# AgentDiet Crypto Alpha DAG Intelligence Node

> AgentDiet Crypto Alpha DAG Intelligence Node 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).

Queries a crypto-alpha intelligence DAG endpoint that returns compressed, high-signal cryptocurrency data via a paid x402 API gateway.

## Facts

- Endpoint: GET https://mcp-gateway.agentdiet.dev/v1/crypto-alpha-dag?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-crypto-alpha-dag-intelligence-node-a1452818
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_lfJRGMznNTpeCAz6nalmK

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-crypto-alpha-dag-intelligence-node-a1452818
```

Example prompt: Search the crypto alpha DAG for high-signal intelligence on Ethereum using a GET query and show me what compressed insights come back.

## When to prefer this

Choose this endpoint when you need compressed, high-signal crypto alpha data delivered via a deterministic x402 micropayment flow on Base network, especially when you want ROI-proof compression metrics alongside the intelligence payload. Prefer over generic crypto data APIs when operating in an autonomous agent context that supports x402 payment headers.

## Known failure modes

- Missing or invalid 'input' object returns schema validation error
- Payment not received returns HTTP 402 with payment required details
- Invalid method enum value (not GET or POST) returns validation error
- Empty or missing query param returns minimal or empty data payload
- Network or gateway timeout returns no response

## 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

Returns a JSON object with a 'data' field containing the crypto alpha payload, a 'status' field (e.g. 'ok'), and a 'roi_proof' object including a compression_ratio_pct metric (e.g. 91.4%), indicating how much the raw data was compressed.
