## How to call it through Zero

```sh
zero fetch --capability orthogonal-signalbase-acquisitions-c32a3941
```

Example prompt: Can you pull the latest acquisition signals from Orthogonal's SignalBase for US-based tech companies acquired in the last 30 days, with deal amounts between $5 million and $500 million, sorted by deal amount descending?

## When to prefer this

Use this endpoint when you need structured, filterable M&A acquisition deal data with rich company metadata including industry, geography, and deal size. It is ideal for business intelligence pipelines, competitive research, deal sourcing workflows, and monitoring acquisition activity in a specific market segment. Its pagination billing model makes it cost-efficient for multi-page queries on the same search. Prefer it over generic web scraping for M&A news when structured, queryable data is required.

## Known failure modes

- Invalid date_preset value returns a 400 validation error
- Unsupported currency ISO code may return no results or an error
- Exceeding max page limit (100) returns a validation error
- Changing filter parameters on a subsequent page starts a new billable request rather than continuing the prior one
- No results found for highly specific filter combinations returns an empty list

## How this service works

Fetch acquisition signals with filtering by date, country, deal amount, and company details. 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

Returns a paginated list of acquisition signal records, each containing the acquired company name, domain, industry, country, deal amount and currency, acquisition date, employee count, acquirer details, and category tags. Also includes pagination metadata and a billing requestId for free subsequent page calls on the same search.
