Free on testnet. Automated scan, not human-verified. Scan-only quick read of whether AI agents can discover and buy from a website. Returns the engine's report as-is: scanner_version and scan_id ("v4"), report.score (scan-only), report.band (can be 'Partly assessed'), report.coverage, report.summary, report.confidence, report.can_agents_buy, report.who_eats_the_loss (display label "Who carries the risk?"; needs the 5 answers, so not assessed here), report.archetype ('unclassified' if not classified), report.rows (with unknown_reason), report.gaps, report.actions (always exactly 3: 2 business then 1 technical, each with kind "business" | "technical"), report.ledger (related Ledger entries), checks, evidence, findings, and scan_interrupted.reason (timeout|blocked|dns_tls|robots_disallowed|refused|http_error) when the scan could not finish. Input: a bare domain (e.g. "yourstore.com"). It reads public pages only; it is NOT a certification, audit or legal advice. Open questions only the business can answer come back with a link to https://thepaymentsnotes.com/readiness. Limits: 3 scans per caller per day and 50 per day overall, shared with the website; results are cached for 24h. Weekly newsletter: https://thepaymentstack.substack.com
DiscoveredFree on testnet. Status of one Ledger row (protocol, platform, wallet or stablecoin) from the human-verified Ledger: headline, status, last verified date and ONE source URL. If the name is not in the Ledger: result="unknown" plus up to 3 did_you_mean names (never a guessed answer). Call list_protocols to see every name.
DiscoveredFree on testnet (no payment, no wallet needed). Fuller answer for ONE Ledger row (protocol, platform, wallet or stablecoin): headline, status (authoritative), maturity (a plain-English stage derived from status, never contradicts it), steward, what_this_means (the detail after the headline, omitted if there is none), latest update date, verified date and up to 3 sources. Unknown names return result="unknown" with up to 3 did_you_mean names. Call list_protocols to see every name.
DiscoveredFree on testnet. Every row in the human-verified Ledger (protocols, platforms, wallets, stablecoins): name, short names/aliases and status only. Use a name from here with get_status or get_status_detail.
DiscoveredFree on testnet. Free-text keyword search over the human-verified Ledger (protocols, platforms, wallets, stablecoins). Returns up to 5 matching row NAMES with status, a relevance score and which fields matched (exact_name, name, steward, status, text). It returns names, not answers: call get_status or get_status_detail with a returned name for the verified headline, date and source. No match returns result="none" (never a guess). Example: {"query":"pay per API request for a data feed","limit":3} -> {"result":"found","hits":[{"name":"x402","status":"Live (Limited)","score":9.1,"matched":["text"]}, ...]}.
DiscoveredFree on testnet. Recent verified Ledger changes since a date (last 30 days, max 5 items): headline, status, date, one source.
