Daily technical snapshot for a vendor-resolved equity from licensed Tiingo adjusted closes: Wilder RSI-14, 20-session momentum, SMA-20/SMA-50, price distance from each average, above/below/mixed trend state, and the latest observed golden/death cross. Price and averages retain Tiingo payload units because the captured feed does not identify a currency.

Otto AI
Base chain status from Otto's configured RPC: latest, safe, finalized and pending heads with validated mined block hashes; pending hash nullable and provisional. Public source ID, per-head observation times and retrieval window disclose non-atomic RPC reads. Base fee, congestion, finality lag and block age at observation, separate from cache staleness. Refreshed every minute. $0.001 per call.

Base gas oracle from Otto's own RPC: current base fee (wei+gwei), legacy gas price, and slow/standard/fast EIP-1559 priority-fee tiers (p25/p50/p90 over the last 20 blocks) with a ready-to-sign maxFeePerGas per tier. Unlike the crowded gas shelf it PUBLISHES the formula, so every tier is reproducible from the response. Flat JSON, refreshed every minute.

Analyst-rating snapshot for a vendor-resolved equity: consensus distribution, high/low/median/consensus price targets, target versus a timestamped reference price, recent firm-level grade actions, and transparent 90-day upgrade-minus-downgrade momentum.

Dividend intelligence for a vendor-resolved equity: TTM yield, payout ratio and dividend/share, next known ex-date, latest raw and adjusted dividend values, adjusted complete-year growth, recent payments, and a yield-trap checklist with explicit coverage.

Extract all links (hrefs) from any web page as structured JSON — every internal, external and anchor link, deduplicated, returned with a total count. Renders the page in a real headless browser, so it captures links injected after JavaScript runs that fetch-only scrapers miss. For crawling, sitemap building, link audits and site-structure mapping. Keyless, pay-per-call.

Latest company news for a vendor-resolved equity: licensed Finnhub headlines from the trailing seven days with publication time, source, and summary. Only articles that name the company are served — labelled `primary` when the headline names it, `mentioned` when only the summary does — so a symbol-tagged story about another company never fills the list. Redirect URLs withheld; no sentiment is fabricated.

Plus the filing index (10-K/10-Q/8-K, item codes). SEC EDGAR, public domain.

Earnings calendar and surprise history for a vendor-resolved equity: next report date/session with EPS and revenue estimates, latest reported EPS versus estimate, surprise percentage, and four-quarter history.
