How this service works
What came back for a paid agent call, written down: every x402 endpoint and remote MCP server we watch, and every call we paid for.
Output
A JSON research brief containing recorded response data from paid calls to tracked x402 endpoints and remote MCP servers, including details about what was returned, endpoint metadata, and call history as logged by Teppi.
Example use cases
Evaluate unknown x402 endpoint before paying
“Before I commit to paying for calls to that x402 weather API, can you pull a Teppi research brief so I can see what kind of data it actually returned in past paid calls?”
Audit MCP server response history
“I need to review what our remote MCP server at mcp.myagent.dev has been delivering — can you get a Teppi research brief summarizing the recorded responses from paid calls to it?”
Compare two paid API endpoints
“I'm trying to decide between two x402 endpoints for financial data — can you fetch Teppi research briefs for both so I can compare what they actually returned to paying callers?”
Technical details
Endpoint
POSThttps://api.teppi.xyz/v1/research/brief?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to inspect what a paid x402 API or remote MCP server actually returns before or after calling it yourself — especially useful for discovery, due diligence, or auditing recorded agent interactions in the x402 ecosystem. Prefer this over generic API documentation lookups when you want ground-truth delivery records from real paid calls rather than synthetic descriptions.
Side effects
- Endpoint or topic not found in Teppi's tracked dataset — returns empty or null brief
- Payment of $0.02 USDC not processed — call rejected with 402 status
- Malformed POST body — returns validation error
- Endpoint has no recorded paid call history yet — brief may be sparse or missing fields
