Jentic publishes the only available OpenAPI document for Crunchbase API, keeping it validated and agent-ready.

Jentic publishes the only available OpenAPI specification for Crunchbase API, keeping it validated and agent-ready. Crunchbase is the canonical dataset of private companies, funding rounds, acquisitions, and people in the global startup ecosystem. The API exposes nine endpoints across search, autocomplete, and entity retrieval covering organizations, people, funding rounds, and acquisitions. Authentication uses an API key passed as the user_key query parameter against the https://api.crunchbase.com/api/v4 base URL.

Use Cases

Patterns agents use Crunchbase API API for, with concrete tasks.

★ Outbound Sales Prospecting

Build a target account list of recently funded companies with structured filters instead of scraping news. POST /searches/organizations supports filters by funding stage, industry, geography, and date, and GET /entities/organizations/{entity_id} returns the full company profile for downstream CRM enrichment. Suitable for sales teams targeting venture-backed companies.

Search organizations matching 'Series B' funding stage in 'fintech' from the last 12 months, then retrieve full profiles for the top 25 results.

Investor and Acquisition Tracking

Track a specific investor's portfolio activity or watch acquisitions in a sector. POST /searches/funding_rounds and POST /searches/acquisitions accept investor and acquirer filters, and the matching GET endpoints return full deal records. Useful for venture analysts, M and A teams, and investor-relations functions.

Search funding rounds led by a target investor in the last 90 days, then retrieve each round entity and produce a markdown digest grouped by industry.

CRM Account Enrichment

Enrich CRM company records with Crunchbase firmographics and funding history at sync time. GET /entities/organizations/{entity_id} returns the canonical record for an org, and POST /searches/organizations resolves company name and domain to an entity. Useful for sales operations teams keeping Salesforce or HubSpot accounts current.

For each company domain in the CRM nightly sync, search organizations to resolve the entity ID and pull the full GET /entities/organizations/{entity_id} record into the CRM custom fields.

Founder and Executive Research

Research founders or executives by querying Crunchbase people records and joining them with their organization affiliations. POST /searches/people accepts role and organization filters, and GET /entities/people/{entity_id} returns the full profile. Useful for executive recruiting, journalism, and competitive research.

Search people with role 'Founder' at organizations in 'climate tech' and return the top 20 person entity records.

Agent-Driven Market Research via Jentic

AI agents that produce competitive briefs, deal sheets, or sourcing lists can call Crunchbase through Jentic without holding the user_key. The agent searches Jentic for the relevant intent, loads the schema, and runs the search or entity lookup with the key held in Jentic's vault. This keeps the Crunchbase subscription credential isolated from the agent's prompt context.

Use Jentic to search 'search crunchbase organizations', load POST /searches/organizations, and execute it with the user's industry and funding-stage filters.

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Crunchbase user_key values sit encrypted in the Jentic vault and are appended to outbound requests as the user_key query parameter. The raw key never enters the agent's context.

Intent-based discovery

Agents search by intent (e.g. 'search crunchbase organizations') and Jentic returns the matching POST /searches/organizations operation with its input schema, so the agent calls the right endpoint without browsing data.crunchbase.com/docs.

Time to first call

Direct Crunchbase integration: 2-4 days including data licence setup, search-filter modelling, and entity record handling. Through Jentic: under 1 hour — Crunchbase data licence still required separately.

FAQs

Specific to using Crunchbase API API through Jentic.

Why is there no official OpenAPI spec for Crunchbase API?

Crunchbase publishes only descriptive documentation. Jentic generates and maintains this OpenAPI specification so that AI agents and developers can call Crunchbase API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the Crunchbase API use?

The Crunchbase API uses an API key passed as the user_key query parameter on every request. Through Jentic the user_key is held in the vault and appended to outbound requests so it never enters the agent's context.
