Obol

Obol is Stripe for x402 on XRPL. It lets developers monetize any API endpoint with real cryptocurrency payments; in a single line of code.

A merchant signs up, gets an API key and endpoint UUID from the dashboard, and wraps their route handler with obol.protect(). That's it. When a buyer (typically an AI agent) hits the endpoint without paying, they get back an HTTP 402 with machine-readable payment instructions. The buyer signs an XRPL transaction, retries the request, and gets the resource; all in one round-trip. Settlement happens on-ledger, automatically, after the business logic succeeds.

The primary buyer persona is AI agents and programmatic services, that is software that can read a 402 response, sign a transaction, and retry without human intervention. Obol turns any API into a pay-per-call service for the agentic economy.

What used to take 150+ lines of blockchain plumbing now takes 5 (which is a 97% percent code reduction). A complete merchant server fits in 40 lines including imports. And it's safe by default; developers never have to create wallets, manage private keys, or juggle environment variables if they don't want to. The dashboard generates and encrypts everything, so newcomers to crypto can start earning without touching a single secret.
