Projects

Project proof points replace the deprecated grants indicator. Each record is an indexed project (for example CORDIS) with status, program, dates, and cost fields.

Endpoints:

• POST /proof-points/projects/search — playground
• POST /proof-points/projects/time-series — playground
• POST /proof-points/projects/correlation-matrix — playground

What changed from grants

The old grants API used nested interval_overlap on project start/end. On these endpoints, start and end are published-date bounds, the same as other proof points. Project interval fields (startDate, endDate) are still returned on each record so you can apply interval logic in your client.

Typical Questions

• Which grant projects are tied to this topic?
• Is project volume increasing across the chosen window?
• How much capital (totalCost / cordisEcContribution) is associated with matching projects?

Type-specific filters

On top of the shared proof-point fields:

• statuses — for example ongoing or closed
• acronyms
• programs — fp7, horizon_2020, horizon_europe
• cordisGrantDois

Response Notes

Each project can include status, acronym, program, startDate, endDate, totalCost, cordisEcContribution, and cordisGrantDoi. Time series returns labels and counts (and amount when capital is aggregated).
