audit_agent_visibility

AEO/GEO Agent Visibility Auditor. Audit any third-party API endpoint for x402 compatibility, schema compliance, robots.txt indexing accessibility, and LLM tool calling clarity. [PAID: $0.75 USDC per call via x402 on Base. First call without payment_signature returns the payment requirements.]

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
urlYesTarget API endpoint URL to check
payment_signatureNoOptional x402 payment token. Call the tool WITHOUT this first to receive payment requirements (price, payTo, asset, nonce rules), sign the exact-scheme EIP-712 USDC authorization with your wallet, then retry with this field set to the base64 token.

TDQS

A4.5/5.0
Behavior4/5

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

With no annotations, the description discloses the paid nature, first-call behavior to get payment requirements, and the audit scope. Lacks details on response format or failure modes, but adequately informs the agent of key behavioral traits.

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?

Two sentences, no filler. First sentence states purpose, second explains payment mechanism. Front-loaded and efficient.

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?

Covers the tool's purpose and payment process well. Without an output schema, the agent has enough to invoke it correctly. Minor missing details like expected response structure are acceptable given the tool's simplicity.

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

Parameters5/5

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

Schema descriptions are already detailed (100% coverage), but the description adds value by stating the cost ($0.75 USDC) and clarifying the payment flow with x402 on Base, which goes beyond the schema's parameter descriptions.

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?

Description clearly states it audits third-party API endpoints for specific criteria like x402 compatibility and schema compliance. The resource (Agent Visibility Auditor) is well-defined and distinct from sibling tools which are mostly data retrieval tools.

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

Usage Guidelines4/5

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

Explicitly explains the two-step payment process and provides context for when to call (to audit an endpoint). Could be improved by mentioning when not to use, but the paid nature and sibling context make it clear.

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

A3.9/5.0
Disambiguation4/5

Most tools have distinct purposes, but get_crypto_prices overlaps partially with get_market_pulse (which includes crypto prices), and get_exchange_rates overlaps with convert_currency. Descriptions clarify boundaries, but minor confusion possible.

Naming Consistency4/5

Nearly all tools follow a get_<noun> or verb_noun pattern, with consistent snake_case. The only outlier is 'health' which is a single word, but it still fits as a status endpoint.

Tool Count4/5

22 tools is slightly high for a single server, but each tool offers a distinct paid endpoint and the variety justifies the count. The server would benefit from a bit more focus, but it's still acceptable.

Completeness4/5

The server covers a wide range of data (crypto, weather, finance, on-chain risk, travel) with search and health endpoints. Missing operations like delete_watch or list_watches are minor gaps, but core functionality is well represented.
