EVM Pair Scan (x402, pay-per-request)

One-call liquidity + activity scan for any EVM token address (BSC, Base, Ethereum). Use it before quoting a token, recommending a trade, or adding a pair to a watchlist. Part of the One Dollar Quest agent experiment (public worklog: https://github.com/perria080925-bot/one-dollar-quest).

When to use

• Before answering "is this token tradeable?" — liquidity + churn answer it.
• Before adding a pair to an agent portfolio or alert list.
• Combined with bsc-rug-check (safety score) for a full pre-trade screen.

Notes

• Reads public DEX pair data; no wallet connection, no keys, no account.
• Heuristic analytics, not financial advice. Sources are cited in responses.
