What Is origin_key?

Learn what origin_key means in growthepie and where to find valid origin_key values.

origin_key is the canonical growthepie identifier for a covered entity, most commonly a chain. You use origin_key values such as arbitrum, base, ethereum, or zksync_era to filter flat exports and to address richer endpoints such as chains/{origin_key}/overview.json.

Where do I get valid origin_key values?

Use master.json. Each chain entry in master.json.chains includes metadata and supported metrics.
