How this service works
Machine-readable settlement service
Output
Returns a structured object containing moderation decisions such as policy violation flags, content categories triggered, safety classifications, and potentially confidence scores indicating the severity or certainty of any detected violations.
Example use cases
Screening user comments before publishing
“Before I publish this user review, run it through content moderation and tell me if it contains anything harmful or policy-violating: 'This product is garbage and the CEO should be fired into the sun.'”
Filtering chat messages for hate speech
“Check this chat message for hate speech or offensive content and flag it if it violates safety guidelines: 'Those people don't belong here and never will.'”
Automating submission moderation for a forum
“I'm getting flooded with forum submissions — can you moderate this post and classify whether it's safe to publish or needs human review? Here's the text: 'Click here for free crypto, no catch, just send your wallet address.'”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/mini/ai.moderate--content-moderationWhen to prefer
Choose this endpoint when you need a pay-per-call, no-subscription content moderation API that integrates with x402 micropayment rails. It's well-suited for agents that moderate sporadically or at variable volume without committing to a monthly plan. Prefer this over heavyweight moderation platforms when cost-per-call economics matter and you want machine-readable settlement baked in.
Side effects
- Missing or malformed 'input' field returns a validation error
- Ambiguous or empty content object may yield low-confidence or null classifications
- Payment failure (402) if USDC balance is insufficient — call is rejected before moderation runs
- Timeout or 5xx if the underlying AI moderation model is unavailable
- Overly broad input objects without clear text fields may produce generic or unreliable results
