How this service works
Chat, embeddings, OCR, speech-to-text, image editing, image understanding (captioning/Q&A), text-to-speech, translation, writing tools, classification tools, developer tools, local utilities, format/checksum validators, encoding & crypto utilities, date/time calculators, geo/coordinate math, math & finance calculators, novelty tools, and business/social writing generators — 179 endpoints in all, across multiple specialized self-hosted models. Pay per call with crypto — no signup — or get an API key.
Output
Returns an urgency classification for the submitted text — likely a label (e.g. low, medium, high, critical) and possibly a confidence score or numeric urgency value, indicating how time-sensitive or critical the content is.
Example use cases
Support ticket triage automation
“Classify the urgency of this support ticket so I know whether to escalate it immediately: 'The payment gateway has been failing for all users for the past 30 minutes.'”
Email inbox prioritization
“How urgent is this email I just received? 'Hi, I was wondering if you had any updates on the proposal we discussed last month — no rush, just checking in.'”
Alert severity triage
“I need to know if this monitoring alert is urgent: 'Disk usage on server db-prod-01 is at 95% and climbing.' Tell me the urgency level so I can decide whether to wake someone up.”
Technical details
Endpoint
POSThttps://api.fastapi.online/urgency-classifyWhen to prefer
Choose this endpoint when you need a cheap, no-signup, pay-per-call urgency classification for individual text snippets — particularly useful for real-time triage of support tickets, alerts, emails, or messages. Prefer it over heavier NLP pipelines when you only need an urgency label and cost efficiency matters. Well-suited for agentic workflows that process high volumes of short-to-medium text items and need to route or prioritize them automatically.
