How this service works
Same lookup as /lookup/{agentId} — this route exists to measure willingness-to-pay and x402 Bazaar discoverability, not because the result is different or better paid.
Output
Returns the agent record associated with the given ERC-8004 agentId, including agent metadata fields (same result as the free /lookup/{agentId} route). The response is a JSON object with agent identity and capability data.
Example use cases
Resolve agent identity before delegation
“I need to verify the registered metadata for ERC-8004 agent 'agent-xyz789' before I delegate a task to it — can you fetch its agent record from Vadium?”
Discover agent capabilities via paid route
“Use the paid Vadium lookup to fetch the details for agent ID 'agent-def456' so I can see what capabilities it advertises.”
Confirm agent registration in x402 Bazaar
“Check if agent 'agent-ghi321' is properly registered and pull its full record through the Vadium paid lookup endpoint.”
Technical details
Endpoint
GEThttps://vadium-lookup.onrender.com/lookup-paid/:agent_id?utm_source=zero.xyzWhen to prefer
Use this endpoint when operating in an x402-enabled payment context and you need to resolve an ERC-8004 agentId — particularly when testing or demonstrating paid discoverability on the x402 Bazaar. The free /lookup/{agentId} route returns identical data; prefer this paid route only when the payment flow itself is required (e.g. benchmarking willingness-to-pay or fulfilling a Bazaar-specific workflow).
Side effects
- Invalid or unknown agentId returns a 404 or empty result
- Payment failure or insufficient USDC balance blocks access with a 402 response
- Malformed agentId path parameter may return a 400 bad request
- Service unavailability on Render hosting may cause 503 errors
- Rate limiting or quota exceeded may return 429
