## what's for sale

## how to buy
1. `POST https://api.onkernel.com/mpp/browsers`. the response is a 402 with a `WWW-Authenticate: Payment` challenge, which can be paid for 30 minutes.
2. pay the challenge and retry the same request with `Authorization: Payment <credential>`. with link: `link-cli mpp pay https://api.onkernel.com/mpp/browsers --method POST`.
3. the 200 response has `session_id`, `cdp_ws_url`, `browser_live_view_url` and `expires_at`. connect over cdp with playwright or puppeteer.
resending the same paid credential returns the same browser until it expires, without charging again. to get a stripe receipt, send `{"email": "you@example.com"}` as the json body.
