# AgentDiet Grounded Citations

> AgentDiet Grounded Citations 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).

Retrieves grounded, compressed citations from a RAG-distilled context window, reducing token usage by up to 91% while preserving semantic fidelity.

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-grounded-citations-bb6b5985
```

Example prompt: Search for grounded citations about 'transformer attention mechanisms' using AgentDiet's RAG distiller — I want the compressed, token-efficient version with a compression proof showing how much I saved.

## When to prefer this

Choose this endpoint when your AI agent needs to retrieve cited, RAG-grounded information while aggressively minimizing token usage — especially in high-frequency pipelines where context window costs are significant. It is uniquely suited for agents operating under strict token budgets that still require sourced, verifiable answers rather than raw retrieved chunks. Prefer it over generic RAG retrieval when you need an auditable compression ratio (roi_proof) alongside the result.

## Known failure modes

- Missing required 'input' object returns 400 validation error
- Invalid HTTP method enum value (not GET or POST) causes schema rejection
- Empty or missing 'query' param returns empty data with no citations
- Payment not settled in USDC on Base results in 402 Payment Required
- Downstream RAG pipeline unavailability returns 503 or error 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 compressed, grounded citation results, a 'status' field confirming success, and an 'roi_proof' object showing the compression_ratio_pct (e.g. 91.4%) — demonstrating how much of the original context was eliminated while preserving semantic grounding.
