Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Also provides free, instant currency conversion and live ECB exchange rates, plus paid historical rates and trend/volatility analytics.

Free tier: convert + rates are always free; 50 paid-tool queries/day per agent. Then x402: the tool returns an HTTP-402 with a Solana USDC payment memo — pay it, re-call with the same args plus payment_tx=. An Authorization: Bearer fnet_… key bypasses the paywall.
