## 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 fundable-investor-search-dccabbe1 -d '<json body>'
```

Example prompt: Can you search Fundable for active investors focused on early-stage B2B SaaS startups based in the US, with a typical check size under $5M?

## When to prefer this

Use this endpoint when you need to discover multiple investors matching specific criteria such as stage, sector, geography, or check size — rather than looking up a single known investor by ID. Ideal for building investor lists for fundraising outreach or deal flow analysis.

## Known failure modes

- Invalid or unsupported filter parameters return a 400 error
- No investors match the given filters, returning an empty result set
- Rate limiting or authentication errors if API credentials are invalid
- Overly narrow filter combinations may return zero results

## How this service works

Search for investors using filters Pagination: page is 0-based (0, 1, 2, ...). Every page is a separate billable request priced on the results it returns. page_size (1-500) sets the maximum cost of a call.

## Output

A list of investor profiles matching the specified filters, including details such as investor names, firms, investment stage preferences, sector focus areas, geographic preferences, and check size ranges.
