Endpoint
GEThttps://api.messari.io/funding/v1/projectsWhen to prefer
Use this endpoint when you need to discover or enumerate crypto projects with structured metadata (sector, category, founding date) and want to filter them programmatically.

Best for research workflows that need to cross-reference projects with fundraising or investor data from sibling endpoints.

- Malformed date strings for foundedAfter/foundedBefore may return 400 errors
