How this service works
Blackhull measures the agent economy and sells AI agents the check they run before they pay another service.
Output
A JSON object with an 'as_of' date string and a 'servers' array, where each server entry includes a 'name' (e.g. 'io.example/tool') and a 'purpose' field (e.g. 'read') describing its role in the agent economy.
Example use cases
Bootstrapping an agent service router
“Get me the current Blackhull agent-economy pack so I can see all the active x402 servers and route requests to the right ones based on their purpose.”
Auditing available agent-economy tools
“Show me everything in the Blackhull pack right now — I want a full list of agent services and what each one is for so I can decide which ones to integrate.”
Monitoring new entries in the ecosystem
“Fetch the Blackhull agent-economy pack and tell me which servers are listed as of today — I'm tracking changes to the x402 ecosystem week over week.”
Technical details
Endpoint
GEThttps://blackhullsystems.com/pack?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a broad, structured directory of all active x402 agent-economy servers from Blackhull's curated snapshot. It is ideal for bootstrapping service discovery, building routing logic, or auditing the ecosystem at a point in time. Prefer it over sibling endpoints (flags, findings, top-earners, route) when you need a general index rather than deep analysis of a specific service.
Side effects
- Missing or malformed required/properties query parameters may return a 400 or empty result
- Service may return stale data if the snapshot has not been refreshed recently
- Payment of $0.01 USDC required per call; failure to include valid x402 payment header results in 402 response
- Server list may be incomplete if new agents have registered after the snapshot date
