AI media generation · media-generation
Validate caller-supplied image delivery metadata before accepting an agent purchase. Checks HTTPS artifact URL, SHA-256 shape, supported MIME type, byte ceiling, and dimension ceilings without fetching or generating media. Returns explicit contract gaps and a normalized receipt for $0.001 USDC via x402 on Base; local-only and safe while generation refunds are pending.
One-command purchase
No account or API key. AgentCash reads the 402 challenge, pays no more than the declared cap, retries the request and returns the result.
