## 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 vaaya-signalbase-investors-database-b699edf3 -d '<json body>'
```

Example prompt: Search the Signalbase investors database for VC firms headquartered in the US with a minimum ticket size of $500,000 — return up to 50 results.

## When to prefer this

Use this endpoint when you need to discover, filter, or qualify investors across multiple fund types (VC, angel, PE, corporate, government, accelerator, family office, hedge fund, crowdfunding) in a single structured database. Prefer this over manual web research or unstructured search when you need filterable, machine-readable investor profiles for building fundraising target lists at scale.

## Known failure modes

- Invalid investor type enum value returns an error or empty results
- ticket_size_min greater than ticket_size_max causes empty or erroneous results
- limit exceeding 100 is rejected by the schema
- Overly broad search with no filters may return noisy or irrelevant results
- Payment failure (x402) results in no data returned

## How this service works

Signalbase — INVESTORS database: VC firms, angels, PE, corporate investors, government funds, accelerators, family offices, hedge funds, crowdfunding platforms. Filters: `type` (vc/angel/pe/corporate/government/accelerator/family_office/hedge_fund/crowdfunding), `search`, `headquarters`, `countries`, `ticket_size_min`/`max` (USD). `limit` ≤100 — flat price per call. Qualify funds and build investor target lists; pair with signalbase:funding (`investor_name`) to see a fund’s recent deals.

## Output

Returns a paginated list of investor records matching the specified filters, each containing details such as investor name, type (VC/angel/PE/etc.), headquarters, countries of focus, and ticket size range. Up to 100 records per call.
