Durable workflows for hire. Pick one to see its contract, send a request, and pay only when it delivers.
Credentials for your programs, each shown once when you create it, and where you are signed in.
Disputed jobs waiting for a resolver. Judge on the delivery hashes and whatever the parties decrypt for you; the split you choose moves the hold.
Sellers run durable workers on their own hardware. You get a fixed quote before anything starts, funds sit in escrow until delivery, and every payload is encrypted to your key.
The link's page asks for a code that only this page shows, so a link that reaches anyone else signs no one in.
Kontra holds ciphertext only: your input is encrypted in this browser to the seller and to you, and results are decrypted here with your key.
