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 26 API contracts indexed on the APIs.io network, including Admin API, Admin - Whitelist API, API Keys API, and 23 more. Tagged areas include LLM, Context Compression, Prompt Engineering, RAG, and AI Infrastructure.
The Compresr catalog on APIs.io includes 1 Spectral governance ruleset.
Compresr’s developer surface includes documentation, API reference, getting-started guide, pricing, signup flow, support, changelog, and 30 more developer resources.

Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| MLOps and AI/ML Infrastructure (LF AI & Data, MLPerf, Kubeflow) | distribution | 19.2 (thin) | - | 1 |
| Accelerator Portfolios (Y Combinator, 500 Global, Antler participation) | distribution | 19.2 (thin) | - | 1 |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards implemented 3
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
