One OpenAI-compatible key. Every call goes to the cheapest healthy seller, and you pay in USDG from your own wallet.
Illustration only. Sellers set their own discount, and no real seller is connected yet.
No sales call and no card. Sign in with a wallet on Robinhood Chain, fund a balance, and send a request.
Sign in with an Ethereum-style wallet on Robinhood Chain. No email, no password, and signing in cannot move funds.
Send USDG from your own wallet. One USDG adds one dollar of balance, credited once the receipt is on-chain.
Create a capped key and change the base URL. Each call goes to the cheapest healthy seller, with fallback.
Point your SDK at one base URL. heura compares seller offers, skips the unhealthy ones, and sends each request to the seller with the deepest discount. You are billed list price minus that discount, and if a seller fails the call falls back to the next one.
Five steps, and every one can be checked on the Robinhood Chain explorer. Nobody approves a payment by hand.
Choose an amount. You get the payee, the USDG token and a one-time reference.
One transfer plus the reference, signed by you. We never hold your keys.
The server reads the transaction on-chain: payee, token, amount and reference.
One USDG adds one dollar, once. The same payment can never be used again.
Each call is billed at list price minus the winning seller's discount.
Balance cannot be sent or cashed out, only spent on calls. Refunds for a failed call after payment are recorded and handled by the operator.
heura speaks the OpenAI API your tools already use. Base URL: https://api.useheura.com/v1. Keys are created in the app.

client = OpenAI(

heura is not launched, so there are no volumes or customer payments to show. Every payment it will take is an ordinary USDG transfer on Robinhood Chain, readable by anyone on the explorer.
Build with one key, let an agent pay per request, or sell your own capacity. All three meet in one market.
Use inference at the best available price
Pay one request at a time, no account
Sell spare provider or GPU capacity
Checks ran locally and in automated tests, not with customer funds. That is evidence, not a guarantee, and the gaps are listed beside it.
Order matters: the money path is checked first, then the product around it. Nothing below is claimed as live.
