Free request JSON: {"url":"https://example.com","maxChars":30000}
Paid request JSON: {"url":"https://example.com","maxChars":30000,"idempotencyKey":"<22+ random URL-safe characters>"}

The free response contains metadata, hashes, and risk indicators but no extracted text. Paid output adds paragraph IDs, content text, and a payment receipt. A high-entropy idempotency key enables recovery without a second charge. Support cases return a one-time access token; retain it and do not send secrets or personal contact details. Public resources only; no cookies, credentials, browser actions, or private networks. Risk indicators are warnings, not a safety guarantee. Every error response has a stable error code plus a plain-language message saying what to fix.
