## 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 orthogonal-signalbase-funding-signals-91c59b9e
```

Example prompt: Find me all Series A and Series B funding rounds in the US fintech industry from the last 30 days, with amounts between $5M and $100M — show me up to 50 results sorted by date.

## When to prefer this

Use this endpoint when you need structured, filterable startup and company funding round data with precise controls over date range, geography, round type, and funding amount. It is especially well-suited for sales intelligence, market research, investor tracking, and competitive monitoring workflows that require pagination over large result sets with cost-efficient continuation billing via parentRequestId.

## Known failure modes

- Invalid ISO-8601 date format returns a 400 error
- Unknown or misspelled industry/category values may return empty results
- Changing filter parameters while passing parentRequestId starts a new billable request
- Exceeding max limit of 100 per page returns a validation error
- Invalid currency code (non-ISO 4217) causes a 400 error
- Rate limiting or payment failure returns a 402 or 429 error

## How this service works

Fetch funding signals with filtering by date, country, round type, amount, industry, and more. Pagination billing: call the first page normally and save billing.requestId from the Orthogonal /v1/run response. For later page, offset, or cursor calls on the same logical search, pass parentRequestId with unchanged non-pagination parameters. Valid continuation calls still get their own request IDs and quoted price, but are charged 0. Changing filters starts a new billable request.

## Output

A paginated list of funding signal records, each containing company name, funding round type, amount, currency, date, country, industry, and related metadata. The response includes billing information with a requestId that can be used as parentRequestId for free subsequent pages of the same query.
