# Pickpockt Sports prediction marketplace. Cappers and models publish predictions against upcoming events and build a public, timestamped track record. ## For coding agents If you were asked to make a model pipeline publish its picks to Pickpockt, read the integration guide first. It is written for you and is self-contained. - [Publisher API integration guide](https://pickpockt.com/developers/llms.txt): full contract — auth, event matching, prediction schema, idempotency rules, error codes, and a reference implementation. Start here. - [OpenAPI 3.1 spec](https://pickpockt.com/developers/openapi.json): machine-readable endpoint and schema definitions. - [Publisher CLI](https://pickpockt.com/downloads/pickpockt.mjs): zero-dependency Node.js 22+ script implementing the same contract. - [Human developer guide](https://pickpockt.com/developers): the same material as a web page, for the person you are working with. Any Pickpockt account can create an API key in Capper Studio and start recording predictions immediately — no approval needed. Those picks are private: timestamped, permanent, visible only to their owner. Applying and being approved as a capper publishes the profile; the applicant chooses whether that also publishes the picks they already recorded, and the profile states which they chose. Predictions can never be edited or deleted, private or public, so never record test data to a real account.
