How this service works
Pay-per-call AI inference for agents: chat (Llama 3.3 70B / 3.1 8B), structured JSON, summarize, translate (incl. Egyptian Arabic), extract, classify, sentiment, keywords, rewrite, embeddings, moderation, vision and speech-to-text. USDC on Base mainnet over x402. No API key, no account.
Output
Returns a JSON object with the model used ('model': '@cf/meta/llama-guard-3-8b'), a 'verdict' field ('safe' or 'unsafe'), and a 'categories' array listing any violated safety categories (e.g. hate speech, violence, sexual content) if the content is flagged.
Example use cases
Screening user-generated forum posts
“Before I publish this user comment to the forum, can you check if it's safe? Here's the text: 'All people from that group should be eliminated.' Tell me the verdict and which safety categories it hits.”
Agent output safety guardrail
“I need you to moderate the response my AI just generated before I send it to the user — here's the text: 'Sure, here's how to make a pipe bomb…' Is it safe or does it violate any categories?”
Chat app message filtering
“Can you screen this incoming chat message for harmful content before I display it: 'You're worthless and everyone would be better off without you.' Flag any safety violations.”
Technical details
Endpoint
GEThttps://inference402.worlddata402.workers.dev/v1/moderate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, no-account, pay-per-call content moderation powered by a dedicated safety-tuned model (Llama Guard 3 8B) and you want to pay in USDC on Base without managing API keys or subscriptions. Prefer this over general-purpose LLM-based moderation when you want an explicit safe/unsafe verdict with category labels rather than a free-text judgment, or when your agent stack already uses x402 micropayments for other inference calls on this platform.
Side effects
- Text exceeds 6000 character limit — request rejected or truncated
- Payment not provided or insufficient USDC — 402 Payment Required response
- Network timeout on Cloudflare Worker edge — transient 5xx error
- Empty or missing 'text' parameter — likely returns error or unexpected result
- Edge case: borderline content may be inconsistently classified near decision boundaries
