Agent Invoice Rail

Destructive

Paid URL: 0.10 USDC per call on Base; 10 signed-wallet free calls shared over rolling 30 days. Read the backend 402 body for x402 terms. Private issuer-wallet invoice ledger, immutable face amount and parties, run-reference binding and recorded issuer review. References are not independently verified. No bill delivery, payment collection or spending authority. Operating boundary: Direct access uses x402 Base USDC settlement or the verified-wallet free tier. Private issuer-wallet invoice ledger, immutable face amount and parties, run-reference binding and recorded issuer review. References are not independently verified. No bill delivery, payment collection or spending authority. Every invoice operation also requires a signed issuer-wallet ownership proof. The API access fee is separate from any inspected payment or recorded invoice amount. POST /api/agent-invoice-rail. Existing product credentials, signed mandates, and single-use action grants remain required where applicable. This adapter grants no authority and never supplies server credentials. This current money service follows its published inspection, policy evaluation or private invoice contract. Payment is an API access fee and grants no spending authority.

C2.7/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond the annotations, the description discloses the paid-access model and price, the free tier, the 402 term lookup, the mandatory ownership proof, and explicit non-capabilities ('No bill delivery, payment collection or spending authority', 'References are not independently verified'). That is meaningful behavioral context an agent cannot get from the destructiveHint/readOnlyHint flags alone.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The same key phrases ('Private issuer-wallet invoice ledger, immutable face amount and parties, run-reference binding and recorded issuer review', 'No bill delivery, payment collection or spending authority') are repeated verbatim in the opening and the 'Operating boundary' block, wasting the most valuable positional real estate on duplication rather than new information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 4-mode, 15-parameter, nested-object tool with no output schema and only coarse annotations, the description is insufficient: the payable flow, mode dispatch, idempotency behavior, and expected versioning are all undisclosed. Payment and authority boundaries are covered, but the operational core is not.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 15 parameters, nested run_binding, and 0% schema description coverage, the description carries the full burden but explains almost nothing about parameters. 'Immutable face amount and parties' and 'run-reference binding' loosely gesture at amount_atomic/buyer_wallet/run_binding, but no parameter names, formats, enum meanings (synthetic vs operational, approve vs reject), idempotency, or version semantics are clarified.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description identifies a specific resource ('Private issuer-wallet invoice ledger') and differentiates from sibling rails (escrow-lite, work-order-rail) by being invoice-focused, but the four operations (create/read/bind/review) are never surfaced even though they are the core of the schema. The purpose is recognizable but the tool's multi-mode nature is left entirely opaque.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It states access mechanics (x402 Base USDC settlement, 10 free signed-wallet calls, signed issuer-wallet ownership proof required) but gives no when-to-use guidance, no mode-selection guidance, and no comparison against sibling tools such as escrow-lite or work-order-rail. Nothing tells the agent which of the four modes to invoke for a given intent.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
