| x402_discoverA | Search for x402 paid API endpoints that can answer a question or provide data. Discovery powered by Decixa (5,500+ verified x402 endpoints) with local registry fallback. Searches across the entire x402 ecosystem — not just Alderpost endpoints. Local registry includes premium endpoints backed by VirusTotal, People Data Labs, Hunter.io, AbuseIPDB, Qualys SSL Labs, NIH RxNorm, US Census Bureau, OpenWeather, The Odds API. Categories: security, company/business, threat intelligence, sales/leads, compliance, health/drug, property/location, sports, and any x402 capability indexed by Decixa. Examples:
Use x402_call to call any discovered endpoint. |
| x402_callA | Call any x402 paid API endpoint with automatic USDC payment via AgentCash. Accepts a full URL with query parameters. Handles the complete x402 payment flow:
Requires AgentCash wallet to be set up and funded (https://agentcash.dev). Examples:
|
| x402_balanceA | Check your AgentCash USDC wallet balance on Base. Returns current balance available for x402 payments and approximate number of calls you can afford. No parameters required. If AgentCash is not set up, provides instructions to create and fund a wallet. |
| x402_researchA | Run comprehensive research by calling multiple x402 endpoints in parallel. Given a subject (domain, IP, address, drug name, or sport), this tool:
This is the fastest way to get a complete intelligence picture on any subject. Input types (auto-detected):

Scored across 4 tools
Each tool has a clearly distinct purpose: checking balance, making a single payment-supported call, discovering endpoints, and running parallel research. No overlap or ambiguity.
All tools follow the 'x402_<action>' pattern with consistent lowercase and underscores. The actions are all verbs except 'balance', which is a noun but commonly understood as a verb in API contexts.
Four tools are exactly appropriate for the server's purpose. Each tool is essential and none feel redundant or missing.
The tool surface covers the full workflow: discover endpoints, check balance, call an endpoint, and run multi-endpoint research. No obvious gaps for the stated purpose of interacting with x402 APIs.
