Full site quality audit: 22 checks 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.

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.

Stay listed in this Bazaar: resources are delisted after ~30 days without a settled payment. $190 prepaid year, agent-payable (the card alternative is $19/mo at mudko.com/pricing): our funded wallet settles a small heartbeat to your endpoint twice a month - the USDC lands in YOUR payTo, so the heartbeat costs you nothing - we watch your merchant-feed entry weekly and alert + resurrect on any delisting. Requires an existing Bazaar Listing Package: pass the listing_key issued by https://mudko.com/api/x402/bazaar-listing.

Get YOUR x402 endpoint listed in this Bazaar - done for you, $99 one-time. You receive a deploy-ready x402 v2 kit generated for your stack (Next.js, Express, serverless; PHP via a free serverless function) with your wallet, price and discovery declaration baked in, plus a resumable listing_key that drives the automated pipeline via MCP (https://mudko.com/api/mcp): validate against Coinbase's own preflight with per-check fixes, and when your price is $1 or under WE fire the indexing settlement from our funded wallet. Ends with a receipt: settle tx + your live merchant-feed entry. Built by the team that listed its own endpoints first (this very listing is dogfood). Keepalive add-on available so you never fall out of the index.

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, competitors named instead, 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.

Buy the agent-readiness package for a website: we generate and deliver the full agent-callable surface (agent-card, MCP server-card, agent-skills, WebMCP bridge, OAuth discovery, robots.txt-for-AI, llms.txt, DNS-AID guide). Pay USDC on Base and receive a bundle_key that unlocks the deliverables immediately — no human, no card. Minimum $350; price is value-based per business.

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.
