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 google-gemini-file-upload-via-locus-x402-34192d5a -d '<json body>'
```

Example prompt: Upload this MP4 video from my S3 bucket — https://my-bucket.s3.amazonaws.com/meeting-recording.mp4 — to Gemini so I can ask it questions about the content; label it 'Q2 Meeting Recording'.

## When to prefer this

Use this endpoint when you need to stage a video file into Google Gemini before running multimodal analysis, vision queries, or reasoning tasks on it — especially when the source is an Amazon S3 URL (up to 100 MB) or a raw base64-encoded clip (up to 24 MB). Prefer the S3 URL path for larger files. This is distinct from Gemini chat or embedding endpoints; this is purely the file ingestion step in a multi-step Gemini workflow.

## Known failure modes

- Base64 payload exceeds 24 MB decoded limit — returns error indicating size constraint
- S3 URL exceeds 100 MB file size limit — rejected at ingestion
- Invalid or unsupported MIME type provided (must be video/mp4, video/quicktime, or video/webm) — returns validation error
- S3 URL is not publicly accessible or HTTPS — upload fails
- Payment authorization fails due to insufficient USDC balance — 402 payment required error
- Neither source_url nor data provided — missing required field error

## How this service works

Multimodal AI — chat, vision, PDF/document processing, thinking/reasoning, and embeddings.

## Output

A JSON response containing a file/data reference object, a unique request ID, a status URL to poll for completion, and payment settlement details showing the USDC amount charged and authorized — allowing the agent to subsequently reference the uploaded file in Gemini AI queries.
