Technical details
Endpoint
POSThttps://tempost.vercel.app/api/proofread?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call AI proofreading pass on a piece of text without committing to a full SaaS subscription. It is well-suited for agents that handle writing tasks episodically rather than at high volume, and when you want grammar, spelling, and punctuation correction in a single atomic call rather than assembling a pipeline of NLP tools.
Side effects
- Empty or missing 'text' field returns a 400 validation error
- Extremely long text inputs may time out or be truncated
- Non-text or binary input will fail schema validation
- Payment failure via x402 protocol prevents call execution
- Service unavailability on vercel.app infrastructure returns 500
