# AgentDiet Broker Catalog — Intelligence Node Directory

> AgentDiet Broker Catalog — Intelligence Node Directory 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).

Returns the catalog of available intelligence nodes and capabilities offered by the AgentDiet context-distillation broker network

## Facts

- Endpoint: GET https://rag-diet.agentdiet.dev/v1/broker/catalog?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-broker-catalog-intelligence-node-directory-f3a8a054
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_vvOHhbie0xGDvx8App5jG

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-broker-catalog-intelligence-node-directory-f3a8a054
```

Example prompt: Pull up the AgentDiet broker catalog so I can see what intelligence nodes and context-distillation capabilities are currently available on the network.

## When to prefer this

Use this endpoint when an AI agent needs to discover what context-compression, token-reduction, or intelligence-node capabilities are available in the AgentDiet broker network before invoking a specific node. It is the discovery/catalog layer, not an execution endpoint. Prefer this over direct node calls when you don't yet know which node to use or want to enumerate available options.

## Known failure modes

- Payment not settled — returns HTTP 402 if USDC payment on Base is not included or fails
- Invalid query params — malformed queryParams object returns an error
- Network unavailability — the broker node may be temporarily offline
- Empty catalog — data object may be empty if no nodes are registered

## 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 status field ('ok'), a data object containing the broker node catalog entries, and an roi_proof object showing the compression ratio percentage (e.g. 91.4%) achieved by the network's distillation capabilities.
