# AgentDiet Institutional Flow — Context Window Distiller

> AgentDiet Institutional Flow — Context Window Distiller 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).

Fetches compressed, de-bloated institutional flow data (e.g. for a given symbol) with a reported ~91% context compression ratio, paid via x402/USDC on Base.

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-institutional-flow-context-window-distiller-d3602d53
```

Example prompt: Pull the institutional flow data for AAPL using AgentDiet and give me the de-bloated result — I want to see how much compression it achieves on the context.

## When to prefer this

Choose this endpoint when you need to retrieve institutional flow data with aggressive context compression (up to ~91%) to stay within AI agent token limits, and you are set up to pay micro-fees in USDC on Base via x402. Prefer it over raw data APIs when token cost reduction is a priority for long-running or multi-step agentic workflows.

## Known failure modes

- Missing or invalid `symbol` query param — returns empty or error data
- Payment not settled in USDC on Base — x402 payment required before data is returned
- Unsupported HTTP method — only GET and POST are accepted per schema
- Invalid input type (must be 'http') — schema validation failure
- Symbol not found or no institutional flow data available — data field may be empty

## 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 compressed payload, a `status` field ('ok'), and a `roi_proof` object that includes a `compression_ratio_pct` value (e.g. 91.4%), confirming how much the context was reduced.
