Overview: A production-grade Blockchain API for Python that simplifies Web3 development. Connect to popular chains, fetch on-chain data, interact with smart contracts, and manage wallets using a clean, well-documented Python SDK. Key Features: - Multi-chain coverage: Ethereum, Polygon, BNB Chain, Arbitrum, Optimism, Avalanche, and more. - Data access: blocks, transactions, logs, ERC-20/721/1155 balances, token metadata, prices, and NFT ownership. - Smart contracts: ABI-based calls, transaction building, event subscriptions, and gas estimation. - Real-time streams: WebSocket endpoints for mempool, confirmations, and contract events. - Wallet tools: address generation, balance checks, nonce management, and client-side signing. - Developer experience: typed models, retries, backoff, pagination, timeouts, and rich errors. - Security-first: HTTPS/TLS, key-based authentication, environment variable support. - Performance: high-throughput endpoints, caching hints, and efficient batching. Use Cases: - dApps and wallets with reliable chain connectivity. - Trading and arbitrage bots with low-latency streams. - Analytics dashboards and compliance monitoring. - Payment rails and invoice reconciliation on-chain. - NFT marketplaces, indexers, and portfolio trackers. Compatibility: - Python 3.8+. - Works with popular frameworks (FastAPI, Django, Flask) and async event loops. - Integrates with web3.py and standard cryptographic libraries. What’s Included: - Python package (SDK) with REST and WebSocket clients. - Detailed documentation and quick-start guides. - Sample notebooks, code snippets, and test fixtures. - Support channels and versioned changelogs. Getting Started: 1) Install: pip install blockchain-api-python 2) Configure: set API_KEY as an environment variable 3) Connect: initialize the client and call endpoints 4) Deploy: scale confidently with production-ready features and best practices. Support & SLA: - Email and ticket-based support. - Regular updates and security patches. - Uptime-focused infrastructure. Note: Private keys remain client-side.
