Midas FX Quotes is an execution-quality FX feed for agents. For any currency stablecoin on Celo (cNGN, Mento's NGNm, KESm, GHSm and PHPm, wBRL, wARS and more) it returns, per venue (Mento, Uniswap v3 and v4, Curve, Textile's RFQ desk), the rate a trade of a given size would actually execute at, the slippage, and the spread against the official rate, plus a recorded history every 5 minutes. Agents call it over HTTP and pay $0.01 a call with x402: no account and no API key. It runs on the same quoting engine as our live trading desk on Celo, and also covers Base, BSC and Polygon.
Make local-currency stablecoins usable by agents and fintechs by showing, in one call, what an FX trade will really cost and where it fills best, starting with the naira and the other currencies on Celo.
Celo and Base carry dozens of local-currency stablecoins (cNGN, Mento’s NGNm and KESm, wBRL, wARS, EURC), but nobody publishes what a trade in them actually costs. Oracle rates are not executable rates: on 6 Nov 2026, $1,000 bought 1,377,680 cNGN on Textile but only 1,330,680 NGNm on Mento, against an official rate of 1,345.90. An agent or fintech moving money through these coins cannot see which venue fills its size best, how much slippage it will take, or which pools are traps that show bots fake prices.
We built an API that quotes every venue directly from its contracts and Textile’s RFQ desk, at the size the caller asks for. One call (GET /fx/NGN?size=50000) returns each venue’s effective rate for buying and selling, slippage, spread against the official rate and the best venue per side, plus a history recorded every 5 minutes. Every quote is made with a real gas price, so trap pools show their real price. Agents find it in x402 directories and pay $0.01 per call with x402, with no account or API key.
