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 a structured list of detected PII entities found in the input text, including entity type (e.g. NAME, EMAIL, PHONE, SSN, ADDRESS, CREDIT_CARD) and the specific text spans or values identified, along with confidence scores where available.
Example use cases
Pre-storage compliance check
“Before I save this support ticket to the database, scan it for PII — I need to know if it contains any personal info like names, emails, or phone numbers: 'Hi, I'm Sarah Johnson, my order number is 8821 and you can reach me at sarah.j@gmail.com or 212-555-0198.'”
Audit log scrubbing pipeline
“Check this log entry for personally identifiable information so I can decide whether to redact it: 'User 4492 (David Lee, dlee@corp.com, DOB 1985-03-22) logged in from IP 192.168.1.42.'”
User-submitted form validation
“Before we process this form submission, detect any PII in the free-text comment field: 'My name is Maria Gonzalez, I live at 45 Oak Street, Springfield, and my credit card ending in 4291 was charged incorrectly.'”
Technical details
Endpoint
POSThttps://api.fastapi.online/pii-detectWhen to prefer
Choose this endpoint when you need a low-cost, no-signup, pay-per-call PII detection service with no data retention commitments implied by enterprise SaaS. Ideal for automated pipelines that need to screen arbitrary text for personal data before storage or transmission, especially when crypto micropayments via x402 are already integrated. Prefer it over cloud provider PII APIs (AWS Comprehend, GCP DLP) when avoiding account setup friction or when cost-per-call pricing at $0.0015 USDC is advantageous for low-volume or bursty workloads.
Side effects
- Text exceeds 8000 character limit — 422 validation error
- Empty or missing text field — 422 validation error
- Payment not provided or insufficient — 402 Payment Required
- Model inference timeout on very dense or complex text
- False negatives on obfuscated or non-standard PII formats
- False positives on random strings that resemble PII patterns
