# Transactions

> Funding rounds, acquisitions and IPOs each with a stable ID and both sides of the deal resolvable

Funding rounds, acquisitions, and IPOs across 1M+ global transactions. Specter's transactions dataset captures deal activity across private and public markets. Each transaction has a stable ID (`fnr_`, `acq_`, `ipo_`) and links directly to the companies and investors involved.

## Data categories

* **Funding rounds** — `investment_type` (Seed through Series J, plus Undisclosed), `raised_amount_usd`, `announced_on`, pre- and post-money valuations, and the full `investors` list with an `is_lead_investor` flag.
* **Acquisitions** — both sides of the deal (`acquirer_company_id` / `acquiree_company_id` with names and domains), `acquisition_type` (acquisition, merge, lbo, acquihire, management\_buyout), `price_usd`, `acquisition_date`.
* **IPOs** — issuing company, exchange, ticker, pricing, and capital raised.
* **Participants** — investors and companies, resolvable to full profiles via their IDs.

## How to use the API

**Start with what you have**

* A company → [Get company funding rounds](/api-reference/companies/get-company-funding-rounds), [Get company acquisitions](/api-reference/companies/get-company-acquisitions), or [Get company IPOs](/api-reference/companies/get-company-ipos).
* An investor → [Get investor funding rounds](/api-reference/investors/get-investor-funding-rounds).
* A transaction ID → [Get funding round by ID](/api-reference/transactions/get-funding-round-by-id) (`fnr_`), [Get acquisition by ID](/api-reference/transactions/get-acquisition-by-id) (`acq_`), or [Get IPO by ID](/api-reference/transactions/get-ipo-by-id) (`ipo_`).

**Expand from a transaction**

* Funding round → each investor's `investor_id` → [Get investor by ID](/api-reference/investors/get-investor-by-id).
* Acquisition → `acquirer_company_id` or `acquiree_company_id` → [Get company by ID](/api-reference/companies/get-company-by-id).
* IPO → issuing company → [Get company by ID](/api-reference/companies/get-company-by-id).

## Notes

* Transaction data is usually reached via a company or an investor, then drilled into by transaction ID.
* Deal terms (amount, valuation) are null when undisclosed — never 0.
* Funding rounds carry the full investor list with a lead flag (`is_lead_investor`); acquisitions carry both the acquirer and acquiree company IDs.
* Transaction IDs are prefixed (`fnr_`, `acq_`, `ipo_`); the company and investor IDs inside them chain to the Companies and Investors APIs.
