# CIEL M2M API – RAG Extreme

> CIEL M2M API – RAG Extreme is a paid API for AI agents from 169.58.38.67.sslip.io, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-18).

Runs a retrieval-augmented generation (RAG) query against an extreme-scale knowledge index, returning synthesized answers grounded in retrieved documents.

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 ciel-m2m-api-rag-extreme-29d28b51 -d '<json body>'
```

Example prompt: Use the CIEL RAG Extreme endpoint to answer this question: 'What are the main regulatory risks for crypto exchanges operating in the EU in 2024?' — search the knowledge base and give me a synthesized, grounded answer.

## When to prefer this

Choose this endpoint when you need AI-synthesized answers grounded in a retrieved document corpus rather than a purely generative response — especially for knowledge-intensive questions in crypto, compliance, or technical domains where hallucination risk must be reduced by retrieval grounding. Prefer it over plain LLM calls when factual accuracy and document support matter.

## Known failure modes

- Vague or missing query string returns a generic or empty result
- Malformed properties object causes a 400-level error
- Knowledge base does not contain relevant documents, returning low-confidence or empty synthesis
- Payment failure (insufficient USDC balance) results in 402 Payment Required
- Server-side timeout on large retrieval tasks may return a 503 or partial result

## How this service works

50+ micro-services for AI agents: data parsing, crypto analytics, security scanning, code tools, and more. Pay per call via x402 (USDC on Base) or RapidAPI subscription.

## Output

A JSON object containing a 'result' field with the synthesized answer or retrieved data generated by the RAG pipeline, grounded in documents from the knowledge index.
