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.

# No account. The first request answers 402 with the price in USDC;

Limitations

Severely malformed CSV may need manual preparation
Handles common CSV issues (encoding, delimiters, quoting) — extremely malformed files may require manual preprocessing
What to do instead: If cleaning fails, specify the exact delimiter and encoding in the input parameters
