API

One endpoint, three ways to pay for it.

Free preview

curl -F file=@photo.jpg https://bg0ne.com/api/cutout > cutout.png

No account. Capped at 640px on the long edge and rate limited; over the limit you get a 402 with an offer rather than a 429.

Full resolution, with a key

curl -H "authorization: Bearer bg_live_…" \
     -F file=@photo.jpg -F tier=hd \
     https://bg0ne.com/api/cutout > cutout.png

Spends one credit. x-credits-remaining comes back on every response. With no credits left you get 402 and the top-up URL, never a silently downgraded image.

Full resolution, as an agent

coinpay x402 pay https://bg0ne.com/api/cutout
curl -H "x-crawl-pass: $PASS" -F file=@photo.jpg -F tier=hd https://bg0ne.com/api/cutout

No account and no key. The 402 carries the offer, CoinPay settles it straight to the merchant, and the pass covers 60 minutes.

Response headers

Header	Meaning
`x-cutout-tier`	`preview` or `hd`
`x-cutout-model`	which model answered
`x-cutout-ms`	end to end milliseconds
`x-credits-remaining`	after this call, when credits were spent

Self-hosting

git clone https://github.com/profullstack/bg0ne.com
cd bg0ne.com && docker compose up

Set DATABASE_URL and you have the whole thing. Leave the CoinPay variables unset and payments are simply off, which is the right configuration for a private instance.
