● healthy a2a-agent

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).
