Quick Bierus website audit (audit-live engine, 6 steps): reads the site, asks AI assistants (Google AI Mode/Overview, ChatGPT, an LLM), checks online reputation, Lighthouse mobile speed and security headers, then writes findings with evidence and a PDF report (EN/FR). Async: job_id + free result_url

Full Bierus v2 website audit: ~40 stable control ids (ok / ko / not measured / not applicable) with dated sources: reputation, checkout path (stops at the payment page), reviews and claims, AI visibility, DNS/e-mail auth, JS key leaks, passive security, Lighthouse mobile; guarded French PDF report (

Signed passive website proof: page reachable, TLS certificate, http→https, response time, title, mixed content, real 404, internal links sample, optional expected text. ok/ko/not_measured + EIP-712 attestation.

Signed passive SEO proof: SEO module scores (technical, content, links, local, AI visibility), title/meta lengths, canonical, single h1, lang, JSON-LD, indexable, sitemap. ok/ko/not_measured + EIP-712 attestation.

Signed PASSIVE security basics: TLS 1.2+, certificate expiry, HSTS, CSP, framing, nosniff, referrer policy, version disclosure, cookie flags, known-vulnerable JS versions in script URLs, mixed content, SPF/DMARC, security.txt. No scanning.

Signed passive checkout-path proof for a store or product page: price/currency/availability, add-to-cart control, cart page, checkout links over https, payment provider, terms/returns/privacy/legal pages reachable, contact. Nothing added to cart, no payment.

Full signed delivery verification: website + SEO + security basics (+ checkout if store=true) + the client's acceptance criteria (expected texts, pages that must answer). One verdict pass/partial/fail and one EIP-712 attestation over all measurements. Async: job_id + free result_url.

Trust decision (trust/caution/avoid + score) for one paid agent provider: x402 offer, MCP, A2A card, 3 unpaid availability probes, domain reputation, OFAC check of payTo, ERC-8004 identity and agentWallet = payTo on Base.

Compare 2-5 paid agent providers with the same measured checks and rank them (decision, budget, trust score, price, latency); returns the recommended provider and why.

Readable vendor due-diligence report: reputation, sanctions (OFAC/UN/EU/UK), product recalls, EU-Ready, email authentication, product offer; proceed/review/block, Markdown report, signed evidence hash. Async if slow (job_id + free result_url), cached 24 h.

Geocode one US street address with the U.S. Census Bureau: standardised address, lat/lon, state, county, census tract, block group, ZCTA, metro area, congressional district (official GEOIDs). No match = not charged.

UK postcode lookup (ONS Postcode Directory via postcodes.io): lat/lon, country, region, local authority, ward, parliamentary constituency, NHS ICB, police force, LSOA. Unknown postcode = not charged.

Fetch and validate a peer agent's A2A Agent Card (v1.0 / v0.3): fields, skills, interfaces, auth, signature, reachability. Score 0-100 + issues.

Real MCP Streamable HTTP handshake (initialize + tools/list, no tool call): reachability, protocol version, tools, schemas, latency, OAuth metadata.

Pre-payment check of an x402 endpoint: one unpaid request, decodes the 402 offer (v1/v2): network, USDC or not, USD price, payTo, testnet, red flags.

Diagnose another agent's discoverability: robots.txt rules against the main AI crawlers, llms.txt, A2A agent card and its mandatory fields, MCP manifest, OpenAPI with x402 payment metadata (structured price, protocols, declared 402), and optionally a live 402 challenge on a given endpoint. Returns a

Repair kit for another agent: diagnoses it, then returns ready-to-paste files — a complete llms.txt, a valid A2A agent card, the exact x-payment-info block and 402 response declaration that directories require, and the robots.txt rules to unblock GPTBot, ClaudeBot, PerplexityBot and the others. Buil

Upgrade plan for another agent: the same diagnosis turned into an ordered, prioritised work list, each item stating the concrete effect on discovery or conversion (why a missing /openapi.json means noDiscovery, why a 400 instead of a 402 loses the endpoint in a directory probe, why a time pass beats

Subscribe one agent to monitoring for 24 hours: an immediate first measurement plus one deterministic re-check, with history and regression alerts. Returns a sub_id and a token; read your state for free at /agents/monitor/status. Use it to test the service on one agent before committing to a longer

Subscribe one agent to monitoring for seven days: an immediate first measurement then one re-check per day, with full history and regression alerts (score drop, a document that disappeared, a broken 402 challenge, new OpenAPI defects). Built for the same agents that poll us: it is cheaper and more u

Subscribe one agent to monitoring for thirty days: thirty daily deterministic re-checks with history and regression alerts. The cheapest per-check horizon; for an operator running several agents or an index that must stay discoverable.

Agent-ready score 0-100 (A-F) of a website or API: AI-bot access, llms.txt, A2A agent card, MCP manifest, x402 discovery, OpenAPI and agentic-commerce markup, with fixes ranked by impact.

The worst discoverability failures currently measured across real x402 origins: score, verdict, missing documents (llms.txt, A2A card, MCP manifest, openapi.json), blocked AI bots, OpenAPI defects, and the concrete ordered fixes. For an operator or directory that wants to know who to help, partner w

The full repair map: every scanned origin with its score, missing documents, blocked bots, openapi defects and fixes, plus a histogram of the most common failures across the market. Sell it to aggregators, directory operators and anyone building on x402 who needs to know the health of the ecosystem.

Measure one agent and receive a signed, transportable attestation of its discoverability. Publish it on your site or give it to a directory: anyone can verify it offline via POST /agents/certify/verify (free). This is the difference between saying 'my agent is agent-ready' and proving it, dated and

Architecture plan + installation checklist for one AI-run business: clone=agency (AI sales-agent agency), trading-house (AI B2B trading house) or api-store (API store for AI agents). Components, data flows, build phases, done-when checklist, go-live checks. No source code, no revenue promise. Unknow

Validate one email address without sending mail: syntax, MX, disposable, free webmail, role account, SPF/DMARC. Returns deliverable/risky/undeliverable/invalid with score.

Audit a domain's email authentication: MX, SPF, DMARC, DKIM (20 selectors), MTA-STS, TLS-RPT, BIMI and domain age. Returns an A-F grade with concrete fixes.

Evaluate a deliverable (text, JSON or URL) against a job spec (free text or JSON criteria): verdict pass/partial/fail, score, checked criteria, and a signed EIP-712 attestation whose digest is the ERC-8183 complete/reject reason. No funds held.

Verify an attestation token issued by evaluate_deliverable: recovers the EIP-712 signer, checks it is our evaluator, returns verdict, score, jobId and the bytes32 reason.

Before buying or selling a product in the EU: Safety Gate alerts (barcode or brand+words), GPSR manufacturer / EU responsible person on the page, seller sanctions (OFAC/UN/EU/UK) and price at the ECB rate, with a ready/review/block decision.

Risk signals for a fragrance listing: sales channel, price per ml, listing words, seller domain and EU Safety Gate. Does not authenticate a physical bottle. Provide url, or brand and seller_domain.
