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": "dangerous-goods-classify",
    "inputs": {
      "substance": "acid"
    },

  }'

# 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

Classification requires certified confirmation
AI-based classification guidance — official dangerous goods classification requires certified testing and documentation
What to do instead: Use as a preliminary screen and confirm the UN number and packing group with your certified DG adviser
