Agent Metadata
Known Gotchas
- ⚠ Template layer names must exactly match the modification keys sent in the API payload; typos silently produce unmodified output
- ⚠ Async renders require polling or webhook setup; synchronous mode has stricter rate limits
- ⚠ Image URLs passed as layer values must be publicly accessible; private or auth-gated URLs will fail silently
- ⚠ Video generation has significantly longer render times (30+ seconds) versus image generation (1-3 seconds)
- ⚠ Free trial credits expire; agents must handle 402 Payment Required errors gracefully
