# IMPERIUM WORKFLOWS Multi-Agent A2A DAG Pipeline Studio – Preflight Certify

> IMPERIUM WORKFLOWS Multi-Agent A2A DAG Pipeline Studio – Preflight Certify 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).

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

## Facts

- Endpoint: GET https://workflows.agentdiet.dev/v1/preflight/certify?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-preflight-3cca7d69
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ukyle1iUvWm15e9ItbB_-

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-preflight-3cca7d69
```

Example prompt: Run a full preflight certification on https://example.com using a GET request — I need the security audit, DeFi risk check, and OSINT findings all in one shot.

## When to prefer this

Choose this endpoint when you need a single-call, multi-dimensional certification of a URL combining security auditing, DeFi risk assessment, and OSINT intelligence — rather than calling three separate specialist APIs. It's ideal for AI agent onboarding workflows, pre-integration vetting, or trust-scoring third-party endpoints before routing live traffic through them.

## Known failure modes

- Target URL unreachable or returns non-200 — pipeline may return partial results or error status
- Invalid or missing 'input' object causes schema validation failure
- Target URL behind authentication wall prevents OSINT and security scan from completing
- DeFi/on-chain check may fail if the URL doesn't correspond to a blockchain-related resource
- Rate limiting or payment failure (x402) blocks the call entirely

## 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 a status field ('ok'), a data object containing aggregated findings from the 3-node pipeline (security audit results, DeFi/on-chain risk signals, and B2B OSINT data), and a roi_proof object showing a compression_ratio_pct indicating how much the RAG distillation compressed the raw data (e.g. 91.4%).
