WebVTT), /v1/dmarc/parse and /v1/dmarc/inspect (DMARC aggregate reports with real alignment), /v1/geo/convert and /v1/geo/inspect (GeoJSON, shapefile, CSV, GPX, KML, any CRS). Generation: /v1/image (text to image) and /v1/tts (text to speech). Also /v1/search (live web search with sources), /v1/doc-to-markdown (Word, Excel, PowerPoint, PDF, EPUB to Markdown), /v1/ocr (text from images) and on-chain lookups /v1/crypto/balance, /v1/crypto/token, /v1/crypto/tx and /v1/crypto/ens on ethereum, base, arbitrum, optimism and polygon, plus /v1/crypto/token-risk (risk score from on-chain code), /v1/crypto/contract (proxy, owner, capabilities) and /v1/crypto/gas (live fees on 5 chains), /v1/roast (funny AI roast of a token, website or project), and free tries of ens, gas, email-check and whois under /free/v1/. Text tools: /v1/translate and /v1/classify (sentiment, topics, your own labels). Speech: /v1/transcribe (Whisper, SRT or VTT). Creator tools: /v1/yt/metadata (titles, tags, description), /v1/yt/thumbnail-check, /v1/yt/script and /v1/yt/translate-subtitles and /v1/yt/check-subtitles.
