# IMPERIUM WORKFLOWS Multi-Agent A2A DAG Pipeline Studio

> IMPERIUM WORKFLOWS Multi-Agent A2A DAG Pipeline Studio is a paid API for AI agents from workflows.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Orchestrates a 3-node multi-agent DAG pipeline chaining security audits, DeFi/on-chain risk checks, B2B OSINT, and RAG distillation in a single call.

## Facts

- Endpoint: GET https://workflows.agentdiet.dev/v1/alpha-stream?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-22
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/imperium-workflows-multi-agent-a2a-dag-pipeline-studio-6c04d4c4
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_QPjR-2Ki6JnDq6DqQvvAV

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 imperium-workflows-multi-agent-a2a-dag-pipeline-studio-6c04d4c4
```

Example prompt: Run a full multi-agent pipeline on https://example-protocol.io — chain the security audit, DeFi on-chain risk checks, and B2B OSINT recon, then distill everything into a compact summary using a GET request.

## When to prefer this

Choose this endpoint when you need a single-call orchestration that combines security auditing, DeFi/on-chain risk analysis, B2B OSINT, and RAG distillation rather than calling separate specialized endpoints. Ideal when you want token-compressed, multi-signal output from a 3-node DAG pipeline in one round trip.

## Known failure modes

- Missing required 'input' object with 'type' and 'method' fields returns validation error
- Invalid or unreachable target URL causes pipeline node failures with partial results
- Payment not completed via x402 protocol returns 402 Payment Required
- Target returns non-standard responses that break individual DAG node parsers
- Timeout on slow or rate-limited targets may produce incomplete pipeline output

## How this service works

Single-call 3-node multi-agent DAG workflow orchestrator chaining security audits, DeFi/on-chain risk checks, B2B OSINT, and RAG distillation over MCP and A2A.

## Output

Returns a JSON object with status 'ok', aggregated data from the 3-node DAG pipeline (security audit, DeFi/on-chain risk, OSINT, and RAG distillation results), and an roi_proof object showing compression ratio (e.g. 91.4%).
