ModelRaters Open Telemetry API Explorer

👋 Welcome to the Open Telemetry API

Don't worry, it's not broken!

If you clicked a link like /v1/leaderboard.json and saw a wall of raw brackets and text, that's completely normal! That format is called JSON (JavaScript Object Notation), and it's how software applications, Python scripts, and AI agents "talk" to each other without human interface lag.

The Scoreboard Analogy: Think of this endpoint like an automated sports scoreboard wire. Instead of a human opening a browser to look at a webpage, your code can pull down the exact real-time rankings, ELO scores, fuel prices, and porosity ratings across all 10,858 AI engines with a single command.

Run this in Python to query the leaderboard directly:

import requests

# Fetch the live ModelRater leaderboard
data = requests.get('https://modelraters.com/v1/leaderboard.json').json()
leaderboard = data['leaderboard']

print(f"Total engines tracked: {len(leaderboard):,}")
print(f"Rank #1: {leaderboard[0]['name']} | Dyno Score: {leaderboard[0]['empirical_score']}/100")

Fetch in modern JavaScript / Node.js:

const res = await fetch('https://modelraters.com/v1/leaderboard.json');
const data = await res.json();

console.log(`Loaded ${data.leaderboard.length} models!`);
console.log(`Top Model: ${data.leaderboard[0].name} (${data.leaderboard[0].dossier_id})`);

Command line terminal query with jq:

curl -s https://modelraters.com/v1/leaderboard.json | jq '.leaderboard[0:5][] | {rank, name, empirical_score, coding_elo}'

Import live telemetry directly into your spreadsheet:

=IMPORTDATA("https://modelraters.com/v1/leaderboard.json")
