How this service works
Rule-based multi-label text classification over a fixed taxonomy (urgency, financial_promise, credential_request, crypto_mention, cta, legal_offer, medical_claim, seo_spam, url_shortener, press_release, question, has_contact). Deterministic - identical text always yields identical labels.
Output
Returns a set of matched label names from the fixed 12-label taxonomy (urgency, financial_promise, credential_request, crypto_mention, cta, legal_offer, medical_claim, seo_spam, url_shortener, press_release, question, has_contact) for labels whose rule weights meet or exceed the specified threshold. Response is deterministic — identical inputs always produce identical label sets.
Example use cases
Spam filter for user-generated content
“Run this forum post through the multi-label classifier with default threshold and tell me which labels fire — especially looking for seo_spam, url_shortener, and financial_promise: 'Earn $5000/week from home! Visit our link: tinyurl.com/money123 and get started today!'”
Phishing email triage pipeline
“Classify this inbound email text for credential_request, urgency, and cta labels using threshold 3 so only strong signals come through: 'Your account has been compromised. Verify your login immediately by entering your password at the link below.'”
Content compliance screening
“I need to screen this advertiser copy for medical_claim and legal_offer labels before we publish it — use threshold 1 to catch even weak signals: 'Our supplement cures chronic pain. Results guaranteed or your money back. Consult your attorney for terms.'”
Technical details
Endpoint
POSThttps://api.maximusmediahouse.com/v1/classify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, deterministic, rule-based multi-label classification over a fixed content-safety taxonomy — especially for spam, financial fraud, phishing, or compliance screening pipelines where reproducibility is required. Prefer this over LLM-based classifiers when you need zero variance across identical inputs, low latency, and predictable cost at $0.003 per call. Best suited for high-volume content moderation where the 12-label taxonomy covers your use case.
Side effects
- Text shorter than 1 character or longer than 100,000 characters returns a validation error
- Threshold value outside 0-4 range returns a schema validation error
- Empty or null text field causes a bad request response
- Non-string text input causes type validation failure
- Network timeout on very large payloads near the 100,000 character limit
