How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.
Output
A JSON object with a 'data' field containing the narrative tracking payload, a 'status' field indicating success ('ok'), and an 'roi_proof' object that includes a 'compression_ratio_pct' value (e.g. 91.4%) demonstrating the efficiency of the data compression applied.
Example use cases
Monitor brand narrative shifts
“Track the current narrative around our brand domain 'mybrand.com' and tell me what the intelligence snapshot looks like, including how compressed the data is.”
Agent pipeline ROI verification
“Fetch the narrative tracker results for target 'openai.com' so I can verify the compression ratio and confirm the data quality before passing it downstream in my agent workflow.”
Topic narrative status check
“What's the latest narrative status for the topic 'AI regulation' — pull the compressed snapshot and show me the ROI proof so I know how efficient the data retrieval was.”

Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/narrative-tracker?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pay-per-call, cryptographically-settled narrative intelligence pull with built-in compression ROI proof, especially within an x402-native agent pipeline that already settles in USDC on Base. It is well-suited for lightweight agent workflows that need structured narrative snapshots without committing to a subscription or heavy data contract.
Side effects
- Missing or invalid 'target' query parameter results in empty or generic data response
- Payment not settled in USDC on Base causes HTTP 402 and request rejection
- Invalid 'type' or 'method' values in input object cause schema validation failure
- Target URL unreachable or unrecognized may return empty 'data' object with status 'ok' but no meaningful payload
- Rate limiting or gateway overload may produce timeout or 5xx errors
