How this service works
Signed data for AI agents, paid per call over x402. Hyperliquid crowd state, smart money and liquidations with what historically happened next, plus independent checks of x402 services and MCP servers.
Output
Returns a JSON object containing the server's registry name, an overall quality grade (e.g. 'A'), tool count, tool changes over the past 30 days, access mode (open/paid), protocol version, median response time in milliseconds, and 7-day uptime share as a fraction.
Example use cases
Vetting an MCP server before adoption
“Before I wire up io.github.acme/data-tools into my agent pipeline, can you pull its Annalist grade and tell me if the uptime is solid and how many tools it exposes?”
Comparing MCP server reliability
“I'm deciding between two MCP servers — can you check the Annalist quality grade and median latency for io.github.teamA/analytics-server so I can compare it against what I already know about the other one?”
Monitoring a deployed MCP server
“Can you grab the latest Annalist reliability report for https://mcp.mycompany.com — specifically the 7-day uptime share and whether the tool list has changed in the past 30 days?”
Technical details
Endpoint
GEThttps://api.annalist.dev/v1/mcp/server?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need an independent, signed third-party assessment of an MCP server's quality, reliability, and tooling before integrating it into an agent workflow. Prefer it over self-reported server metadata when trust and uptime verification matter, especially for x402-paid services.
Side effects
- Unknown server URL or registry name returns an error or empty result
- Server not yet indexed by Annalist returns no data
- Invalid query parameter format causes a 400 error
- Payment not completed via x402 results in a 402 response blocking access
- Newly launched servers may have insufficient history for reliability metrics
