# Ordiscan

> Bitcoin blockchain explorer for Ordinals, Runes, BRC-20, Alkanes, and Rare Sats.

Ordiscan indexes and displays Bitcoin metaprotocol data. It provides a public REST API for querying addresses, transactions, inscriptions, runes, BRC-20 tokens, alkanes, rare sats, collections, and blocks.

## API

Base URL: `https://api.ordiscan.com/v1/`

Authentication: Pass your API key as a Bearer token in the `Authorization` header.

The API also supports the x402 payment protocol (V2) for pay-per-request access without an API key. Requests without authentication receive a `402 Payment Required` response with a `Payment-Required` header containing payment instructions. Clients can pay with USDC on Base using tools like `awal` (Coinbase Agentic Wallet) or `@x402/fetch`, which handle the payment flow automatically.
