This API has been retired. The hosted endpoints at api.bestinslot.xyz are no longer operated, and new API keys are not being issued.Run OPI (Open Protocol Indexer) instead — our open-source, self-hosted indexer for BRC-20, Bitmap and SNS, with a REST API per module. See the introduction for what it covers and what you need to run it.The pages below are kept online for historical reference only.

​
Rate Limiting

There were 4 API-Key categories: Basic, Pro, Enterprise and Dedicated. Some endpoints were only available in some plans. Free plan and trial keys were rate limited with daily limits, all other plans used monthly limits. New API keys are no longer issued. Endpoints’ API-Key-Tier availabilities are written for each endpoint in documentation. Expired API-Keys automatically turn into Free-Tier API Key.

​
General Usage Information
