JSON Timestamp Fields Check
x402
JSON Timestamp Fields Check is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Validates selected fields in a JSON object as integer epoch seconds, checking they fall within caller-supplied minimum and maximum bounds, and returns counts, normalized values, and a versioned result contract.

How this service works
JSON Timestamp Fields Check: JSON Timestamp Fields Check checks selected fields as integer epoch seconds within bounds from bounded caller-supplied values without an external provider. Call JSON Timestamp Fields Check before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Timestamp Fields Check as versioned deterministic…
Output
Returns a versioned deterministic result containing: validation finding (pass/fail per field), counts of valid and invalid fields, normalized epoch values for each checked field, and a versioned result contract describing the schema of the response.
Example use cases
Pre-flight timestamp check for downstream API
“Before I send this event payload to the analytics pipeline, can you verify that the 'event_time' and 'received_at' fields are valid epoch seconds between 1600000000 and 1800000000? Here's the object: {"event_id": "evt_001", "event_time": 1712300000, "received_at": 1712300500}.”
Batch plan timestamp bounds validation
“I'm about to hand this batch job plan to the scheduler — can you check that 'start_epoch' and 'end_epoch' are both valid integer epoch seconds and fall between 1700000000 and 1750000000? Here's the plan object: {"job_id": "job_42", "start_epoch": 1710000000, "end_epoch": 1745000000}.”
Detecting out-of-range timestamps in user data
“Can you check whether the 'registered_at' and 'last_login' fields in this user record are reasonable unix epoch seconds — they should be between 1000000000 and 1800000000? Object is: {"user_id": "u_99", "registered_at": 1650000000, "last_login": 9999999999}.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/json-timestamp-fields-checkWhen to prefer
Use this endpoint when you need a deterministic, bounded, in-memory check of integer epoch second timestamps across multiple fields of a JSON object before passing structured data to a downstream system with a strict contract. It is especially useful in agentic pipelines where you want a versioned, auditable validation result without retaining or externalizing the data. Prefer it over generic JSON schema validators when epoch-second bounds checking per named field is the specific requirement.
Side effects
- Field names in 'fields' array do not exist in the provided object — fields will be counted as invalid or missing
- Non-integer values in timestamp fields cause validation failures
- minimum_epoch greater than maximum_epoch causes undefined or error response
- Object exceeds maxProperties limit of 128 — request rejected
- Fields array exceeds maxItems limit of 256 — request rejected
- Network or payment failure returns HTTP 402 or connection error
