How to call it

The same tool through each route. MCP clients reach it through Strale’s server at https://api.strale.io/mcp; the call below is what the agent sends.

# Needs an API key. max_price_cents caps what this call may cost.
curl -X POST https://api.strale.io/v1/do \
  -H "Authorization: Bearer $STRALE_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{
    "capability_slug": "env-template-generate",
    "inputs": {

      "project_description": "This is a test input for automated capability testing."
    },
    "max_price_cents": 5

# No account. The first request answers 402 with the price in USDC;
# an x402 client pays it from your wallet and repeats the request.

Limitations

Dynamically named environment variables can be missed
Generates .env templates from code analysis — dynamically constructed environment variable names may be missed
What to do instead: Cross-reference with your deployment documentation to catch environment variables not referenced in code
