Simple exponential smoothing (SES) - level-only forecast for series without trend or seasonality. Higher alpha (closer to 1) tracks recent values aggressively; lower alpha (closer to 0) smooths through noise. Default alpha=0.3 is a common conservative pick; pass an explicit alpha or use forecast-eval to pick the one that minimizes backtest error. Forecast is flat (= last fitted level) for all horizons.
Resolve a public product redirect, canonical URL and stable provider identifiers using bounded HTTP and structured data. It does not execute JavaScript or assert unavailable facts.
Resolve requested product options to a canonical public variant when the provider exposes them. Ambiguous or missing options are reported explicitly; no checkout or cart mutation occurs.
Return structured application fields/questions where publicly exposed.
Extract PDF/CSV/XLS/XLSX/ZIP/JSON/XML links from static public HTML by suffix or download filename. Resolve relative/base links and deduplicate. Limits: 500 links, 8s, 5 redirects, 2 MiB. No JavaScript or file downloads; existence, MIME, size and file safety are unverified. Empty results are valid. 0.003 Base Sepolia test USDC per success; invalid inputs/errors are not settled.
Detect bounded changes across one static page surface using one HTML fetch plus at most one robots.txt fetch. Forest hashes HTTP identity, page metadata, normalized JSON-LD, downloadable links, form schema and robots context without storing snapshots, rendering JavaScript or submitting anything. Base mainnet USDC
Extract bounded generic metadata and normalized JSON-LD entities from one static public HTML page. Forest returns only compact fields and key/type summaries, never arbitrary raw JSON-LD; JavaScript rendering and domain-specific business interpretation are excluded. Base mainnet USDC
Interpret the robots.txt crawling rules that apply to a specific public URL and user-agent before an automated fetch or crawl. Returns allow/disallow decision evidence, matched rules, crawl delay and sitemap hints from one bounded robots.txt read. This is protocol guidance, not authorization or an anti-bot bypass. Base mainnet USDC
Extract the main article/content body from one bounded public static HTML page as clean text and conservative Markdown. Forest deterministically selects article-like content, strips common navigation/footer/form/aside/consent chrome and returns bounded metadata. No JavaScript rendering, link following, authentication or model inference. Base mainnet USDC
Locate a website sitemap before crawling by reading sitemap declarations from robots.txt and, when none are declared, checking only the conventional same-origin sitemap.xml and sitemap_index.xml locations. Returns verified sitemap discovery evidence without crawling sitemap entries or site pages. Base mainnet USDC
Extract PDF/CSV/XLS/XLSX/ZIP/JSON/XML links from static public HTML by suffix or download filename. Resolve relative/base links and deduplicate. Limits: 500 links, 8s, 5 redirects, 2 MiB. No JavaScript or file downloads; existence, MIME, size and file safety are unverified. Empty results are valid. Base mainnet USDC
Detect meaningful changes in normalized static page metadata and JSON-LD with a deterministic semantic hash. Transport noise and malformed JSON-LD counts are excluded; truncated structured output reports unknown when the observed prefix is unchanged. Base mainnet USDC
Extract a bounded normalized set of public HTTP(S) anchor links from one static HTML page. Forest resolves relative and base URLs, deduplicates by final absolute URL and classifies returned links as same-origin or cross-origin. One page fetch only; no linked URL is requested or crawled. Base mainnet USDC
