Live FX markets for the world's currencies, onchain, traded by a robot.
Bureau watches 14 Mento stablecoins on Celo (dollars, euros, shillings, reais, pesos and more), trades them automatically when onchain prices drift from real-world exchange rates, and sells its live data to anyone, human or AI, for fractions of a cent per call. Every number below is backed by a real blockchain transaction.

Questions people ask
Yes. Real stablecoins on Celo mainnet. Every trade, payment, and payout in the tables above links to a public blockchain transaction you can verify yourself.
Nobody. The agent holds its own wallet, decides its own trades on a fixed loop, pays its own gas, and runs unattended. Humans only set the guardrails: trade size, daily cost cap, kill switch.
Request any paid endpoint and you get HTTP 402 with payment details. Your wallet signs a USDC micro-payment (no gas needed) and the retry returns your data. The code snippet above does it in 10 lines.
Edge: it bought a currency for less than the real-world rate says it's worth. Rotation: it recycled a position back to base for pennies of spread, keeping capital moving.
