Model APIs and gateways · by Cohesor, Inc.

Cohesor

A hosted gateway that sits between your agents and model providers: it accepts Anthropic- or OpenAI-style requests at one base URL, compresses prompts, sends simple requests to cheaper models, enforces per-user budgets and exposes a governed MCP endpoint for GitHub, Google, Slack and Postgres tools.

You can cut and cap agent model spend by swapping one base URL and key instead of rewriting code for each provider.

For your agent

  • No SDK: set ANTHROPIC_BASE_URL=https://api.cohesor.com with ANTHROPIC_AUTH_TOKEN=sk-coh-..., or OPENAI_BASE_URL=https://api.cohesor.com/v1 with OPENAI_API_KEY=sk-coh-...; the MCP gateway is https://api.cohesor.com/mcp with header x-api-key.
  • Gateway keys (sk-coh-) are shown once; keep them out of code and repos
  • Upstream model providers' terms and content policies still apply to outputs
  • Compression can change prompt bytes; pin a fixed model or turn routing sensitivity down for tasks that need exact behaviour

What you can build

  • Route a team's Claude Code and Codex traffic through one key with per-developer budget caps
  • Add a cost dashboard to an agent product by reading per-request spend from the gateway instead of each provider
  • Give an internal support agent governed GitHub and Google Drive tools through one MCP endpoint
