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 array of ranked provider objects, each with a URL, numeric rank, quality grade (e.g. CLEAN), number of payers, and the price actually paid per call — all scoped to the requested capability category.
Example use cases
Cheapest LLM inference for budget agent
“I'm building an agent on a tight budget — can you use Blackhull to find the top-rated llm-inference providers that cost no more than $0.004 USDC per call?”
Routing agent to best search API
“My agent needs to pick a search provider — pull the Blackhull ranking for the best search APIs so I can route to the #1 graded one.”
Vetting onchain data sources
“I want to use only clean, trusted onchain data services — can you check Blackhull for the top-rated onchain providers and show me their grades and how many agents have paid them?”
Technical details
Endpoint
GEThttps://blackhullsystems.com/route?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover and route to the best available x402-compatible API provider for a given capability (ai-analysis, llm-inference, search, etc.) rather than hardcoding a provider. Especially useful when cost is a constraint and you want pre-vetted, ranked, graded results from actual payment history.
Side effects
- Unknown or unsupported capability category returns empty or error response
- max_price filter set too low returns no matching providers
- Stale rankings if Blackhull snapshot date (2026-10-30) is not refreshed
- Network timeout if blackhullsystems.com is unreachable
- Malformed queryParams (missing required capability field) returns 400-style error
