Tools as reported by the server

• get_protocol_info
  Returns the SAAX Protocol version, available capability count, and the URL to the specification. Call this when an agent needs a one-time overview of the protocol. For pricing, use get_routing_fee. For the full capability list, use list_capabilities. For a liveness check, use ping.
• get_routing_fee
  Returns the current routing fee schedule. Call this before initiating a routing request to determine the expected cost. For capability discovery, use list_capabilities. For protocol overview, use get_protocol_info.
• ping
  Returns a lightweight liveness response. Call this to verify the endpoint is reachable. Do not use for discovery, capability listing, or pricing — use get_protocol_info, list_capabilities, or get_routing_fee instead.
• route_request
  Submits a capability request and returns ranked supplier matches. Commitment creation with payment runs through the HTTP POST /route endpoint, not this tool. Use list_capabilities first to discover available capabilities. For commitment lookup after routing, use get_commitment.
• get_commitment
  Returns the full commitment object for a given commitment ID — including terms, state, manifest hash, and evidence references. Call this when an agent needs the complete commitment record. For status-only polling, use get_commitment_status. For listing all commitments for a subscriber, use list_comm
• list_capabilities
  Returns the capabilities currently indexed by the SAAX Router, with supplier counts per capability. Call this to discover what can be routed. For pricing of a specific capability, use get_routing_fee. For protocol overview, use get_protocol_info.
• list_commitments
  Returns all commitments associated with a subscription email. Requires an active SAAX Premium subscription. Call this to retrieve commitment history for a subscriber. For a single commitment by ID, use get_commitment. For status-only checks, use get_commitment_status.
• get_commitment_status
  Returns only the current lifecycle state for a given commitment ID, plus the recommended next action for the calling agent. Call this before retrying any commitment that timed out — an unknown outcome is a status check, not another POST. The next_action field tells the agent whether to retry, poll,
• create_commitment
  Creates a governed commitment between a buyer and a seller and persists it to the SAAX commitment store. The commitment is settlement-rail-neutral: settlementRail is metadata only (x402, mpp, ap2, acp, or unspecified) and is NEVER a prerequisite. Returns the new commitment id (saax_<hash>), createdA
• get_evidence_verification
  Verifies external evidence against a commitment's acceptance criteria. Requires an active SAAX Premium subscription. For authority proof validation, use get_authority_validation.
• get_authority_validation
  Validates an authority proof against a commitment. Requires an active SAAX Premium subscription. For evidence verification, use get_evidence_verification.
