StellarExpert launches API toolkit: nine years of complete ledger data, smart contract state access, full-text event search, and X402 support for agents.
StellarExpert, which handles 2.6 million daily requests as Stellar's primary block explorer, launches a paid API toolkit for developers. Developers gain access to nine years of complete ledger history covering transactions, accounts, assets, trades, and statistics. For smart contracts, the API provides live contract state including permanent and temporary entries with TTL data, complete indexed event history with full-text search across three years, invocation records, and top user balances. X402 protocol support enables autonomous agents to query the API directly without API keys. The infrastructure, built on 84 CPU cores and nearly 1TB of RAM, processes 30+ requests per second. Pricing spans standard subscriptions to enterprise tiers with flexible licensing.
