# FLUX.2 \[pro\] outpaint

Needs image url. Served by fal.ai.

FLUX.2 [pro] (Black Forest Labs), outpaint, served by fal.ai. The OpenAPI schema for the fal-ai/flux-2-pro/outpaint queue. Price: $0.03 for the first megapixel of output plus $0.015 per extra megapixel of input and output, rounded up to the megapixel, metered by fal after the call (x-fal-billable-units) and billed at that reading; the reservation is the bound you declare and the difference is refunded. Waits up to 40 s for the result; if the generation takes longer, the run stays RUNNING and returns a request_id; poll fal/status and fetch fal/result with model "fal-ai/flux-2-pro" and that request_id. Billed once, when the result is ready; a generation that fails is refunded.

## Published example

This is the provider tool’s published example. Replace example values with the user’s requested inputs, respecting the schema; do not execute an example merely to test a connection.

## Execute and retrieve

Inspect again before execution, explain the price and obtain the required authority. Use MCP run_tool or POST /v1/run with this tool ID, valid input and an idempotency key. Save the returned run ID and follow the actual state. If Agentik answers that the tool is temporarily unavailable, do not retry it blindly; use discovery to propose an alternative.

This tool uses deferred settlement. Follow its returned task/run instructions; preserve the existing reservation until the result is reconciled.

A partial or uncertain result can still have consumed provider resources. Consult [billing](/docs/billing.md), [idempotency](/docs/idempotency.md) and [asynchronous results](/docs/async.md).
