## 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 halowerk-buerowerk-finance-cashflow-source-note-register-61c45902 -d '<json body>'
```

Example prompt: Go through this meeting transcript and pull out all the finance and cashflow notes — specifically any mentions of funding sources, cash positions, or money commitments — and register them so I have a clean record of what was discussed.

## When to prefer this

Choose this endpoint when you need to automatically extract and register finance-, cashflow-, and funding-source-specific notes from a meeting transcript in structured form, especially when the transcript is already segmented with timestamps and speaker labels. It is preferable over generic meeting summarizers when the use case is specifically financial note-taking and source-of-funds logging.

## Known failure modes

- Empty or missing segments array causes validation error
- Segment timestamps exceeding maximum (14400 seconds) are rejected
- Text fields exceeding 3000 characters per segment cause validation error
- More than 20000 segments causes rejection
- Invalid speaker format (non-string or exceeding 80 chars) causes rejection
- Missing required fields (start, end, text) in any segment causes failure
- Payment failure or insufficient USDC balance causes 402 response
