Screenshots.

Render any page in a managed headless Chrome and get a PNG back. Every render happens in a fresh, incognito-style browser context that is disposed afterwards, and every request is paid for with a proof-of-work token — no accounts, no API keys. Results are cached for an hour.

Request

GET /shot?token=<token> where the token is a proof of work over the request document described below. The response is image/png; an x-cache: hit header marks answers served from the hour-long cache. GET /shot/config returns the required level as JSON, currently as {"level": …}.

GET /shot?token=eyJ1cmwiOiJodHRwczovL2V4YW1wbGUuY29tLyIsIndpZHRoIjo4MDAsImhlaWdodCI6NjAwLCJzY2FsZSI6MC41LCJ0cyI6MTc1MjYwMDAwMH0.AAAmB0i-4vE

Document

The proof-of-work document is a JSON object with exactly these fields (no extras, any order):

url: http or https page to render. Non-public addresses are refused.
width, height: Render viewport in CSS pixels, integers from 1 to 2048 each.
scale: Optional downscale factor in (0, 1], default 1. The PNG comes back at width×scale by height×scale pixels; Chrome does the scaling.
ts: Current Unix time in seconds. Accepted within 5 minutes either way, so tokens cannot be stockpiled.

Solve to the level from /shot/config — default 24, sized so a GPU pays a few milliseconds and browser workers a few seconds — with any solver from the proof-of-work page:

doc=$(jq -nc --arg url https://example.com/ \
  '{url: $url, width: 800, height: 600, scale: 0.5, ts: now | floor}')
curl -sG https://cc.me/shot --data-urlencode "token=$(node pow.mjs solve 24 "$doc")" -o shot.png

Identical documents (ignoring ts) hit the same cache entry, so retrying within the hour is free for the server and instant for you.
