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 audit results, and an roi_proof object that includes a compression_ratio_pct value (e.g. 91.4%) indicating how much the content was compressed relative to the source.
Example use cases
Pre-call agent safety check
“Before my agent calls https://partner-api.io/v1/offers, can you audit that URL with a GET to make sure there's no prompt injection or adversarial content hiding in the response?”
Distilling third-party web content
“Fetch and distill the content at https://news-site.com/article/crypto-report using a GET request — I want a compressed intelligence summary my agent can act on quickly.”
B2A compliance scan before integration
“I'm integrating a new B2B data feed at https://vendor.io/feed?type=leads — can you audit it via GET and tell me the compression ratio and whether it passes the prompt firewall?”
Technical details
Endpoint
GEThttps://prompt-guard.agentdiet.dev/v1/x402-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to safely audit or pre-screen a URL for prompt injection, adversarial content, or B2A compliance before consuming its output — especially when you also want a compressed, distilled intelligence payload rather than raw HTML. Prefer it over generic scrapers when agent safety and prompt firewall validation are the primary concern.
Side effects
- Invalid or unreachable URL returns an error status
- Missing required 'type' or 'method' fields causes a 400 validation error
- Payment not fulfilled via x402 returns HTTP 402 Payment Required
- URL points to a non-HTTP resource and is rejected
- Rate limiting or quota exceeded returns an error response
