Countersignatory

The going rate for a human minute.

Countersignatory publishes the going rate for a human minute: a live spot index for verified human judgment, and a quote engine that prices a task before you commit to it. Four markets, ranked by what the responder has at stake: Check (one screened human, a quality score at stake), Consensus (several humans who must agree), Countersign (a named, register-verified professional who signs the record), and Seal (a regulated act such as remote notarisation). Quotes return an indicative price, a band, urgency and off-hours multipliers, alternatives that would clear a lower bid, and the implied rate per human minute. A published wage floor of $0.25 net per active minute is in force, responders are never charged, and every seeded number's derivation is public. The quote engine and index are live; the market itself opens after the current demand-measurement window. Keys are free, instant and unapproved.

MCP server

  • Endpoint: https://countersignatory.com/mcp
  • Transport: Streamable HTTP, stateless, no sessions
  • Auth: none required. An optional bearer key, free and instant from POST https://countersignatory.com/v1/keys, is recommended so a caller counts as one caller.

Tools

Three tools are served. The descriptions below are exactly what the endpoint returns from tools/list.

countersignatory_quote

Get the current spot price to have a verified human check, agree on, sign off or notarise something. Use when an agent needs human judgment, accountability or a signature, and needs to know the cost and time before committing. Returns an indicative price, a band, what would clear at a lower bid, and the implied rate per human minute.

Parameters: task_type, sla_seconds, tier, consensus_n, unassisted, jurisdiction, max_price.

countersignatory_register_interest

Record that the quoted price would clear your use case and you would buy at it. Takes the quote_id from a countersignatory_quote response. This is the demand signal that decides which markets open first.

Parameters: quote_id, would_pay, note.

countersignatory_spot_index

The public Countersignatory Spot Index: the going rate for verified human judgment by market, with the urgency and off-hours multipliers, the published wage floor, and the derivation of every seeded number.
