## 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 www-miniup-io-015b7cdd -d '<json body>'
```

Example prompt: Give me a presigned upload URL for my MiniUp app (site ID: abc123) so I can upload a CSV data file.

## When to prefer this

Use this endpoint when you need to upload a raw data file (CSV, XLSX, JSON, GeoJSON, Shapefile ZIP, Parquet, or GeoParquet) to a MiniUp app as the first step before converting it into a queryable dataset. Prefer this over the multipart upload endpoint for single-part file uploads, and use it before calling the conversion endpoint to turn the file into a parquet-backed API dataset.

## Known failure modes

- Invalid or non-existent siteId returns a 404 or authorization error
- Unsupported file type results in a validation error
- Paying wallet does not own the specified app, returning an authorization/ownership error
- Expired presigned URL if not used within the validity window
- Payment failure or insufficient USDC balance blocks the request
