## 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-8b2a2af9 -d '<json body>'
```

Example prompt: I've finished uploading all parts of my large CSV file to my MiniUp app — can you complete the multipart upload for site ID 'site_abc123' so I can convert it into a dataset?

## When to prefer this

Use this endpoint after initiating a multipart data file upload via the MiniUp presigned upload URL endpoint and uploading all file parts. This is a required intermediate step before calling the data-file conversion endpoint to turn the uploaded file into a queryable MiniUp dataset. Choose this when handling large data files that required chunked/multipart upload rather than single-part uploads.

## Known failure modes

- Invalid or unknown siteId returns a 404 error
- Missing or malformed upload ID causes a 400 bad request
- Wallet does not own the specified site, resulting in a 403 unauthorized
- Upload parts are incomplete or missing, causing finalization to fail
- Attempting to complete an already-completed or expired upload returns an error
- Network timeout during finalization leaves the upload in an indeterminate state

## How this service works

Complete a multipart data-file upload before conversion.

## Output

A confirmation that the multipart data file upload has been finalized and the file is now ready for conversion into a MiniUp parquet-backed API dataset, including the resulting data file record or status.
