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>), createdAt, status, and the settlementRail. Call this BEFORE any payment flow to establish the governed commitment record. Once created, use get_commitment to read the manifest.
The commercial terms: deliverable, price, deadline
The buyer's identity: 0x-address or agent id
The seller's identity: 0x-address or agent id
Objective acceptance criteria for fulfillment
Recovery policy on failure
The settlement rail as metadata. Never a prerequisite; 'unspecified' is valid.

}Validates an authority proof against a commitment. Requires an active SAAX Premium subscription. For evidence verification, use get_evidence_verification.
| Argument | Type | Description |

| proof* | any | The AuthorityProof object (proofType, issuer, subject, scope, validFrom, validUntil, signature, verificationScheme, verificationMaterial) |
| commitment* | any | The commitment or requested action the proof must authorize |

}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_commitments.
| Argument | Type | Description |
|---|---|---|
| commitmentId* | string | The commitment id (0x-prefixed or agent-id style) to look up |

}
}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, or stop. For the full commitment record, use get_commitment.
| Argument | Type | Description |
|---|---|---|
| commitmentId* | string | The commitment id to poll for its lifecycle state |

}Verifies external evidence against a commitment's acceptance criteria. Requires an active SAAX Premium subscription. For authority proof validation, use get_authority_validation.
| Argument | Type | Description |
|---|---|---|
| evidence* | any | The evidence object (evidenceId, evidenceType, issuer, subject, payload, payloadHash, signature, verificationScheme, commitmentId, acceptanceCriterionId, ...) |
| criterion* | any | The verification policy / acceptance criterion |
| commitment* | any | The commitment object the evidence binds to |

}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.
No arguments.
{

}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.
No arguments.
{
"type": "object",
"$schema": "http://json-schema.org/draft-07/schema#",
"properties": {}
}Returns the capabilities currently indexed by the SAAX Router, with supplier counts per capability. Call this to discover what can be routed. For pricing of a specific capability, use get_routing_fee. For protocol overview, use get_protocol_info.
No arguments.
{
"type": "object",
"$schema": "http://json-schema.org/draft-07/schema#",

|---|---|---|
| subscriptionEmail* | string | The subscription email (must have an active SAAX Premium subscription) |

No arguments.

}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.
| Argument | Type | Description |
|---|---|---|
| budget | number | Maximum budget in USDC the buyer will pay |
| deadline | number | Deadline in seconds from now for delivery |
