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.
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.
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."
}
]
}'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.
