GET /credits

Total granted and total used

Returns how much credit has ever entered the account and how much has left it. Both figures are in Korean won (KRW).

GET https://openrouter.myip.co.kr/api/v1/credits

Authentication

Authorization: Bearer <key> is required. Both key kinds are accepted — inference and management. Credit belongs to the account rather than to a key, so any key on the account gives the same answer.

/api/v1 does not accept cookies. A logged-in browser showing a balance uses the session cookie against /api/dashboard/credits instead.

Request parameters

None. The endpoint takes no query parameters and no body.

Request example

curl https://openrouter.myip.co.kr/api/v1/credits \
  -H "Authorization: Bearer $MYIP_API_KEY"

Response

total_creditsnumber

Sum of credit granted to the account, in won: the ledger's charge (paid top-ups) and bonus entries added together. It is a monotonically increasing total, not the current balance.

total_usagenumber

Sum of money that has left the account, in won: the absolute values of the ledger's deduct (usage) and expire entries. Also cumulative, so it never decreases. It is significant to six decimal places, because a single call often costs less than one won.

Getting a balance from this

balance ≈ total_credits - total_usage

When the numbers move

Right after a top-up: total_credits rises as soon as the payment is approved.
Right after a call: total_usage is settled after the response is sent, so there is a short delay. A call that has just finished may not be reflected yet.
Streaming: settlement happens when the stream ends ([DONE], or the connection closing).

If you need the exact cost of one call immediately, do not poll this endpoint. Use usage.cost in a non-streaming response, the X-MyIP-Cost-KRW response header, or the usage chunk in a stream. For an authoritative figure after the fact, use GET /generation.

Per-key spend

This endpoint is account-wide. To see what a single key has spent, read usage, usage_daily, usage_weekly and usage_monthly from GET /key. The spend of all keys on an account adds up to total_usage.
