Returns up to 15 results per request with the total count matching your filters. ## Quickstart ``` GET https://api.piloterr.com/v2/crunchbase/funding_rounds?days_since_announcement=1 GET https://api.piloterr.com/v2/crunchbase/funding_rounds?days_since_announcement=30&investment_type=seed ``` ## Parameters | Parameter | Type | Required | Description | |---|---|---|---| | `days_since_announcement` | integer | no | Number of days since announcement (1–360, default: `1`) | | `investment_type` | string | no | Filter by round type (e.g. `seed`, `series_a`, `series_b`) | | `investor_identifiers` | string | no | UUID of a specific investor to filter by | | `funded_organization_identifier` | string | no | UUID of the funded organization to filter by | ## Response fields | Field | Type | Description | |---|---|---| | `total` | number | Total number of results matching filters (may exceed 15) | | `results[].uuid` | string | Unique identifier of the funding round | | `results[].investment_type` | string | Type of investment | | `results[].identifier.permalink` | string | Crunchbase permalink of the round | | `results[].identifier.value` | string | Human-readable round label | | `results[].funded_organization_identifier.value` | string | Name of the funded company | | `results[].funded_organization_identifier.uuid` | string | UUID of the funded company | | `results[].investor_identifiers` | array | List of investors (may be empty if not publicly disclosed) | ## Notes - **Maximum 15 results per request.** If `total > 15`, split requests by `investment_type` to cover all rounds. - `investor_identifiers` in results may be an empty array for rounds where investors are not publicly disclosed. - Since 2026, Crunchbase may withhold additional fields on recent rounds as an upstream policy change (anti-LLM/scraping). The API remains fully operational: sparse responses reflect Crunchbase's reduced disclosure, not a Piloterr outage. - Combine `days_since_announcement` with `investment_type` to build a comprehensive funding monitor. ## Main use cases - Monitor daily or weekly funding announcements to identify newly funded companies for outreach - Track which investors are most active in specific round types (e.g. seed rounds in the last 7 days) - Build automated funding alerts that trigger sales or marketing workflows when target companies raise - Aggregate multi-type funding data by iterating across investment types for complete market coverage
