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": "barcode-lookup",
    "inputs": {
      "barcode": "3017620422003"
    },
    "max_price_cents": 5
  }'

{
  "tool": "strale_execute",
  "arguments": {
    "slug": "barcode-lookup",
    "inputs": {
      "barcode": "3017620422003"
    },
    "max_price_cents": 5
  }
}

import { Strale } from "straleio";

const strale = new Strale({ apiKey: process.env.STRALE_API_KEY! });
const result = await strale.do({
  capability_slug: "barcode-lookup",
  inputs: {
    "barcode": "3017620422003"
  },
  max_price_cents: 5,
});

import os
from straleio import Strale, DoRequest

strale = Strale(api_key=os.environ["STRALE_API_KEY"])
result = strale.do(DoRequest(
    capability_slug="barcode-lookup",
    inputs={
        "barcode": "3017620422003",
    },
    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.
curl -i 'https://api.strale.io/x402/v2/barcode-lookup?barcode=3017620422003'

Limitations

Coverage is strongest for food and drink
Product database via Open Food Facts — coverage strongest for food/beverage products, weaker for electronics and general merchandise
What to do instead: Check the barcode with the manufacturer or retailer if no product is found.
