The ESI contains a lot of data, much of which takes a long time to fetch if you want all of it.
A number of ESI exports are available, maintained by third parties:
- Fuzzwork Market API contains regular scrapes of all market orders.
- EVE Ref Data contains a number of ESI scrapes, including:
- Game world data, which can be used to complement the SDE.
- Market history past one year, where the ESI itself only provides a year.
- Market orders.
- Public contracts.
