The Coinbell API

Quick start

1. Create a key here (you need a free account).
2. Send it in the x-api-key header with every request.
3. Every answer is JSON inside data.

curl -H "x-api-key: YOUR_KEY" https://coinbell.org/v1/p2p/lkr

Base URL: https://coinbell.org/v1. Read-only, HTTPS only, CORS open so it works from the browser too (but keep your key out of public pages).

JavaScript

const res = await fetch('https://coinbell.org/v1/markets?limit=10', {
  headers: { 'x-api-key': 'YOUR_KEY' },
});
const { data } = await res.json();
console.log(data.coins.map((c) => `${c.symbol}: $${c.price}`));

Python

import requests

r = requests.get("https://coinbell.org/v1/usdt-premium",
                 headers={"x-api-key": "YOUR_KEY"}, timeout=10)
for row in r.json()["data"]["rows"]:
    print(row["code"], round(row["premium"] or 0, 2), "%")

Response format

{
  "data": { ... },
  "attribution": "Data from Coinbell (https://coinbell.org)",
  "plan": "free"
}

Errors come back as { "error": "…" } with a normal HTTP status: 400 bad input, 401 missing or wrong key, 402 needs Pro, 429 over the limit, 502 the upstream source is down.

Fair use

• Show where the data is from. On the free plan, link to coinbell.org near the data.
• Cache what you can. Most data changes every 1–10 minutes, so there is no need to ask every second.
• Don't resell the raw data or build a copy of this API from it.
• Keep keys secret. If one leaks, delete it and make a new one.
