Bug: Corporation Contract Items Error 420 (now 520)

[GoldenGnu]

Bug

I'm having problems updating all corporation contract items for eve university.
There is currently around 900 contracts that have contract items (I'm not trying to update contracts that does not have items), I'm updating 100 at the time.
After a few seconds of running the updates, I get the error described bellow.

I tried updating them one at the time, but, it still fails after calling the corporation contract items endpoint around 450-680 times. None of the previous requests failed, they where all completed successful and all returned contract items (none of request had empty results).

Request

https://esi.tech.ccp.is/latest/#!/Contracts/get_corporations_corporation_id_contracts_contract_id_items
Reproduced with Golden Gnu

Response

420

{"error":"{'error_label': 'ConStopSpamming', 'error_dict': {'remainingTime': 82647325L}}"}

Expected

Contract Items for the selected contracts

So unfortunately it looks like you've rubbed up against an internal throttling that is being exposed through ESI. The way it works is you can make 20 requests per 10 seconds for a contract tied to a specific character ID. In this case, it would be whatever character is tied to the SSO token. 82647325L would mean you have about 8 seconds remaining on your throttle.

I tell you these details so you can work around it for now. Not ideal, but at least you know the rules until I can come back and revisit this after parity ™️

Internal monolith 420 errors have now been changed to 520 and the documentation for this endpoint has been updated to say as much. The way these represented will not be changed in the near future so I'm closing this issue.

Does the 520 rate limit include requests made by that character in game in the same time period? I'm consistently getting 520s pulling just a couple of corp contracts with no other requests or errors made in a 10 minute window.

This issue should probably be re-opened, it's not really fixed just kludged. At least adding the 20/10 limit to the description or even linking to this issue would be helpful.
