Exa's own page index, read per call — no Exa account, no subscription. Pass urls= (one, or up to 5 comma-separated) and get each page as clean text with title, author and publish date. Answers from Exa's crawl rather than our fetcher, so it reads pages a plain server-side GET is blocked from. maxChars=500..40000 (default 8000). One URL is $0.002; a batch of 2-5 is $0.008, which the 402 challenge quotes. Pairs with exa-search: search, then read the winners.

Exa's neural web search, resold per call — no Exa account, no subscription, one USDC micro-payment. Pass query= and get ranked results: title, URL, publish date, author, relevance score. numResults=1..10 (default 5). type=auto|fast|instant. includeDomains= restricts the search. Add text=1 for matched highlights from each page (caps results at 5, priced $0.03; the 402 challenge quotes it). For agents that need what the web says today, not what a training cutoff remembers.

Ask a question and get a written answer with the sources it was drawn from. Exa searches its index, reads the pages and composes the answer, returning the citation list (title, URL, published date) alongside it so every claim can be checked. Model-backed: the answer text is generated, the citations are retrieved.

Neural (embedding-based) web search over Exa's curated index, which finds pages by meaning rather than keyword overlap. Use it when a keyword engine returns the wrong thing: conceptual questions, 'pages like this one', or niche technical writing. Returns up to 10 results with title, URL, published date and author. Complements the Brave-backed web search rather than replacing it.

Retrieve the readable text of up to 10 web pages by URL, with optional query-focused highlights. Exa serves from its crawl cache when the page is fresh enough and live-crawls otherwise, so this answers for pages a plain fetch would be blocked from. Returns per-URL status so a page that could not be read is named rather than silently missing.

Exact dated owner-program windows for a US place. Perfect for: 'program deadlines in the next 180 days', 'which property program dates recently passed'. Deterministically filters exact ISO dates printed in cited registry rows; it does not infer dates from narrative rules. Charge-free when no upcoming or recently passed item returns.

Get an inspectable exact solution to a 1-8 variable rational linear system. Returns rank, pivots, particular solution and null space; distinguishes unique, inconsistent and underdetermined systems. No floating-point conditioning or physical-model assessment.

Markets (tickers) listed on one exchange: base/target pair, last price, 24h volume, USD- and BTC-converted last price and volume, bid-ask spread %, trust score (green/yellow/red), anomaly and stale flags, trade URL and last trade time. Filter by `coins` (coin ids, max 10); pages of up to 100 tickers (`page`), trimmed to `limit` (default 50). Where is a coin actually trading, at what spread, and is the volume trusted. Cached in-process for 60 seconds.
