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": "commit-message-generate",
    "inputs": {
      "diff": "- const x = 1;\n+ const x = 2;\n  return x;"
    },
    "max_price_cents": 5
  }'

{
  "tool": "strale_execute",
  "arguments": {
    "slug": "commit-message-generate",
    "inputs": {
      "diff": "- const x = 1;\n+ const x = 2;\n  return x;"
    },
    "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: "commit-message-generate",
  inputs: {
    "diff": "- const x = 1;\n+ const x = 2;\n  return x;"
  },
  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="commit-message-generate",
    inputs={
        "diff": "- const x = 1;\n+ const x = 2;\n  return x;",
    },
    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/commit-message-generate?diff=-+const+x+%3D+1%3B%0A%2B+const+x+%3D+2%3B%0A++return+x%3B'

Limitations

Diffs alone may not explain the reason for a change
AI-generated messages based on diff content — may not capture the 'why' behind changes without additional context
What to do instead: Include a brief description of the intent in the input alongside the diff for more meaningful commit messages
