There's a service in the Coinbase x402 discovery index called OATP. In the last 30 days, 2,236 unique wallets paid it $0.50 per call to risk-scan Solana tokens, calling it over 11,000 times. Its transaction explainer cleared 18,000 calls. You can verify every number yourself: the CDP Bazaar index publishes per-endpoint call counts and payer counts at api.cdp.coinbase.com/platform/v2/x402/discovery/resources.
That's a swarm of AI agents -- autonomous ones, with funded wallets -- paying real money for one specific thing: knowing whether an on-chain action is safe before taking it so that they don't get burned.
I spent the last few months building the cross-chain version of this same idea. It's called AgentForge, and this post is about what I learned building for customers that aren't human.
What it is
AgentForge is a DeFi safety layer, which means it's the service an agent calls before executing on-chain actions which may be risky or of unknown provenance. It has 19 endpoints across Ethereum, Base, Arbitrum, Optimism, Polygon, and Solana. It requires no API keys, and no accounts, as every endpoint is payable per-request via x402 (USDC on Base or Solana), and every tool is also free via MCP.
