How this service works
Describe what you need and get back matching x402-paid APIs: our own catalog (54 tools) plus, optionally, the live x402 Bazaar of third-party sellers. The agent's meta-tool — instead of knowing an API exists, ask for the capability. Use this when an agent needs to "I need a tool that does X" → matched paid APIs.
Output
A list of matched API tools from the AgentTools catalog (54 tools) and optionally the live x402 Bazaar, each entry including the tool name, description, pricing, and endpoint details relevant to the requested capability.
Example use cases
Dynamic tool discovery for agent pipelines
“I need to find an API that can validate IBAN bank account numbers — search the AgentTools directory including Bazaar results and show me the top 3 matches.”
Exploring available paid APIs by capability
“What x402-paid APIs are available for extracting text from documents or PDFs? Search the AgentTools catalog and limit results to 5.”
Building an agent that self-selects its tools
“My agent needs a tool that can convert currencies in real time — can you search the AgentTools directory (Bazaar included) and return up to 10 matching APIs?”
Technical details
Endpoint
GEThttps://agentstoolshub.com/api/v1/dev/directory-search?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent does not know which specific API to call and needs to discover available paid tools by describing the capability it requires. It is the meta-tool for dynamic tool discovery within the x402 ecosystem, especially useful for agentic pipelines that self-assemble their toolchain at runtime rather than relying on hardcoded API integrations.
Side effects
- Missing required 'query' parameter returns a validation error
- Empty results when no tools match the capability description
- Bazaar unavailable or slow when includeBazaar=true, potentially causing timeout
- Malformed query string may return irrelevant or zero results
- x402 payment failure prevents the request from being processed
