Pre Trade Check Call
Pre-trade risk check for AI agents trading crypto: live orderbook slippage at YOUR size, side-aware funding carry, open-interest crowding, and optional contract security — composed into a single ok/caution/avoid verdict with per-factor reasons and raw data embedded. Answers 'is this trade sane?' before trading, not after. Replaces four API integrations plus the judgment layer.

Verified Route Call
Buyer-side trust oracle for the x402 marketplace: 'I need X, budget $Y — which tool is real?' Sweeps the WHOLE catalog across many queries, collapses sybil/factory clusters (one wallet stamping many fake-distinct listings), ranks the genuinely-used survivors by unique-payer usage, and returns one vetted pick with a ready-to-pay challenge. The credit-bureau check an agent can't do in a single query

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-agentpay-tools/tools/pre_trade_check/call')
// 402 challenge signed and settled automatically; response includes Payment-Receipt

Or inspect the challenge yourself:
