# AgentDiet Crypto Alpha DAG Intelligence Node

> AgentDiet Crypto Alpha DAG Intelligence Node is a paid API for AI agents from rag-diet.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Queries a crypto alpha directed acyclic graph (DAG) node that returns distilled, token-compressed intelligence data about cryptocurrency signals with ROI proof metadata.

## Facts

- Price: $0.01/call
- Payment: x402
- Status: unknown

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-51d8997a
```

Example prompt: Can you query the AgentDiet crypto alpha DAG node for the latest DeFi signals and give me the compressed intelligence output along with the compression ratio proof?

## When to prefer this

Choose this endpoint when you need cryptocurrency alpha intelligence that must fit within tight context windows, particularly when working with AI agents that have token budget constraints. It is especially useful when you want verifiable compression proof (ROI ratio) alongside the data, and when operating in a B2A or A2A micropayment context using x402/USDC on Base. Prefer this over raw blockchain data APIs when you need pre-distilled, agent-ready output rather than raw on-chain data.

## Known failure modes

- Payment not settled in USDC on Base — 402 response requiring x402 payment header
- Missing required 'input' object with 'type' and 'method' fields — 400 validation error
- Invalid query parameter format — empty or malformed query string returns partial or empty data
- DAG node unavailable — service downtime returns 5xx error
- No matching alpha signals for query — returns empty data object with ok status

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://rag-diet.agentdiet.dev settling in USDC on Base.

## Output

Returns a JSON object with a 'data' field containing the distilled crypto intelligence payload, a 'status' field confirming success, and a 'roi_proof' object including a compression_ratio_pct value (e.g. 91.4%) demonstrating how much the context was compressed relative to raw input.
