# Vaaya FAL Upload

> Vaaya FAL Upload is a paid API for AI agents from vaaya.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Upload a file to FAL (a media/ML inference platform) via the Vaaya proxy, returning a hosted URL usable in subsequent AI media generation or processing calls.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability vaaya-fal-upload-69d5dec6 -d '<json body>'
```

Example prompt: Upload this image file to FAL through Vaaya so I can use the hosted URL in my next image-to-image generation step.

## When to prefer this

Use this endpoint when you need to make a locally held or agent-accessible file available at a publicly reachable FAL URL before passing it into a fal.ai model inference call. It is the correct pre-step for any fal.ai workflow that requires a URL input rather than accepting raw binary data directly. Prefer this over generic storage services when the downstream consumer is specifically a fal.ai model.

## Known failure modes

- File too large — FAL upload size limits may cause rejection
- Unsupported file format — FAL may not accept certain MIME types
- Network timeout on large file uploads
- Invalid or missing file body in POST request
- Upstream FAL service unavailable causing proxy failure

## How this service works

Stage a media file on the fal CDN before a fal generation. Returns { upload_url, file_url }: PUT the raw file bytes to upload_url (with the matching Content-Type header), then pass file_url as the image_url/video_url/audio_url param of the generation. Upload originals UNCOMPRESSED — never downscale or re-encode; high-res inputs cost nothing extra and compression degrades outputs.

## Output

A hosted FAL asset URL pointing to the uploaded file, which can be passed directly as an input parameter to fal.ai model inference endpoints for image-to-image, inpainting, upscaling, or other media generation workflows.
