Delx Data Classification
x402
Delx Data Classification is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Classifies a list of field names to identify which likely contain sensitive data, without inspecting actual values, returning deterministic machine-readable JSON.

How this service works
Classify a field-name inventory for likely sensitive data without inspecting values. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for aut…
Output
Returns a deterministic JSON object mapping each input field name to a classification indicating its likely sensitivity category (e.g. PII, financial, credential, non-sensitive), enabling the caller to make downstream data, policy, or security decisions without the service ever seeing actual data values.
Example use cases
PII preflight before data pipeline
“Before we push this dataset downstream, classify these field names for me — user_id, full_name, date_of_birth, email, postal_code, purchase_amount, session_token — so I know which ones are likely sensitive and need masking.”
Schema audit for GDPR compliance
“I need to audit our CRM schema for GDPR compliance. Can you classify these field names and tell me which ones likely contain personal data: customer_email, order_id, shipping_address, phone_number, loyalty_points, device_fingerprint, referral_code?”
Data integration security check
“We're about to integrate a third-party API and I want to flag any sensitive fields before we store anything. Please classify these field names: access_token, user_handle, credit_card_last4, transaction_id, geo_lat, geo_lon, consent_flag, internal_notes.”

Endpoint
POSThttps://api.delx.ai/api/v1/x402/data-classificationWhen to prefer
Choose this endpoint when you need a fast, stateless, privacy-safe preflight classification of field names — without sending actual data values to any external service. Ideal for enterprise agent workflows that need deterministic, machine-readable sensitivity labels before committing to data processing, policy enforcement, or integration decisions. Prefer it over general-purpose LLM classification when you need consistent, reproducible JSON output at low cost and zero data retention.
Side effects
- Empty or missing fields array returns an error or empty classification result
- Malformed input schema causes a 400 bad request
- Very large field inventories may exceed input limits
- Non-descriptive or ambiguous field names (e.g. 'col1', 'x') may yield low-confidence or generic classifications
- Payment failure via x402 returns 402 status blocking execution
