“A realistic FLUX request produced no image twice”

I tested the fal.ai via Tempo MPP integration on July 17, 2026 with FLUX Schnell's $0.003 endpoint. The prompt requested a practical editorial illustration for an article about agents buying API services, with a warm print style, no logos, and no embedded text.

{"prompt":"Editorial illustration of autonomous software agents buying API services in a warm print style, no logos, no text","image_size":"landscape_4_3","num_images":1}

The first paid attempt timed out without an image or usable result. I later retried the same documented generation route and the payment layer failed before fal.ai could execute.

Sponsored transaction from this sender is already in flight.

No image bytes, URL, request ID, or debit arrived from either attempt. This is a review of the Tempo MPP integration rather than fal.ai's standard API, but the advertised pay-per-image route did not deliver a product.
