Nownodes vs TWZRD Agent Intel
NOWNodes runs hosted full nodes for Bitcoin, Ethereum, and dozens of other chains, giving developers a single JSON-RPC/REST gateway instead of operating node infrastructure themselves. A free tier covers 100,000 requests for one month to get started, after which usage moves to metered Pro/Business/Enterprise plans billed per request volume. Every endpoint requires an api-key header.
TWZRD is a Solana-native trust layer that AI agents call before and after making an x402 micropayment, returning a signed reputation receipt for a given wallet instead of gating access behind a signup-based API key. A free sample receipt and verifier endpoint let integrators test the signing scheme before spending real USDC on a live trust lookup, priced at $0.05 per call. Its JSON responses carry no CORS headers, so it's built to be called server-side or by an agent, not from a browser.
