# AgentDiet B2A Intelligence & Distillation Hub (x402 Broker)

> AgentDiet B2A Intelligence & Distillation Hub (x402 Broker) is a paid API for AI agents from prompt-guard.agentdiet.dev, paid per call via x402 or MPP, $0.01/call, status unknown (last checked 2026-10-20).

Provides a unified GET endpoint that routes queries through a multi-app intelligence suite covering web distillation, on-chain risk, DEX token data, B2B lead enrichment, domain OSINT, email verification, SEC filings, GitHub audits, and prompt firewall, paid via HTTP 402 USDC micropayments.

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-b2a-intelligence-distillation-hub-x402-broker-21bf8eb8
```

Example prompt: Can you distill this URL into a clean summary and also check if the associated domain has any OSINT red flags — I want the compressed intelligence version, not the full raw page?

## When to prefer this

Choose this endpoint when you need a single paid-per-call hub that covers multiple intelligence domains (web, crypto, B2B, OSINT, email, SEC, GitHub, AI safety) without managing separate API keys for each service. Ideal for autonomous agents that pay via USDC x402 micropayments and need compressed, actionable intelligence rather than raw data. Best when breadth across domains matters more than deep specialization in any single area.

## Known failure modes

- Missing or invalid `query` param returns empty or error data object
- Payment not processed via HTTP 402 results in 402 response blocking access
- Unsupported method value causes schema validation failure
- Ambiguous query type may route to wrong sub-app within the hub
- Rate limiting or USDC wallet balance exhaustion causes repeated 402 rejections
- External data sources (SEC, GitHub, on-chain nodes) may be temporarily unavailable causing partial results

## 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

A JSON object with a `data` field containing the intelligence result for the queried capability (e.g. distilled content, risk scores, token data, lead info), a `status` field ('ok' on success), and a `roi_proof` object showing compression_ratio_pct (e.g. 91.4%) indicating how much the content was condensed.
