Verify Toolagenttoolindex.xyz
Verifies any ERC-8257 tool. Given a chain_id and tool_id, it reads the tool's onchain registry config, confirms the manifest hash matches the hosted manifest, probes whether the tool's endpoint is live, decodes access predicate and x402 payment requirements, and returns a trust report with a callable verdict. A public-good verification primitive for agents vetting tools before they call them.

BASE167 claim check
BASE167 claim checkbase167.com
Check whether a wallet qualifies for the BASE167 airdrop on Base mainnet and get the transaction to claim it. A wallet qualifies with 167 or more Base transactions.

Every wallet type works, including ERC-4337 smart accounts, Base Account, Safe and 7702-delegated EOAs. The wider surface -- the monthly Degen Games trading competition, its boards and its enrolment endpoints -- is documented at https://base167.com/llms.txt and https://base167.com/openapi.json, with an MCP server at https://base167.com/mcp.
