Upstream
Part of the Toolweather suite. The same tools are also available on the Toolweather MCP at https://toolweather.toolweather.workers.dev/mcp (proxied here). This Worker remains the source of truth for REST, digests and x402 payments.
Live status and breaking-change feed for the AI and developer APIs agents depend on: outages, model deprecations and retirements, pricing-page changes. ~40 providers.

Free tier
500 calls/day with a free key (POST /v1/keys), 50/day anonymous, 1 free change-alert webhook. Above that, pay per call with x402 (Base mainnet, real USDC): /status/:provider $0.003, /model/:id $0.003, /changes $0.01, extra watch $0.05/30 days.
Stack
Cloudflare Worker (free plan) + D1, Hono, @x402/hono with the PayAI facilitator (Base mainnet). Pay-to address, network and facilitator are env vars in wrangler.toml, so switching to mainnet is a config change.
Cron every minute: a quarter of the providers per run (each provider ~every 4 min), one tracked docs page every 5 min.
