What it can do
| Tool | What it says it does |
|---|---|
check_token | Before your agent buys a Base token: can it sell it back? A simulated buy and immediate sale on the deepest pool (honeypot and tax detection, Uniswap v4 hooks included), real sales on that pool, owner and admin powers, real liquidity. No address: the free sample. An address: its price ($0.01 over… |
check_x402_service | Before your agent pays an x402 service: its grade and finding codes, measured from its payments on Base (detailed: true for the full report with evidence). No url: the free sample. A url: the price and how to pay over x402. |
dispute_finding | Dispute a finding in one of Blackhull's x402 service reports. Free. It is rechecked from fresh data on the next daily run and upheld or withdrawn; every outcome is public at /disputes. |
economy_movers | This week's fastest-moving agent repositories on GitHub (star deltas) and newly seen MCP servers. |
find_provider | The best-rated paid providers for a job within a budget, ranked from measured payments (neutral: Blackhull is never ranked). No capability: the free sample. A capability: the price and how to pay over x402. |
request_capability | Could not find a tool or data source you need? Say what it is and the most you would pay per call (USDC). Free. Stored only as a short label — do not include personal data. Returns the closest paid services Blackhull sees, if any. |
search_mcp_servers | Search MCP servers published or updated this week by name; each has a purpose label (read/act/transact) and whether it charges agents per call. |
what_agents_want | The three-scale summary: why AI crawlers fetch (Cloudflare Radar), what tools are being built for agents (by purpose), and which agents visit blackhull. |
In its maker's words
Before your agent buys a Base token: can it sell it back? Plus x402 service grades and providers.
