Get market cap, 24h volume, ATH, and price change for any token. Note: does NOT return pool depth or slippage — for pre-trade liquidity estimates, use a dedicated orderbook tool.
AI agents call token_market_data to retrieve information from AgentPay x402 — Economic-intelligence layer for AI Agents without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
token_market_data purely queries and returns immutable market statistics. It neither executes trades, modifies blockchain state, moves funds, nor triggers external operations. The information retrieved is informational only and cannot be weaponized by an agent for unauthorized financial activity; it requires downstream tools for actual execution.
From the tool's definition Tool description states it 'Get[s] market cap, 24h volume, ATH, and price change' — all retrieval operations with no side effects. Explicitly clarifies it 'does NOT return pool depth or slippage' and directs users to other tools for actionable trading data.
Attacks that exploit this kind of access
Get market cap, 24h volume, ATH, and price change for any token. Note: does NOT return pool depth or slippage — for pre-trade liquidity estimates, use a dedicated orderbook tool. It is categorised as a Read tool in the AgentPay x402 — Economic-intelligence layer for AI Agents MCP Server, which means it retrieves data without modifying state.
Register the AgentPay x402 — Economic-intelligence layer for AI Agents MCP server in PolicyLayer and add a rule for token_market_data: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches AgentPay x402 — Economic-intelligence layer for AI Agents. Nothing to install.
token_market_data is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the token_market_data rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for token_market_data. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
token_market_data is provided by the AgentPay x402 — Economic-intelligence layer for AI Agents MCP server (romudille-bit/agentpay). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
token_market_data is one line of AgentPay x402 — Economic-intelligence layer for AI Agents's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
