# AgentDiet Prompt Guard Alpha Stream

> AgentDiet Prompt Guard Alpha Stream is a paid API for AI agents from prompt-guard.agentdiet.dev, paid per call via x402 or MPP, $0.03/call, status unknown (last checked 2026-10-20).

Streams distilled intelligence from a target URL or query through a multi-app B2A hub covering web distillation, on-chain risk, DEX token intelligence, lead enrichment, domain OSINT, email verification, SEC filings, GitHub audits, and prompt firewall analysis.

## Facts

- Endpoint: GET https://prompt-guard.agentdiet.dev/v1/alpha-stream?utm_source=zero.xyz
- Price: $0.03/call
- Payment: x402, MPP
- Status: unknown
- Last checked: 2026-10-20
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/agentdiet-prompt-guard-alpha-stream-b51f7abb
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_zN6vj2-TzzidurRQVvjyW

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-prompt-guard-alpha-stream-b51f7abb
```

Example prompt: Distill the key intelligence from https://example.com using AgentDiet's alpha stream — I want the compressed structured output with ROI proof, fetched via GET.

## When to prefer this

Choose this endpoint when you need a single agent-native API that bundles web distillation, crypto/on-chain risk, DEX intelligence, domain OSINT, B2B lead enrichment, email verification, SEC filings, GitHub audits, and prompt firewall into one call. It is ideal for autonomous agents that need compressed, high-signal intelligence from multiple domains without integrating a dozen separate APIs, and when paying per-call via x402/USDC micropayments is acceptable.

## Known failure modes

- Missing or invalid `target` query parameter returns an error or empty data payload
- Unsupported HTTP method in the `method` field returns a validation error
- Target URL is unreachable or blocked, resulting in a failed distillation response
- Payment not completed (HTTP 402) blocks access until x402/USDC payment is settled
- Rate limiting or quota exhaustion returns a service unavailable error
- Malformed input schema causes a 400 bad request

## How this service works

15-App Autonomous Business-to-Agent (B2A) API Hub & MCP Suite. Supports Web Distillation, On-Chain Risk, DEX Token Intelligence, B2B Lead Enrichment, Domain OSINT, Email Verification, SEC Filings, GitHub Audits, Prompt Firewall, and native HTTP 402 (x402 Base USDC).

## Output

Returns a JSON object with a `status` field ('ok'), a `data` object containing the distilled or analyzed output from the requested capability (web distillation, OSINT, risk signals, etc.), and a `roi_proof` object including a `compression_ratio_pct` value indicating how efficiently the content was distilled (e.g. 91.4% compression).
