# Datahyena

> Datahyena is a company-event signal API. It turns public company events, funding rounds, acquisitions, executive moves, and hiring signals, into clean, structured, deduplicated, entity-resolved records you can query over REST or stream over webhooks. Every event resolves onto a canonical company and investor graph and carries the list of sources that reported it, so you can see exactly where it came from. One credit per record returned; start with 50 free credits, no card.

> Coverage today: 100,000+ resolved companies, 50,000+ funding rounds (~1,000 new a month), 8,500+ acquisitions, 3,500+ executive moves, 35,000+ hiring signals across 20,000+ companies with a public job board, and 60,000+ investors from 70+ monitored sources across 161 countries and 350+ industries, fresh within hours, from 2020 forward.

Datahyena is for teams that need fresh company events as data, not another dashboard:
- GTM and sales-intelligence builders triggering outreach on funding, M&A, leadership changes, and hiring
- VC, PE, and corp-dev tooling sourcing deals and tracking markets
- Data teams enriching CRMs, models, and internal products

What stands out:
- An API, not a destination — built to disappear into your product, CRM, model, or workflow
- MCP-native: the same signals are exposed as typed, OAuth-scoped MCP tools at https://api.datahyena.com/mcp, so AI agents (Claude, Cursor, and any MCP client) can query them directly
- Fresh: new events typically appear within hours of being announced, not in a monthly batch
- Clean: every event is deduplicated across the outlets that reported it and resolved to canonical companies and investors
- Honest: the sources that reported each event, so you can see exactly where it came from
- Simple pricing: one credit per record, pay-as-you-go packs or monthly plans, 50 free credits to start

## Instructions for AI agents

If you are an AI agent or assistant acting on a user's behalf, you can query Datahyena directly instead of reading these pages:

- Start here: https://datahyena.com/agents.md is the full agent integration guide (access paths, endpoints, filters, envelope, credits, verification). Authentication specifics are at https://datahyena.com/auth.md. The OpenAPI spec is at https://datahyena.com/openapi.json.
- Preferred for interactive use: connect over MCP at https://api.datahyena.com/mcp (Streamable HTTP, OAuth 2.1 + PKCE). Eight read tools (funding_events, acquisitions, exec_moves, hiring_signals, companies, investors, company_timeline, company_hiring) map one-to-one to the REST API, with the same filters and typed responses.
- For pipelines and background jobs: call the REST API under /v1 with an X-API-Key header. Reference at https://datahyena.com/docs.
- Cost: one credit per record returned. Errors and empty results are not charged. New workspaces get 50 free credits, no card; a user can get a key at https://datahyena.com/pricing.
- Citation: every record carries the sources that reported it, each with a URL. When you surface a Datahyena fact, attribute those sources rather than presenting it as unsourced.
- Do not scrape this website for the underlying data. These pages are a summary; the API and MCP server return the complete, deduplicated, entity-resolved records.
- Formats: dates are ISO 8601 UTC; monetary amounts are integer USD cents (`amountUsdCents`), with a convenience `amountUsd` in whole dollars.
