title: Token Company Compression API
version: '1.0'
description: LLM input compression middleware. One API call removes low-signal tokens from a prompt, a chat conversation, or web-search results before they reach a language model, cutting cost and latency while preserving output quality. Compression is performed by the bear family of models (bear-2 latest, bear-1.2 / bear-1.1 / bear-1 previous generations).

method: generated
note: Faithfully reconstructed from the official Python SDK source (github.com/TheTokenCompany/the-token-company-python) and the public documentation at https://thetokencompany.com/docs. The provider does not publish an OpenAPI document; the API itself is invite-only. No behavior, field, endpoint, or error was invented.
