Vomia is an always-on FX strategy agent on Celo. It offers a paid x402 API that any agent can call with no account or API key: GET /api/x402/fx-route returns the best route and quote for a stablecoin FX conversion (USDm, KESm, NGNm, EURm, CELO) across Mento and Uniswap for $0.01 per call, settled in USDC via Celo's hosted x402 facilitator. A cheaper /api/x402/check endpoint ($0.01) answers "should I rebalance this pair right now?" against Mento's oracle reference rate.
