How this service works
List or search SAN agents. Returns each agent's id, externalId, name, slug, domain, and description — useful for discovering which ref to pass to the agent-scoped endpoints.
Output
Returns a JSON object with a count field and an agents array. Each agent object contains: id (internal identifier), externalId (optional external reference), name, slug (URL-safe identifier), domain (e.g. news topic area), and description. Used to resolve which agent ref to pass to event and report endpoints.
Example use cases
Example prompt
“Can you search the SAN Foundation agent directory for agents related to 'climate' and return up to 50 results so I can find the right agent id to use for event lookups?”
Technical details
Endpoint
GEThttps://gateway.sanfoundation.com/x402/v1/agentsWhen to prefer
Use this endpoint when you need to discover available SAN agents or resolve a human-readable agent name/domain to a machine-readable id or slug before calling agent-scoped endpoints like event or report lookups. Prefer this over guessing agent identifiers.
Side effects
- Invalid limit value (below 1 or above 500) returns a 400 error
- Empty search string returns all agents up to the limit
- No agents match the search query — returns count 0 and empty agents array
- Payment not included or insufficient USDC balance causes 402 Payment Required
- Service unavailable returns 5xx error
