Offers

Offer	Endpoint	Price
X402 Audit Full site quality audit across SEO (titles, descriptions, canonical, Open Graph, JSON-LD…), accessibility (alt text, form labels, heading order, landmarks…) and security headers (HSTS, CSP, XCTO…) — scored 0-100 per section with a copy-paste fix for every finding. $5 per audit. Fetch-based (served HTML; SPA shells noted). The agent-readiness scan is separate and free at /api/x402/deep-scan.	`/m/bz-mudko-com/api/x402/audit`	5 USDC
X402 Batch Scan Bulk agent-readiness screening for agencies, VCs and portfolio owners: scan up to 50 URLs in one paid call ($0.02/URL, $0.10 minimum) and get a compact per-URL verdict — level 0-5, passing checks, top gaps. The single-URL scan with full evidence stays free at /api/x402/deep-scan; this buys scale and rate-limit bypass.	`/m/bz-mudko-com/api/x402/batch-scan`	0.1 USDC
X402 Citation Check Live AI-citation check: runs fresh probes against major AI assistants and reports whether a domain is cited for its vertical's buying questions — citation rate per provider, list position, and whether the domain's agent-card was discovered. Fresh probes per call (not cached). $0.50 per check. Free companion diagnosis: /api/x402/deep-scan.	`/m/bz-mudko-com/api/x402/citation-check`	0.5 USDC
X402 Verify Counterparty Counterparty trust verification for agents: before transacting with a domain, verify its trust artifacts — DNSSEC + DNS-AID records, agent-card, live MCP endpoint, published JWKS, OASF record, x402/commerce declarations. Returns a 0-100 trust score with per-artifact evidence. $0.25 per lookup.	`/m/bz-mudko-com/api/x402/verify-counterparty`	0.25 USDC

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-mudko-com/api/x402/audit')
// 402 challenge signed and settled automatically; response includes Payment-Receipt
