TWZRD Agent Intel vs Watchdata
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.
WatchData operates hosted JSON-RPC nodes across Ethereum, Polygon, BNB Smart Chain, and other networks, plus higher-level "Powered API" endpoints for token balances, transfer history, and block-timestamp lookups that would otherwise require custom indexing. Every call needs an api_key issued from the dashboard after a free signup, with a 100-million-unit free monthly allowance before paid plans apply. Responses are plain JSON-RPC.
