Factual momentum + order-flow signal for a Base token: price trend (5m-24h), buy/sell pressure, and volume trend, classified as RISING/FALLING/FLAT + ACCUMULATION/DISTRIBUTION and gated by a live honeypot check. For trading agents — the read, not a prediction.

V1 Token Risk
Rug/tradeability risk VERDICT for a Base token: a 0-100 score and SAFE/CAUTION/AVOID call from liquidity depth, 24h volume, DEX diversity, pool age, ERC-20 validity, holder concentration, and a live honeypot/sell-tax simulation. Judgment for trading agents, not raw data.

Pay with an agent

Any MPP or x402-compatible client works. With mppx, payment is automatic:

import { Mppx, evm } from 'mppx/client'
import { privateKeyToAccount } from 'viem/accounts'

const mppx = Mppx.create({
  methods: [evm({
    account: privateKeyToAccount(process.env.KEY),
    currencies: [evm.assets.base.USDC],
  })],
})

const res = await mppx.fetch('https://api.meshgateway.co/m/bz-gate402-app/v1/best-swap')
// 402 challenge signed and settled automatically; response includes Payment-Receipt

Or inspect the challenge yourself:
