POST /doc/ocr

live

OCR for AI agents, $0.20 per image: scans, photos and screenshots (PNG, JPEG, WebP, GIF, max 5 MB) to exact text with line breaks and reading order preserved. One call: send a url or base64 — no upload step, no polling. No text found means a 400 and you pay nothing. USDC on Base, no account, no API key.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
