1 Best APIs for Archive Node Access in Nigeria

Chainstack is a production-grade blockchain infrastructure provider delivering managed RPC nodes, archive data access, real-time streaming, and dedicated node infrastructure across 70+ blockchain protocols. It is designed for teams building multi-chain applications, trading systems, analytics platforms, and AI agents that need reliable, high-performance blockchain connectivity without the overhead of running their own nodes. Chainstack serves developers ranging from solo builders on a free plan to enterprise trading desks on dedicated infrastructure. What the API Does Chainstack provides RPC (Remote Procedure Call) endpoints for reading and writing to supported blockchains including Ethereum, Solana, Bitcoin, Base, Arbitrum, Polygon, and 65+ more. Key capabilities include: full node RPC for current-state queries; archive node access for complete historical data; WebSocket subscriptions for real-time event listening; Yellowstone gRPC streaming for ultra-low-latency Solana data (blocks, transactions, account changes); advanced token and NFT APIs; and global routing that automatically directs requests to the nearest region. Pricing Tiers Developer (free): 3 million Request Units (RUs)/month, limited RPS, no credit card required. Growth: $49/month, 20M RUs, $15 per 1M overage RUs. Pro: $199/month, 80M RUs, $12.50 per 1M overage. Business: $349/month, 140M RUs. Enterprise: $990/month, 400M RUs, from $5 per 1M overage with custom SLAs. Chainstack uses RUs (1 RU for full node, 2 RU for archive) rather than per-method pricing — a cleaner billing model. Authentication API Key from Settings > API Keys in your Chainstack account. Keys are embedded in the RPC endpoint URL or passed as a header depending on the protocol. Rate Limits Vary by plan tier. Published per-plan RPS limits are available on chainstack.com/pricing.

Chainstack is a global infrastructure provider with no Nigeria-specific access blocks. Nigerian developers can sign up with an email and use the free tier immediately. Challenges and Gotchas (1) The RU model means archive queries cost 2x compared to full node queries — heavy analytics workloads burn RUs faster. (2) Free tier RPS is low — unsuitable for production traffic. (3) WebSocket connections count toward RU usage. (4) No fiat payment, wallet, or custody features — Chainstack is pure node infrastructure. (5) Solana gRPC streaming (Yellowstone) is a premium feature requiring appropriate tier. Company Background Chainstack was founded in Singapore and operates globally. It is backed by major venture capital and has grown into one of the leading multi-chain RPC infrastructure providers alongside Alchemy and QuickNode.
