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' \

Limitations

Ambiguous dates need a format or locale hint
Ambiguous date formats (e.g., 01/02/03) are resolved using locale hints — may misinterpret month/day order without explicit format
What to do instead: Pass the expected date format or locale in the input to eliminate ambiguity for MM/DD vs DD/MM formats
