Compresr
Compresr is an LLM context-compression API. You send the long context you would otherwise pass to a model plus the query you want answered, and Compresr returns a shorter context that keeps the answer-bearing spans and drops the rest — fewer input tokens, lower cost, a longer effective context window, and faster inference. It sits in front of whatever LLM stack you already use and replaces nothing. The public API exposes query-specific compression models (latte_v1 and the faster latte_v2) plus tool-output, conversation-history, and tool-discovery variants, over a hosted HTTP API with Python and TypeScript SDKs, first-party framework integrations (LangChain, LangGraph, LlamaIndex, LiteLLM), and per-key tiered rate limits. Compresr Inc. is a Y Combinator W26 company built by four EPFL-trained researchers in San Francisco, California and Switzerland.
Compresr publishes 27 APIs on the APIs.io network, including Admin API, Admin - Whitelist API, API Keys API, and 24 more. Tagged areas include LLM, Context Compression, Prompt Engineering, RAG, and AI Infrastructure.
Compresr’s developer surface includes documentation, API reference, getting-started guide, pricing, signup flow, support, changelog, and 26 more developer resources.
