How this service works
Run open-source AI models — image, video, audio.
Output
Returns a Replicate prediction object containing: a unique prediction ID, the model name, a status field (succeeded/failed/canceled/processing/starting), the generated image as a Replicate-hosted CDN URL (valid ~24 hours), timing metrics (total_time, predict_time in seconds), timestamps for creation and completion, and the USD cost charged for the call. On failure, an error string is returned instead of output.
Example use cases
Example prompt
“Generate an image of a misty Japanese forest at dawn with soft golden light filtering through bamboo trees, using FLUX 2 Flex on Replicate — pay the $0.74 per-call fee and give me the image URL when it's done.”
Technical details
Endpoint
POSThttps://replicate.payweave.services/models/black-forest-labs/flux-2-flex/predictionsWhen to prefer
Choose this endpoint when you need to run the FLUX 2 Flex model specifically, want pay-per-call pricing via x402 USDC micropayments without a subscription, or need access to Black Forest Labs' latest flexible image generation model through a Replicate-compatible API. Prefer over alternatives when working in x402-enabled agent pipelines or when the user explicitly needs FLUX 2 Flex output quality.
Side effects
- Model input validation error — missing or malformed 'input' object returns an error status
- Payment failure — insufficient USDC balance or x402 protocol error prevents call from completing
- Prediction timeout or cancellation — status returns 'canceled' or 'failed' with error message
- CDN URL expiry — image URLs are only valid ~24 hours after generation
- Model cold start — status may show 'starting' before transitioning to 'processing', increasing latency
