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 '{

Limitations

Binary and multipart requests may need manual adjustment
Converts standard HTTP request formats — binary payloads or multipart uploads may produce simplified curl equivalents
What to do instead: For binary payloads, use the --data-binary flag manually and reference the file path instead of inline content
