Every convention below is what that card states, plus what the edge returned to live probes. Where the card is silent the value is an honest undocumented/none, not a guess. The host answers a Cloudflare managed challenge to every application request from a non-browser client, so nothing here was confirmed against a real response. auth: style: x402 payment (HTTP 402 -> pay USDC on Base -> retry with receipt) on paid endpoints; none on calibration/reputation reads detail: authentication/verse-me-com-authentication.yml idempotency: supported: false coverage: none mechanism: null header: null scope: [] retention: undocumented description: >- No idempotency key, request id or replay-protection mechanism is documented for the paid POSTs (/expertise/consultation, /expertise/edgar, /expertise/epistemic-audit). The x402 payment receipt is bound to one payment, which prevents the same payment being spent twice, but nothing states whether resubmitting the same question with a new payment is deduplicated. Coverage none. dry_run_mode: supported: true grade: documented operation: POST /expertise/consultation/price-estimate description: >- A free price preview exists before any payment: the card lists "Price estimate — POST /expertise/consultation/price-estimate — Preview cost before paying" among its freeEndpoints, and the consultation skill says "Use POST /expertise/consultation/price-estimate for a preview." It rehearses the cost, not the answer. Not observed live (edge challenge). reversibility: grade: none write_surfaces: - surface: POST /expertise/consultation (x402 payment $3–$50 USDC) reversal: undocumented window: undocumented - surface: POST /expertise/epistemic-audit (x402 payment) reversal: undocumented window: undocumented - surface: POST /expertise/edgar (x402 payment $0.01–$0.25 USDC) reversal: undocumented window: undocumented description: >- Every write is a purchase settled on-chain in USDC, and the card states no refund, cancel or dispute path and no window. On-chain settlement is final by construction unless the provider publishes a refund mechanism, and none is published. Graded none rather than na because a paid write surface exists. The only mitigation the provider offers is the free price-estimate dry run before paying. pagination: style: undocumented description: The calibration history endpoint returns "cumulative daily snapshots"; no page/cursor/limit parameter is documented. versioning: scheme: undocumented current: agent card version 2.0.0; supportedInterfaces protocolVersion "1.0"; x402 version 1.0 description: No URL versioning, changelog or deprecation policy is published.
