How this service works
Agent Registry discovery ($0.01/request direct, or $0.003/request via Session Ticket at /v1/billing/tickets)
Output
Returns a success flag and a data object containing: a count of matched agents, an array of agent objects each with id, name, score, payment details, reputation metadata, and description; plus a list of capabilities_without_agents showing domain, source, capability name, confidence, description, trust score, and execution tier for unagented capabilities.
Example use cases
Example prompt
“Search the Agent Internet Runtime registry for up to 10 agents that can handle real-time cryptocurrency price lookups, sorted by best_value, in the finance domain.”
Technical details
Endpoint
POSThttps://api.agentinternetruntime.com/v1/registry/discoverWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover other agents or capabilities at runtime based on a natural language intent, especially when the right downstream service is not known in advance. Prefer this over hardcoded service lookups when the agent ecosystem is dynamic or when cost/speed/reliability tradeoffs need to be made at query time.
Side effects
- Invalid sort enum value returns 400 validation error
- limit exceeding 50 returns 400 bad request
- Missing or empty intent results in low-relevance or empty agent list
- Payment failure (402) if no valid x402 session ticket or direct payment provided
- Network timeout if registry is slow to respond
- No agents found returns empty agents array with count 0
