Browse high-volume agent credit packages and x402 enterprise services

list_premium_agent_packs

Read-onlyIdempotent

Use this free catalog only when an authorized agent needs a high-volume one-time Base USDC credit pack ($99.90–$2,499.90) or high-ticket seller-payment and portfolio x402 analysis. Includes exact prices, proof links and safe per-pack checkout URLs. Before any spend use quote_premium_workload for planned credit usage or quote_premium_delivery for a real ledger/workspace input. For small workloads use list_products or per-call x402 instead. The catalog never signs, issues invoices, subscribes, or buys.

A4.4/5.0

Behavior4/5

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

Annotations already declare a safe read operation, but the description adds real behavioral context beyond them: it clarifies that listed checkout URLs do not mean the catalog transacts ('never signs, issues invoices, subscribes, or buys'). It also discloses that prices are exact and includes proof links. It stops short of describing pagination or result shape, so not a full 5.

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

Conciseness5/5

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

Four tight sentences, each carrying distinct load: scope/trigger, contents, quote step, and alternatives, then the non-transactional guarantee. The gating condition ('Use this free catalog only when...') is front-loaded with zero filler.

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

Completeness4/5

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

Given a single-parameter read-only catalog with no output schema, the description tells the agent what it returns (exact prices, proof links, per-pack checkout URLs) and, importantly, the quote-before-spend workflow. It is complete enough to call correctly; only the return structure is left implicit, which is acceptable without an output schema.

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

Parameters3/5

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

Only one optional parameter (max_spend_usd) exists and its schema description already covers it fully (100% coverage). The description reinforces the no-purchase constraint but adds no syntax or format detail beyond the schema, so the baseline 3 is appropriate.

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

Purpose5/5

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

States a specific verb and resource (browse a free catalog of high-volume Base USDC credit packs and x402 services) and pins the scope with a concrete price band ($99.90–$2,499.90). It explicitly contrasts itself with the sibling list_products, so an agent can route between them without opening either schema.

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

Usage Guidelines5/5

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

Gives an explicit when-to-use condition (high-volume one-time packs or high-ticket seller-payment/portfolio x402 analysis) plus named alternatives: quote_premium_workload for planned usage, quote_premium_delivery for a real ledger input, and list_products / per-call x402 for small workloads. Both the trigger and the exclusions are spelled out.

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