# AgentDiet MCP Gateway – CS-LG Digest Endpoint

> AgentDiet MCP Gateway – CS-LG 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-signal digest of computer science and machine learning content via a query parameter, settling payment in USDC on Base.

## Facts

- Endpoint: GET https://mcp-gateway.agentdiet.dev/v1/cs-lg-digest?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-22
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/agentdiet-mcp-gateway-cs-lg-digest-endpoint-f2c4d090
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_jzk7Kcxxn1DGPqZCIo6G4

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-mcp-gateway-cs-lg-digest-endpoint-f2c4d090
```

Example prompt: Can you pull me a compressed CS and ML digest from AgentDiet for the query 'transformer architectures 2024' — I want the high-signal summary with the compression proof?

## When to prefer this

Choose this endpoint when you need a pre-compressed, high-signal digest of computer science and machine learning content rather than raw search results or full documents. It is especially useful when token efficiency matters and you want proof of compression (ROI proof). Prefer it over general web search when you need curated CS/ML academic-style summaries settled via x402/USDC micropayments.

## Known failure modes

- Missing required 'input' object returns a validation error
- Invalid method enum value (not GET or POST) causes schema rejection
- Empty or missing query parameter returns generic or empty digest data
- Payment failure (insufficient USDC on Base) results in 402 response blocking content
- Unavailable upstream MCP servers may return partial or empty data payload

## 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 containing a data payload with the digest content, a status field ('ok'), and an roi_proof object including a compression_ratio_pct value (e.g. 91.4%) indicating how much the source material was compressed.
