How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

Output

Returns a JSON object containing the recognized UTF-8 text, confidence score (0–100), word and character counts, model name ('tesseract-5'), document_id, SHA-256 hashes of input and output for verifiability, a truncated flag, total pages, and an attribution note confirming no image is stored or sent to third parties.

Example use cases

Receipt text extraction for expense tracking

“I've got a photo of a receipt encoded in base64 — can you pull out all the printed text so I can log the line items and total for my expense report? Use segmentation mode 6.”

Scanned form digitization

“Here's a base64 PNG of a scanned paper form. Extract all the printed text from it so I can parse the fields programmatically — use Tesseract psm 3 for a full-page layout.”

Screenshot text capture for data pipeline

“I have a base64-encoded WebP screenshot from our internal dashboard. Can you OCR the printed text out of it and give me the raw string along with the confidence score?”

When to prefer

Choose this endpoint when you need fast, verifiable, privacy-preserving OCR on a single machine-printed image and want no image data leaving to a third-party cloud service. It is ideal for agentic pipelines that require cryptographic proof of input/output (SHA-256 hashes), pay-per-call billing in USDC without a subscription, and a deterministic Tesseract result with a confidence score. Prefer alternatives (e.g. GPT-4o vision, Google Document AI) when handwritten text, complex layouts, or multi-language support beyond English are required.

Side effects

Image exceeds 6 MiB decoded size — request rejected
Neither 'image' nor 'image_base64' field provided — validation error
Invalid base64 encoding — decoding failure
Unsupported image format (not PNG, JPEG, or WebP) — processing error
psm value not in allowed enum [3, 6, 11] — validation error
max_chars set to 0 or above 200000 — clamped or rejected
Payment not included or insufficient USDC — 402 Payment Required
