Wodan Posture

Paid: $0.01 USDC on Base per call, paid automatically by an x402-capable MCP client. No signup, no API key. Analyses one public http(s) URL and reports whether an agent may treat it as a machine-readable data source: exact-path robots.txt verdict, bot-wall vendor, JavaScript requirement, extractable content, JSON-LD types, licence hint, evidence lines. Verdicts: open, machine_readable, robots_disallowed, bot_walled, auth_required, js_rendered, thin_content, unreachable. An unanalysable URL is never charged for (error target_not_analysable). Argument: url. Free alternative for the verdict alone: posture_preview.

Paid: $0.02 USDC on Base per call, paid automatically by an x402-capable MCP client. No signup, no API key. For one public http(s) URL returns the posture verdict plus where the data is: sitemaps (robots.txt Sitemap lines and /sitemap.xml, with the status observed), RSS/Atom feeds, whether /llms.txt answers 200, the status of /.well-known/x402, ai-plugin.json and mcp.json, JSON/CSV/XML endpoints, JSON-LD types, licence hint. Every field is observed or explicitly empty with a reason. An unanalysable URL (target_not_analysable) or a site that advertises nothing (nothing_to_report) is never charged for. Argument: url.

Paid: $0.03 USDC on Base per call. No signup, no API key. Returns the machine-readable data one public http(s) URL already publishes: every JSON-LD block, OpenGraph/Twitter-card/standard meta, embedded JSON state blobs (e.g. __NEXT_DATA__), parsed entries if the document is RSS/Atom/JSON Feed, HTML tables, and alternate/canonical links - each capped and returned exactly as observed, nothing invented or inferred by a model. Does not render JavaScript, does not follow links off the page, does not summarize. An unanalysable URL is never charged for (error target_not_analysable); a page with nothing extractable answers nothing_to_report, also uncharged.

Paid: $0.05 USDC on Base per call, as GET /v1/pages/posture?url=...&url=... (repeat url up to ten times) or POST /v1/pages/posture with a JSON body. No signup, no API key. Analyses up to 10 public http(s) URLs in ONE payment and ONE settlement, instead of paying page_posture ten times: the same access-posture report as page_posture, per URL, as a verdict array. An individual unanalysable or empty URL is never a batch failure - it is reported as its own error entry in results, target_not_analysable or nothing_to_report - and the batch is only charged (settles) when at least one URL could be analysed; if every URL fails the whole call answers 404 and nothing settles. Free companions cover a single URL: posture_preview and robots_check.

      "description": "1 to 10 public http(s) URLs to analyse in one payment. Each is analysed independently: an unreachable or private URL never fails the batch, it is reported as its own error entry in results. Private, loopback and link-local addresses are refused per URL.",

Free, no payment and no signup: 60 calls per hour, shared across all callers. Returns the headline of the same analysis - verdict, confidence, the full report's field schema, one evidence line and the price - so a caller can decide before paying. Use it when you only need the verdict; call page_posture ($0.01) for the complete report with evidence and provenance.

Free, no signup: shares posture_preview's 60-calls-per-hour budget across all callers. Answers the RFC 9309 question for one public http(s) URL and one crawler token (argument agent, e.g. 'GPTBot'; optional, defaults to the wildcard '*' group): may this agent fetch this URL? Also reports the same decision for '*', gptbot, claudebot, googlebot, perplexitybot and ccbot in one call. An unreachable or unparsable robots.txt is reported as status unknown with allowed null - never guessed as allowed. The HTTP equivalent is GET /v1/robots/check. For the wider questions this tool does not answer: page_posture ($0.01) is the full access-posture report, page_sources ($0.02) is where the data is, page_data ($0.03) is the data itself.
