Blockchain

Overview

Blockchain.com’s APIs serve Bitcoin data — prices, blocks, and charts. The public price endpoints work without auth (verified live); some endpoints need a key.

Quick Start

Price ticker — keyless (verified live):

curl "https://blockchain.info/ticker"

{
  "ARS": { "15m": 1151860620.4, "last": 1151860620.4, "buy": 1151860620.4, "sell": 1151860620.4, "symbol": "$" },
  "USD": { "15m": 68000.0, "last": 68000.0, "buy": 68001.2, "sell": 67998.9, "symbol": "$" }
}

Block info / stats:

curl "https://blockchain.info/rawblock/0000000000000000000000000000000000000000000000000000000000000000"
curl "https://api.blockchain.info/stats"

• Higher-tier endpoints (exchange rates, websocket) may need a key.

Rate Limits & Notes
