How this service works

Pay-per-call image intelligence for agents: generate an image from a text prompt (FLUX.1 schnell, PNG bytes or base64 JSON), or describe any image you point at by URL or base64 (LLaVA 1.5 7B, answers your own question about the picture). You are only charged when a valid result is returned.

Output

A JSON object containing the model identifier ('model'), the question asked ('question'), a natural-language answer or description ('description'), the size of the image processed in bytes ('image_bytes'), and an ISO 8601 timestamp ('generated_at'). Charged only when a valid description is returned.

Example use cases

Automated product image audit

“I have a product listing image at https://store.example.com/items/shoe-red.jpg — can you check whether it actually shows a red shoe, describe what's in the image, and flag anything unexpected?”

Accessibility alt-text generation

“Generate a descriptive alt-text caption for the image at https://blog.example.com/hero-banner.png so I can add it to our website for screen-reader users.”

Screenshot content extraction

“Here's a base64-encoded screenshot of an error dialog — can you read the exact error message text shown on screen and tell me what it says?”

When to prefer

Choose this endpoint when you need pay-per-call, zero-subscription image understanding with a custom question over any image URL or base64 blob. It is ideal for agents that need occasional vision queries without managing API keys or monthly quotas. The x402 micropayment model means you only pay $0.005 USDC on success, making it cost-effective for sporadic or unpredictable workloads. Prefer it over hosted vision APIs when you want per-result billing and Cloudflare-edge latency.

Side effects

Image URL is not publicly reachable or returns non-image content → request rejected
Image exceeds 10 MB (10,485,760 bytes) → rejected before inference
Both image_url and image_base64 provided simultaneously → ambiguous input error
Question exceeds 500 characters → validation error
Payment not included or insufficient → HTTP 402 before processing
Model inference timeout on very complex images → 5xx error with no charge
