Covalent vs TWZRD Agent Intel
Covalent's blockchain-data platform rebranded to GoldRush, unifying wallet balances, transaction history, NFT ownership, and token/DEX pricing across 100+ EVM and non-EVM chains behind one API, plus JSON-RPC endpoints for 30+ EVM networks. New accounts get a 14-day trial (25,000 credits) before moving to a paid plan or per-request (x402) billing with no monthly minimum. All data comes back as JSON.
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.
