# Datahyena

> Datahyena is a growth-signals API. It turns public B2B business events — funding rounds, acquisitions, and executive moves — into clean, structured, deduplicated, entity-resolved records you can query over REST or stream over webhooks. Every event 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.

Datahyena is for teams that need fresh growth signals as data, not another dashboard:
- GTM and sales-intelligence builders triggering outreach on funding, M&A, and leadership changes
- 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:

- Preferred for interactive use: connect over MCP at https://api.datahyena.com/mcp (Streamable HTTP, OAuth 2.1 + PKCE). Five read tools — funding_events, acquisitions, exec_moves, companies, investors — 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 in USD.
