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": "csv-to-json",
    "inputs": {
      "csv_string": "test_value"
    },
    "max_price_cents": 2
  }'

{
  "tool": "strale_execute",
  "arguments": {
    "slug": "csv-to-json",
    "inputs": {
      "csv_string": "test_value"
    },
    "max_price_cents": 2
  }
}

import { Strale } from "straleio";

const strale = new Strale({ apiKey: process.env.STRALE_API_KEY! });
const result = await strale.do({
  capability_slug: "csv-to-json",
  inputs: {
    "csv_string": "test_value"
  },
  max_price_cents: 2,
});

import os
from straleio import Strale, DoRequest

strale = Strale(api_key=os.environ["STRALE_API_KEY"])
result = strale.do(DoRequest(
    capability_slug="csv-to-json",
    inputs={
        "csv_string": "test_value",
    },
    max_price_cents=2,
))

# 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/csv-to-json?csv_string=test_value'

Limitations

Mixed delimiters or multiline cells can cause errors
Expects well-formed CSV with consistent column counts — multi-line cell values or mixed delimiters may cause parse errors
What to do instead: Pre-clean the CSV with csv-clean before converting, or specify the delimiter explicitly
