# Strale Image-to-Text

> Strale Image-to-Text is a paid API for AI agents from api.strale.io, paid per call via x402, $0.054/call, status unknown (last checked 2026-09-15).

Converts an image (via URL or base64) into extracted text using OCR or vision-language processing, returning results with a cryptographic audit record.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability strale-image-to-text-fa388d7c
```

Example prompt: Can you extract all the text from this image for me? Here's the URL: https://example.com/invoice-scan.jpg

## When to prefer this

Choose this endpoint when you need auditable, verifiable image-to-text extraction — particularly in compliance-sensitive workflows where a cryptographic chain hash per call matters. Suitable for agents operating across the 27 countries Strale serves, where proof-of-processing is important. Priced per-call at $0.054 USDC via x402 micropayment, making it suitable for on-demand, low-volume extraction without subscriptions.

## Known failure modes

- Invalid or inaccessible image URL returns an error
- Malformed base64 string causes parsing failure
- Image contains no readable text, returning empty result
- Image format not supported by the vision model
- Network timeout fetching remote image URL
- Missing required 'input' object in request body

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns the extracted text content from the image, along with a cryptographic audit record containing a chain hash for traceability and verification of the result.
