Delx Field Coverage
x402
Delx Field Coverage is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Measures per-field presence rates across a bounded array of JSON records, returning deterministic coverage statistics for each field.

How this service works
Measure per-field presence across bounded JSON records. 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 authorization and production con…
Output
Returns a deterministic machine-readable JSON object with per-field statistics across the input records, including presence counts, total records, and coverage percentages for each field observed in the dataset.
Example use cases
ETL preflight data quality audit
“Before we run the ETL pipeline, check field coverage on these 500 customer records and flag any fields that are present in fewer than 80% of the records.”
Policy decision data completeness check
“I need to verify that all required fields are populated across these policy application records before the underwriting engine processes them — can you measure per-field coverage and tell me what's missing?”
API integration schema validation
“We're about to ingest these vendor JSON payloads into our system — run a field coverage analysis so I know which fields are consistently populated and which are unreliable before we build mappings.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/field-coverageWhen to prefer
Use this endpoint when you need a fast, stateless, deterministic audit of field completeness across a bounded JSON dataset as a preflight step before downstream data, policy, or integration decisions. Prefer it over custom scripts when you need machine-readable coverage output without storing or transmitting data to a third-party analytics platform.
Side effects
- Empty records array returns zero coverage results or an error
- Deeply nested JSON fields may only be measured at top-level unless flattening is applied
- Malformed JSON records may cause parsing errors or be skipped
- Very large record arrays may hit size limits
- Payment failure via x402 prevents execution
