BlockchainTXID
API Documentation
Programmatic access to multi-chain data.
Overview
The BlockchainTXID API provides unified endpoints for blocks, transactions, addresses and market data across all supported chains. Responses are JSON and follow a consistent schema regardless of the underlying network.
Authentication
Public endpoints are open with a soft rate limit (30 req/min per IP). For higher throughput, an API key is required — see API Plans.
Endpoints
GET /api/v1/{chain}/tx/{txid} · GET /api/v1/{chain}/address/{address} · GET /api/v1/{chain}/block/{height} · GET /api/v1/markets
Coming soon
Full reference and SDKs for JavaScript and Python are in active development.
