The Spawn is an on-chain AI agent catalog and discovery platform built around ERC-8004, a standard for registering agent identities and capabilities on blockchain networks. Its catalog indexes hundreds of thousands of agents across 30 chains, helping users browse agent endpoints, capabilities, activity checks, and quality signals. Visitors can explore listings by blockchain, review agent profiles, and find tools for tasks ranging from crypto trading and savings to account analysis and data access.

The platform also supports agent builders and businesses through spawnr MCP, which offers more than 30 tools for intelligence, extraction, scraping, swaps, verification, and payments. Its features include agent publishing, discovery and hiring resources, API documentation, setup guides, and support for agent monetization through x402 payment rails. The Spawn provides research tools for company, ecommerce, and people research, alongside due diligence and MCP tool discovery resources. Its educational materials explain topics such as ERC-8004, agent protocols, and registry use.
