One key.
All APIs.

Deposit once, get one key, call any merchant on the market. Every new merchant you touch is automatically capped at $1 until you raise it — the key is just a Web2 shadow of your on-chain budget. Lose the key, lose at most your caps. Rotate it in one click.

  • Works on every listed API — AI today, any category next
  • Per-merchant lifetime cap, default $1
  • Machine-readable: agents discover, compare & pay via x402
  • No CAPTCHAs, ever. Bots are customers here

Send your agent to the API market.

ApiHood treats software agents as first-class customers: they can discover endpoints, set a hard budget, and pay for calls without a human babysitting every request.

No CAPTCHAsBots are customers here. Access is gated by budget, not by pretending to be human.
Readable pricingEach listing exposes a small price sheet so agents can compare cost before they call.
Budget sealed on-chainA tap caps lifetime loss per merchant; settlement cannot exceed the cap you set.

How it works

Three moves, then your key can call the market.

1
Deposit oncePut testnet USDG behind your ApiHood budget.
2
Get your keyUse one bearer key across listed APIs.
3
Call anythingEvery merchant starts capped; you raise limits only when you trust the spend.

Commerce without trust

Two inequalities replace the escrow agent, the judge and the guarantor. That's the whole protocol.

Loss ≤ B

Buyers never risk more than $1

Your budget is an on-chain allowance you set and only you can raise. The contract makes overcharging mathematically impossible — refunds never restore spent headroom.

dW ≤ dF

Sellers withdraw no faster than they earn

Revenue matures 1:1 against fresh demand with a 7-day age floor. After week one, every day is payday — as long as strangers keep paying.

t ≤ 28d

Dying merchants auto-refund

If inflow dies, unmatured funds flow back to the payers who sent them — automatically, within days, no claims, no judges. Every in-flight dollar resolves within 28 days.

Uniswap: x·y = k — liquidity without market makers.
ApiHood: Loss ≤ B, dW ≤ dF — commerce without trust.
RWA = Real World APIs

Built for verification, not vibes.

Public stats come from readonly Gateway endpoints; settlement, reserves, and the core contract are testnet-visible. Mainnet materials and social channels stay staged until the protocol exits testnet.

Withdraw anytimeUnspent buyer balances are withdrawable from the settlement contract.
Non-custodialBudgets live in contract logic; ApiHood cannot spend beyond your tap caps.
