Paid ($0.01 USDC via x402). Returns the top 20 active opportunity cards by score as TEASERS — { id, slug, title, category, score, signalCount, lastSeen } only. No evidence and no productAngle (buy GET /v1/opportunity for the full card). While the index is still warming and no active cards exist yet, you get a no-charge 503 corpus_warming (never an empty charged list) — poll the free GET /v1/categories to see when cards go live. Compute-first / settle-after — you are not charged on any error. Re…

MiroShark simulation: a crowd simulation of how people react to a prompt, URL or article, with optional deep research or a prediction market. Use when an agent needs to predict how people or a market…

Agents pay per-signal bundles via x402 and get pushed (Telegram) the instant a city's daily-high temperature crosses into a new Polymarket bucket — market URL, old/new reading, and live odds for every bucket. 37 cities. Free endpoints (cities, sample, pricing, terms) need no auth; deeper signal reads are paid per bundle via x402 (USDC on Base).

Latest direction+magnitude scorings for Polymarket events. Each row scores one (headline, market) pair with a direction (up/down/none), confidence (0-1), signed magnitude in points, composite tier (SKIP/WATCH/TRADE), and current market price.
