# Flux 3 draft enhance

Needs draft cache url. Served by fal.ai.

Flux 3 Draft Enhance, served by fal.ai. The OpenAPI schema for the blackforestlabs/flux-3/draft-enhance queue. Price: Your request will be charged at 0.29 $ per second of the enhanced video (full-quality 1080p render). Synchronized audio is included at no extra cost. Actual-cost billing: the initial reservation is an estimate, not a maximum. 5 seconds of full-quality 1080p enhancement at $0.29/s; actual draft duration affects cost. The unique Billing Events receipt for this exact endpoint and request_id is the final USD charge, including usage above the estimate. Missing receipts retain the reservation for reconciliation; no guessed final fee. Asynchronous: returns a request_id; poll fal/status and fetch fal/result with model "blackforestlabs/flux-3" 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).
