此 MCP 可以做什么

Performs independent reasoning and adversarial verification of claims, including current web research and cited verdicts.

second_opinion_panel

Three independent adversarial verifiers attack the claim through different lenses (evidence, logic, currency) and vote ($0.75, ~90s). Use for high-stakes or contested claims where a single check is not enough. Without a payment argument it returns an exact pay-per-call quote (no account, no API key).

输入模式

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['claim'], 'properties': {'claim': {'type': 'string', 'maxLength': 2000, 'minLength': 8, 'description': 'The single claim to verify, stated plainly.'}, 'context': {'type': 'string', 'maxLength': 4000, 'description': 'Why this claim matters / where it came from.'}, 'payment': {'type': 'string', 'pattern': '^[A-Za-z0-9+/=_-]+$', 'maxLength': 20000, 'description': 'Base64 x402 payment payload built by YOUR wallet for one of the quoted accepts entries (the same string the X-PAYMENT header carries). Omit to receive a machine-readable quote.'}}}

second_opinion_pricing

FREE: current tiers, prices, and exact on-chain payment requirements (accepts) for every rail — Algorand, Base, Polygon, Solana. Use this to pre-build a payment, or to discover what a verification will cost before committing.

second_opinion_quick

Independent reasoning-only check of a claim ($0.02, ~20s, no web research). Use for logic, internal consistency, and stable established knowledge (definitions, architectures, history, maths). Returns refuted/supported/inconclusive with calibrated confidence; honestly escalates to second_opinion_verify when the claim needs current-world research. Without a payment argument it returns an exact pay-per-call quote (no account, no API key).

Omit to receive a machine-readable quote.'}}}

second_opinion_result

Fetch the verdict for a paid async job — polling is FREE and the verdict is already paid for. Returns status running|done|failed, with the full verdict when done.

输入模式

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['job_id'], 'properties': {'job_id': {'type': 'string', 'maxLength': 100, 'minLength': 4, 'description': 'The job id returned by a paid verification tool call.'}}}

second_opinion_try

FREE TRIAL — no wallet, no payment, no account: the same quick reasoning-only check as second_opinion_quick, 3/day per caller (claims up to 500 chars; global daily cap applies). The trial verdict is unsigned — paid verdicts add an offline-verifiable Ed25519 receipt and live web research on the verify/panel tiers. Try the product here; use the paid tools for real work.

second_opinion_verify

Independent adversarial verification with live web research ($0.20, ~60s). A separate AI attempts to refute the claim using current sources and returns a verdict with citations. Use before irreversible commitments that depend on current-world facts. Without a payment argument it returns an exact pay-per-call quote (no account, no API key).
