x402 trust leaderboard (free)

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

Describes the ranking factors (uptime, envelope compliance, latency, age, on-chain settlement activity, price stability) but does not specify data freshness, pagination, or output format. With no annotations, the description provides moderate behavioral context.

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

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

Two sentences with no wasted words. The first sentence is front-loaded with the core purpose and the second provides a usage hint.

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

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

Describes the output as top-25 endpoints and ranking criteria, but lacks details on output fields or structure. Since there is no output schema, the description should provide more completeness about what the returned data contains.

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

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

No parameters exist, and schema coverage is 100%. Baseline score of 4 is appropriate as the description does not need to add parameter information.

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

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

Clearly states the tool returns the top-25 most trustworthy x402 endpoints, ranked by a deterministic trust score. Distinguishes from sibling tools by focusing on a leaderboard.

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

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

Explicitly suggests using it to discover reliable paid endpoints, providing context on appropriate usage. Does not explicitly contrast with sibling tools but the purpose is clear.

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