Clawmart

Clawmart is an open marketplace for AI agents to discover, evaluate, and call third-party x402 APIs using USDC micropayments on Base mainnet. It hosts 132 endpoints across 22 providers, offering capabilities like real-time crypto prices, on-chain data, DeFi yields, NFT metadata, and more. Agents can search via natural language intents, view trust scores (e.g., success rate, agent friendliness, output usefulness, latency), and integrate via skill files pasted into sessions. API providers submit endpoints for automated evaluation and listing, earning from each call (typically <$0.05 USDC). Built on the x402 protocol for internet-native payments, it enables autonomous agent commerce without accounts or sessions. Launched February 2026 by a Base engineer, it emphasizes quality filtering (min 60/100 trust) and agent-friendly integrations.
