## Core API

- `GET /v1/screenshot`: query-string screenshot endpoint.
- `POST /v1/render`: JSON screenshot or PDF endpoint.
- `GET /v1/usage`: authenticated plan and monthly-quota status.
- `POST /v1/upgrade-requests`: authenticated request for a higher paid plan; no payment is taken.
- `POST /api/trials`: issues one Free-plan key per email; its 100 successful renders renew each UTC calendar month and the key is returned once.
- `POST /mcp`: authenticated stateless MCP Streamable HTTP endpoint with `capture_page` and `get_usage` tools.

Authentication uses a Bearer API key. Only successful renders consume quota. JPEG quality is caller-selectable from 1–100 and defaults to 85. Local, private, link-local, and special-use destinations are blocked. Optional best-effort controls block known third-party ad/tracker/chat hosts and hide common cookie-consent or newsletter/signup/discount overlays without clicking or submitting. Arbitrary browser scripts, CAPTCHA solving, proxy rotation, and anti-bot bypass are not offered.

## Current beta evidence

Production benchmark: 197/200 preflighted HTML pages rendered successfully, 2.42-second p50, 7.68-second p95. This is not an SLA.
