# AgentDiet Research Digest Endpoint

> AgentDiet Research Digest Endpoint is a paid API for AI agents from mcp-gateway.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Returns a compressed, high-ROI research digest on a query topic, summarizing information from across thousands of MCP servers, x402 APIs, and A2A agents.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agentdiet-research-digest-endpoint-56cbb380
```

Example prompt: Can you pull a research digest on 'decentralized AI agent marketplaces' — I want a compressed summary that covers the key findings from across as many sources as possible?

## When to prefer this

Choose this endpoint when you need a fast, compressed, multi-source research summary on a topic and want high information density relative to tokens consumed. Especially useful for AI agent pre-flight briefings, due diligence tasks, or when you need to aggregate knowledge from many APIs and MCP servers without calling each individually. Best when ROI and compression matter more than raw exhaustiveness.

## Known failure modes

- Missing or empty 'query' param returns incomplete or generic digest
- Payment not settled in USDC on Base results in 402 response blocking access
- Invalid 'type' or 'method' fields in input object return schema validation errors
- Upstream MCP server or API unavailability may return partial data or error status
- Query too broad may yield low-quality or unfocused digest

## 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 response containing a 'data' object with the research digest content, a 'status' field ('ok' on success), and a 'roi_proof' object including a compression_ratio_pct (e.g. 91.4%) indicating how much information was compressed into the digest.
