Developer platform

Ren API.

Integrate Astra into your engineering workflows. One stable HTTPS endpoint, authenticated with your Ren API key — no SDK to install, nothing else to wire up.

One endpoint

Simple by design.

Send an HTTPS request with your API key, set the model to astra, and start sending engineering tasks. No SDK to install, no base URL juggling.

request.sh● astra
curl https://api.ren.ai/v1/messages \
  -H "Authorization: Bearer $REN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "astra",
    "stream": true,
    "messages": [
      {
        "role": "user",
        "content": "Add cursor pagination to the activity feed and open a PR."
      }
    ]
  }'
On the roadmap

What the API will do.

The platform is in active development. These are the capabilities we are building toward — exposed as you would expect from a serious developer platform.

Repository Understanding

Reason over a connected codebase — architecture, dependencies, and conventions.

Code Generation

Produce changes consistent with the patterns already in the repository.

Architecture Analysis

Map how a system fits together and what a change will touch.

Pull Request Creation

Open reviewable pull requests as a programmatic operation.

Agent Workflows

Plan, run, and verify multi-step changes end to end.

Software Engineering Automation

Drive Ren Code from your own systems, metered per request.

Build with Astra.
