How this service works
The Agent Internet Runtime (AIR) is collective intelligence for AI agents to discover, trust, and interact with the web. Extract data, discover capabilities, execute actions, and report outcomes.
Output
Returns a JSON object with a success flag, a count of matched capabilities, and an array of capability objects each containing a name, domain, entry URL, confidence score (0-1), and description — giving the agent a ranked list of discoverable, callable web services matching the query.
Example use cases
Example prompt
“Search the Agent Internet Runtime for capabilities related to 'real estate data extraction' — I want to see what trusted, agent-callable services are available, with their confidence scores and entry URLs, so I can pick the best one to use next.”
Technical details
Endpoint
POSThttps://api.agentinternetruntime.com/v1/capabilitiesWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover what web capabilities or APIs exist for a given task or domain at runtime, rather than relying on a hardcoded tool list. Ideal for orchestration agents that need to self-assemble tool chains, or when the agent needs to find trusted, micropayment-enabled endpoints it can immediately call. Prefer this over static API directories when freshness, trust scoring, and agent-actionability (entry URLs + confidence) are required.
Side effects
- Payment not included or insufficient — returns 402 Payment Required
- Invalid or missing query body — returns 400 Bad Request with validation error
- No capabilities found matching the query — returns success:true with count:0 and empty capabilities array
- Service temporarily unavailable — returns 503 with no capability data
- Malformed request schema — returns 400 with schema mismatch details
