Unix Timestamp Converter API

About the Unix Timestamp Converter API

Unix Timestamp Converter works by converting Unix epoch timestamps to formatted dates or parsing date strings into Unix timestamps. Returns comprehensive date information including year, month, day, time components, and multiple standard formats.

What people use it for

API Development

Convert timestamps from databases and APIs to human-readable dates for display in applications

Log Analysis

Parse timestamps in log files and system events for debugging and monitoring

Data Migration

Convert date formats between different systems and databases during data transfer

Time Synchronization

Standardize time representations across distributed systems using epoch timestamps

Ways to call it

One endpoint, many ways in — REST with JSON, XML, YAML and CSV, plus GraphQL and an MCP interface for AI agents.

Request parameters — GET /v1/unixtimestamp

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them. Anything not listed here is dropped rather than passed through.

Required

Optional

curl "https://api.apiverve.com/v1/unixtimestamp?timestamp=1609459200&format=seconds" \
  -H "x-api-key: YOUR_API_KEY"

Authentication

Send your key in the x-api-key header. That is the only auth step — no token exchange, and no per-endpoint scope to configure.

Response — GET /v1/unixtimestamp

Every APIVerve endpoint returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape.

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Response headers

Every response carries your balance, so your own code always knows where it stands without polling anything. All four are exposed to browsers through CORS.

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change.

What a call costs — 2 credits per call

Credits are shared across every APIVerve API — one balance, one key, one bill. Failed requests never count against it, so a rejected input costs nothing.

Calls are what the credits buy at this API's rate — spend them here, on any of the other APIs, or across both. Nothing is reserved per endpoint.

Zero-code embed — one snippet, no backend

Drop an interactive Unix Timestamp Converter form onto any page. The widget calls the API for you, so no key ever appears in your markup and there is nothing to deploy.

Changelog — Unix Timestamp Converter API

Every change to this endpoint, newest first. Breaking changes ship as a new version and the previous one keeps serving — response fields are added, never removed or retyped in place, so an integration written against v1 keeps working.
