Custara
Custara is an accounts-payable agent that takes supplier invoices the way a business already receives them — upload, API, CSV, email or vendor portal — reads each one, and scores it. A duplicate, a vendor never paid before, a changed bank detail, or a bill it cannot read clearly is held, and the company's own rule decides whether one approver or two are required. Once approved, Custara pays the vendor in USDC through Circle, and nothing moves until every check passes, with each step written into a hash-chained audit log. Built as a Next.js and Prisma app on Circle's developer-controlled wallets and w3s web SDK with a CLI and Playwright end-to-end tests, it keeps the agent inside a policy gate rather than letting it release funds on its own.
