Overview

The Halo API gives you access to official stats and metadata for Halo 5 and Halo Wars 2, including player profiles, match history, and game metadata. You need a free API key from the Halo Developer Portal to get started. It is a great choice for building stat trackers, leaderboards, or fan companion apps.

Beginner Tip

Register for a free subscription key at developer.haloapi.com and include it in the Ocp-Apim-Subscription-Key header with every request.

Available Data

The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.

Example Response

Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.

Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

Request
const url = "https://www.haloapi.com/metadata/h5/metadata/weapons";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "X-API-Key": "YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.

401 Unauthorized Missing or invalid subscription key in the request header.
Add the header Ocp-Apim-Subscription-Key: YOUR_API_KEY to your request.
429 Too Many Requests Exceeded the rate limit for your subscription tier.
Add delays between requests and consider upgrading your subscription tier for higher limits.
404 Not Found The specified player gamertag does not exist or the game title is incorrect.
Double-check the gamertag spelling and ensure you are using the correct game-specific endpoint.

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
