This is a symmetric integrity tag, not a vendor PKI signature or code-signing service. | - | $0.003 | listed | |
| Otto AI 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. | - | $0.003 | listed | |

Refreshed every minute. $0.001 per call. | - | $0.001 | listed | |
| Otto AI 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.

Base gas oracle, gas price, priority fee, EIP-1559, maxFeePerGas. $0.001 per call. | - | $0.001 | listed | |
| Otto AI 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.

| Otto AI 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.

| Otto AI 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. | - | $0.003 | listed | |
| Otto AI 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. | - | $0.003 | listed | |
| Otto AI Full SEC financial statements for any US-listed company by ticker: income statement, balance sheet and cash flow, five periods deep, annual and quarterly.

| Otto AI 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. Monetary estimates retain Finnhub payload units because the captured feed does not identify a currency. Event-window price drift is explicitly unavailable rather than inferred. | - | $0.003 | listed | |
| Otto AI Latest insider trades feed across ALL US-listed companies — the 20 most recent SEC Form 4 filings by acceptance time, not one ticker at a time: issuer ticker and name, filer and role, transaction code (P purchase / S sale / A award / M exercise / F tax), shares, price, value and shares held after, with EDGAR links.

| Otto AI Turn any URL into clean structured JSON for AI agents and RAG. An LLM reads the fully rendered page (JavaScript executed, SPAs included) and returns its title, a 1-2 sentence summary, key entities (people, orgs, products), and any prices, dates or notable numbers — even on pages with no schema.org or JSON-LD markup, no CSS selectors or schema to write. Just pass a URL. Keyless, pay-per-call. | - | $0.005 | listed | |
| Otto AI Form 144 filings by ticker — SEC notices of PROPOSED insider sales, filed BEFORE the Form 4 that reports the executed trade: who intends to sell, units, the filer's own market-value estimate, broker, approximate sale date and Rule 10b5-1 plan dates.

| Otto AI Schedule 13D and 13G activist stake filings by ticker: every beneficial-ownership filing made about a US-listed issuer in the last 365 days, each validated against its own cover page so a company's outbound filings about OTHER companies are excluded.
