Grants

Grant indicators are available through:

• POST /indicators/grants/proofpoints
• POST /indicators/grants/time-series

What Is Different About Grants

Grants use project intervals (start_date, end_date) rather than publication dates.

• Use interval_overlap in query to filter projects by date overlap.
• For time series, provide start and end to define the chart window.
• time-series returns both project counts and amount (capital exposure) per bucket.

Typical Questions

• Which grants are active in this topic and period?
• Is active project volume increasing or declining across the chosen window?
• How much total project capital is exposed month-by-month?

Request Patterns

Proofpoints

Use the same nested query style as other document indicators, but with interval_overlap for project dates.

{
  "query": {
    "type": "and",
    "clauses": [
      {
        "type": "query",
        "query": "battery recycling"
      },
      {
        "type": "interval_overlap",
        "start": "2022-01-01",
        "end": "2024-12-31"
      }
    ]
  },
  "take": 25,
  "skip": 0,
  "sortColumn": "published_at",
  "sortDirection": "desc"
}

Time Series

start and end define bucket generation for the output series.

{
  "resolution": "month",
  "start": "2022-01-01",
  "end": "2024-12-31",
  "query": {
    "type": "interval_overlap",
    "start": "2022-01-01",
    "end": "2024-12-31"
  }
}

Response Notes

• labels: bucket labels at the selected resolution.
• counts: number of active overlapping projects in each bucket.
• amount: rounded, time-weighted capital exposure per bucket.
  • Uses project total_cost.
  • Falls back to cordis_ec_contribution when total_cost is missing or 0.

Validation Notes

• DateFilter is not supported for grants. Use interval_overlap instead.
• start must be on or before end.
• Score-weighted time series options are not supported on grant time series.
