  "description": "Paid tools for AI agents, x402 micropayments per call: Bierus Site Audit API: Evidence-based website audit: quick audit-live (~2 min) or full Bierus v2 audit with PDF (10-15 min), pay on delivery. Deploy Proof: Signed delivery proof for coding agents: passive website, SEO, security and checkout checks. Trust Check: Should my agent pay this provider? x402 offer, payee, uptime, ERC-8004 identity. Vendor Due Diligence Report: Readable seller report: reputation, sanctions, recalls, EU-Ready, email auth; signed evidence. Address Geocode: US street address (Census) or UK postcode (ONS) to coordinates and official areas. No match = not charged. Agent Check: verify a peer agent before you call or pay it (A2A card, MCP server health, x402 offer). Indicative score, not a certification. Agent-ready score 0-100: AI-bot access, llms.txt, A2A, MCP, x402 discovery, OpenAPI, with fixes. Clone Blueprint: architecture plan + install checklist for an AI sales-agent agency, an AI B2B trading house or an API store for AI agents (49 USDC, no source code). Email Check: is this address deliverable (syntax, MX, disposable, role) and how healthy is the domain's email authentication (SPF, DMARC, DKIM, MTA-STS, BIMI). DNS + RDAP only, no email sent, addresses not stored. Escrow Evaluator: indicative rule-based pass/partial/fail verdict on an agent deliverable with a signed EIP-712 attestation (ERC-8183 reason). Holds no funds, sends no transaction; evaluator address 0xD999A24d377086a2Fa887491f2986033Bfc3E26C. EU-Ready Pre-Purchase: EU Safety Gate alerts, GPSR responsible person on the page, seller sanctions and ECB price in one call, with a ready/review/block decision. Fragrance Authenticity Check: counterfeit-risk signals for a perfume listing (channel, price per ml, fake words, seller trust, Safety Gate, batch code). FX Rates: official ECB reference rates since 1999 plus 9 official pegs (CFA francs, KMF, CVE, AED, SAR, QAR, BHD, OMR) \u2014 39 currencies; convert, series, latest. Information rates, not transaction rates. Pre-Purchase Check: price/stock + seller trust + product recalls in one call, with an advisory proceed/caution/stop decision. Price Availability: verified price, currency and stock from a product page's structured data (robots.txt respected; blocked pages not charged). Recall Check: is this product recalled? US CPSC + FDA and France RappelConso, by keyword or barcode. Decision aid, not an official verification. Sanctions Screen: one name against OFAC, UN, EU and UK sanctions lists (refreshed every 6 h) plus OFAC crypto addresses. Screening signal for human review, not legal or regulatory advice; names are not stored. Seller Reputation: indicative 0-100 trust score for an online store before paying (domain age, TLS, email auth, policies, phishing lists). Signal, not a guarantee. SEO Audit Shop: live technical SEO, keywords & content, internal links (crawl), local presence (NAP, LocalBusiness, Maps/reviews) and AI-answer visibility (GEO) for any public URL; full audit with weighted score and priority fixes. Rule-based, robots.txt respected. Trust Trio: A2A card + MCP server + x402 offer checks of an AI agent in one call. USDC Receipt Verify: proof that a USDC payment on Base matches recipient, amount and confirmations. Read-only; unknown tx = not charged. Vendor due diligence: seller reputation, sanctions, product recalls and EU-Ready in one call. Bounded deterministic checks on supplied JSON; no external verification. Invoke each skill through its x402 HTTP endpoint (see skill examples and /catalog) or through the MCP hub (Streamable HTTP, JSON-RPC). No account or API key: pay per call in USDC. LIVE: real USDC on Base mainnet (eip155:8453), settled on-chain via the Coinbase CDP x402 facilitator. Errors and invalid requests are never charged.",
