Exa's neural web search, resold per call — no Exa account, no subscription, one
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.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
