Bido-Arc

Bido is a real-time intent auction protocol for the agent economy. We turn paid APIs into competitive auctions where sponsors bid in USDC to pay for AI agent calls-capturing high-intent decisions instead of probabilistic clicks. THE PROBLEM AI agents burn money on every API call. Search, flights, products — every query has a cost, passed to users or eaten as overhead Meanwhile, brands spend billions on display ads chasing low-intent eyeballs, when they could be paying directly for high-intent moments. SOLUTION Bido inserts a real-time auction layer between agents and paid APIs. When an agent triggers an API call, the API responds with HTTP 402 Payment Required. Bido opens an on-chain auction. Sponsors compete in sub-second USDC bids. The highest bidder pays the API. The agent gets data for free. The sponsor captures a deterministic, high-intent decision. WHY ARC+CIRCLE Each auction settles 4–5 on-chain transactions. On Ethereum, that's $5–20 in gas — destroying any business model. On Arc, it's a tenth of a cent. This protocol cannot exist elsewhere. We built Bido Circle-native, using five Circle products: Arc Testnet as L1 (sub-second finality) USDC for all settlement USDC as gas (predictable fees) Circle Wallets API for sponsor onboarding (email + KYC, no MetaMask) Nanopayments materialized in code DUAL ONBOARDING-KEY INNOVATION Bido supports two sponsor onboarding modes in the same protocol. Web3-native sponsors (Delta, United) use MetaMask via ethers.js. Traditional brands (JetBlue) onboard via Circle Wallets API — no private keys, server-side signing through Circle SDK. Both compete in the same auctions. Both settle on Arc in USDC. The market doesn't care how they signed in. PROOF 100+ on-chain transactions executed. Smart contract deployed on Arc Testnet. Three sponsor wallets actively bidding. Live dashboard showing auction history, leaderboard, and economics. Verifiable on Arc Block Explorer. Bido. Monetize decisions, not clicks. Built on Circle.
