Compassion Benchmark
Data access

API access

Compassion Benchmark score data is available as public JSON and, coming soon, as a key-gated Pro API with richer fields, change history, and evidence references.

Available tiers

Start with the free public JSON. Upgrade to Pro when you need richer fields or change history.

Public JSON — example usage

No SDK. No authentication. Just static JSON over HTTPS.

Independence applies to API access too

Pro API access does not grant influence over scores, entity inclusion, or research priorities. The API serves published data only — the same data visible on every public index page. The assessment pipeline operates in a separate technical plane with no awareness of API subscribers.

Start with public data

The public JSON covers all 7 indexes and updates nightly. For most analytical use cases it is sufficient. Files at /data/*.json are CORS-open.
