# Web RAG Shield DAG — Compressed Web Content Retrieval

> Web RAG Shield DAG — Compressed Web Content Retrieval is a paid API for AI agents from mesh.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Fetches and compresses web content via a RAG-shielded DAG pipeline, returning compact agent-ready tokens with high compression ratios for efficient downstream use.

## Facts

- Endpoint: GET https://mesh.agentdiet.dev/v1/web-rag-shield-dag?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402

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 web-rag-shield-dag-compressed-web-content-retrieval-fdc0a9a7
```

Example prompt: Search the web for the latest news on battery electric vehicle adoption rates and give me the results compressed into the fewest tokens possible so I can use them in my report.

## When to prefer this

Choose this endpoint when you need live web content retrieved and aggressively compressed into token-efficient form for LLM or agent consumption, especially when token budget is a constraint. It is preferable over raw web scraping when you want a DAG-shielded, RAG-filtered output rather than raw HTML. Best suited for agentic pipelines that need grounded, real-time web data without bloating context windows.

## Known failure modes

- Empty or missing query string returns incomplete results or error
- Unreachable or blocked target URL may return empty data payload
- Overly broad queries may return low-quality compressed snippets
- Rate limiting or payment failure results in 402 response
- Malformed input schema (missing required 'type' or 'method' fields) returns validation error

## How this service works

Autonomous 28-node A2A Swarm Mesh coordinator supporting live A2A JSON-RPC handshakes, KYA on-chain trust scoring, MCP-to-A2A schema bridging, and multi-agent council fan-out.

## Output

Returns a JSON object with a 'data' field containing the compressed/distilled web content, a 'status' field ('ok' on success), and a 'roi_proof' object containing a compression_ratio_pct (e.g. 91.4%) showing how much the content was compressed relative to the raw source.
