$0.002 per call · failed calls are never charged · no account or API key needed

Up to 8,000 characters. Also available in the OpenAI moderation shape at /v1/moderations. Use to screen user messages, model outputs or content before an agent posts or acts on it.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/ai/moderation?text=How%20do%20I%20bake%20sourdough%20bread%20at%20home%3F"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/ai/moderation?text=How%20do%20I%20bake%20sourdough%20bread%20at%20home%3F&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.

Example result

{
  "flagged": false,
  "categories": [],
  "model": "@cf/meta/llama-guard-3-8b"
}
