# AgentDiet RAG Diet Context Window Distiller

> AgentDiet RAG Diet Context Window Distiller is a paid API for AI agents from rag-diet.agentdiet.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-22).

Compresses and distills AI context windows or web content via a paid endpoint, reducing token usage by up to 91% while preserving semantic meaning.

## Facts

- Endpoint: GET https://rag-diet.agentdiet.dev/paid?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-22
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/agentdiet-rag-diet-context-window-distiller-1098d2f8
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_AWo-fj56zJOWK7K_jV4Y2

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-rag-diet-context-window-distiller-1098d2f8
```

Example prompt: Can you use AgentDiet to compress the content at https://example.com/longdoc so it fits in my context window? Use GET mode to fetch and distill it.

## When to prefer this

Choose this endpoint when you need to deterministically compress or distill web content or documents before passing them to an LLM, especially in cost-sensitive RAG or multi-agent pipelines where token budget is a constraint. It is particularly useful when you need a measurable compression ratio (roi_proof) and are operating in a B2A/A2A context with x402/USDC micropayment support on Base.

## Known failure modes

- Missing or invalid 'url' query parameter returns an error or empty data
- Invalid HTTP method (not GET or POST) rejected by schema
- Unreachable or malformed target URL causes fetch failure
- Payment not settled in USDC on Base leads to 402 response blocking access
- Rate limiting or quota exhaustion if too many calls are made rapidly

## 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/distilled content, a 'status' field ('ok' on success), and a 'roi_proof' object that includes a 'compression_ratio_pct' value (e.g. 91.4%) showing how much the content was reduced.
