# Strale OG Image Check

> Strale OG Image Check 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).

Checks whether a URL returns a valid Open Graph image (og:image meta tag) and whether that image is accessible

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-og-image-check-a11dd59a
```

Example prompt: Can you check if https://example.com/blog/my-post has a valid og:image tag and whether the image is actually accessible?

## When to prefer this

Choose this endpoint when you need to verify Open Graph image presence and accessibility for a specific URL with a tamper-evident audit trail. Prefer it over general HTML scraping tools when you specifically need og:image validation with compliance-grade logging, or when operating in a context where cryptographic audit records are required.

## Known failure modes

- Target URL is unreachable or returns non-200 status — og:image cannot be extracted
- URL has no og:image meta tag — returns absence result
- og:image URL present but image itself returns 404 or is inaccessible
- Malformed URL input — request rejected with validation error
- Timeout on slow-responding target URLs

## 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 whether the target URL exposes a valid og:image meta tag, the resolved og:image URL if present, whether that image URL is reachable (HTTP status), and a cryptographically hashed audit record for the call.
