FLUX.1 [dev] text-to-image generation via fal.ai, pay-per-call over Tempo MPP
What it does
This endpoint wraps fal.ai's FLUX.1 [dev] model for high-quality text-to-image generation, exposed through the Tempo MPP (Micropayment Protocol) gateway at fal.mpp.tempo.xyz. FLUX.1 [dev] is a diffusion-based image generation model capable of producing detailed images from text prompts.
The endpoint is intended to accept a text prompt and return a generated image, settling payments in pathUSD on the Tempo L2 network. However, during probing the endpoint returned 404 on both HEAD and GET requests rather than the expected 402 MPP challenge. The root domain and all documentation paths also return 404. This suggests the endpoint may require a POST method, may have been moved, or may not currently be live.
Because no 402 challenge was captured, pricing details (amount, currency, decimals) are unknown. No OpenAPI schema, documentation, or examples were found at the crawled URLs. The underlying fal.ai FLUX.1 [dev] model is well-documented on fal.ai's own platform, but the MPP gateway layer provides no discoverable documentation at this time.
Capabilities
Use cases
- —Generating images from text prompts with per-call crypto micropayments
- —Integrating AI image generation into agent workflows without API keys or subscriptions
- —Producing high-quality illustrations or concept art on demand
Fit
Best for
- —Agents or apps that need pay-per-call image generation without traditional billing
- —Developers experimenting with crypto-settled AI inference
- —Users wanting FLUX.1 quality without a fal.ai account
Not for
- —Production workloads requiring guaranteed uptime — endpoint liveness is unconfirmed
- —Users needing detailed API documentation or SLA guarantees
Quick start
# Endpoint may require POST with a JSON body; 402 challenge not yet confirmed.
curl -X POST https://fal.mpp.tempo.xyz/fal-ai/flux/dev \
-H 'Content-Type: application/json' \
-d '{"prompt": "a cat sitting on a rainbow"}'Example
Request
{
"prompt": "a cat sitting on a rainbow",
"image_size": "landscape_4_3",
"guidance_scale": 3.5,
"num_inference_steps": 28
}Endpoint
Quality
The endpoint returned 404 on all probed methods and the entire crawled domain returns Not Found. No 402 MPP challenge was captured, no schema or documentation is available, and pricing is unknown. The listing is effectively a stub based on the Bazaar record title alone.
Warnings
- —Endpoint returned 404 on HEAD and GET — no MPP 402 challenge captured; liveness unconfirmed
- —Root domain and all documentation paths return 404
- —Pricing, schema, and supported HTTP methods are entirely unknown
- —Example request fields are inferred from public fal.ai FLUX.1 [dev] docs, not from this endpoint
