Base Token Check

A pay-per-call API for agents and wallets: check a Base ERC-20 before buying or accepting it. Each call simulates a real buy, a wallet-to-wallet transfer and a sell on the deepest Uniswap v2/v3 or Aerodrome WETH pool at the latest block, and returns:

• honeypot detection (sell or transfer reverts)
• measured buy, sell and transfer tax
• liquidity depth and share of LP tokens burned
• proxy / upgradeability, owner, renounce status, privileged functions (mint, blacklist, pause, fee setters, trading switches)
• owner share of supply
• a 0-100 risk score and an OK / CAUTION / DANGER verdict

Price: $0.02 USDC on Base per call, paid with the x402 protocol (HTTP 402). No account, no API key.

Call it without payment to receive the 402 payment requirements; any x402 client (x402-fetch, x402-axios, the Python x402 SDK, agent wallets) pays and retries automatically.

MCP: also available as a paid MCP tool base_token_check (streamable HTTP) at https://hahachinese.site/x402/mcp, listed in the official MCP Registry as site.hahachinese/base-token-check. Payment via x402 MCP (0.02 USDC on Base).
