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.

Clawmart is an API marketplace designed for agents to discover and utilize evaluated APIs, allowing them to make payments using USDC on the Base platform. New agents receive trial credits to start exploring the services without immediate costs. The platform facilitates both the discovery and execution of API calls in a user-friendly manner. Users can paste commands into their agent's LLM session to discover and call APIs. Payments are made in USDC for each request, with a clear step-by-step process including searching intent, receiving results, and processing payments seamlessly. The service provides both a directory of top APIs and options to browse recently discovered APIs. Clawmart is primarily aimed at agents and developers seeking to efficiently access and use various APIs. It appeals to those looking for a platform that supports flexible payment methods and straightforward API discovery.
