How this service works
Continuously check whether AI agents can discover, call and pay your API, MCP server or x402 service. Free live checks and GitHub Action monitoring.
Output
Returns the best-matched verified service or endpoint for the stated goal, including routing details and execution guidance so the agent knows which capability to invoke and how.
Example use cases
Auto-select tool for agent task
“My agent needs to transcribe audio files but I'm not sure which service to use — can you resolve the best verified capability for transcribing audio and tell me how to call it?”
Goal-based API routing
“I want my agent to send an SMS notification to a user — resolve which verified service it should call to accomplish that goal.”
Unknown capability discovery
“My agent has a goal of converting a PDF to structured data but I haven't wired up any tool for that yet — use AgentResolver to find and recommend the right verified service.”
Technical details
Endpoint
POSThttps://agentresolver.vercel.app/api/verified-resolve?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover or select among multiple machine services for a given goal at runtime, rather than having a hardcoded tool. Especially useful for general-purpose agents that encounter novel tasks and need capability routing without pre-wiring every possible API.
Side effects
- Ambiguous or underspecified goal leads to low-confidence or incorrect match
- No verified service exists for the stated goal, returning empty or null result
- Optional URL hint is malformed or unreachable, degrading routing accuracy
- Payment of $0.02 USDC not fulfilled, resulting in 402 Payment Required response
- Service returns a mismatch if the goal description is too broad or too narrow
