Overview

Stock Market Open Times works by querying a large database of stock market open times to retrieve the open times for each day of the week. It returns the stock market open times in a structured format.

Endpoint

One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.

GEThttps://api.apiverve.com/v1/stockmarketopentimes
curl "https://api.apiverve.com/v1/stockmarketopentimes?exchange=NYSE" \
  -H "x-api-key: your_api_key_here"
const res = await fetch('https://api.apiverve.com/v1/stockmarketopentimes?exchange=NYSE', {
  headers: { 'x-api-key': 'your_api_key_here' },
});

if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);

const { data } = await res.json();
console.log(data);
import requests

res = requests.get(
    "https://api.apiverve.com/v1/stockmarketopentimes?exchange=NYSE",
    headers={"x-api-key": "your_api_key_here"},
    timeout=15,
)
res.raise_for_status()

print(res.json()["data"])
package main

import (
	"fmt"
	"io"
	"net/http"
)

func main() {
	req, _ := http.NewRequest("GET", "https://api.apiverve.com/v1/stockmarketopentimes?exchange=NYSE", nil)
	req.Header.Set("x-api-key", "your_api_key_here")

	res, err := http.DefaultClient.Do(req)
	if err != nil {
		panic(err)
	}
	defer res.Body.Close()

	out, _ := io.ReadAll(res.Body)
	fmt.Println(string(out))
}

Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.

Authentication

Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.

401 is the only auth verdict

A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.

Parameters

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them.

ParameterTypeDescription

Response

Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.

Sample response
{
  "status": "ok",
  "error": null,
  "data": {
    "timezone": "America/New_York",
    "exchange": "NYSE",
    "fullName": "New York Stock Exchange",
    "isOpen": false,
    "openingTime": "2025-12-16 09:30:00",
    "closingTime": "2025-12-16 16:00:00"
  }
}

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.

FieldTypeExampleDescription
timezonePremiumstring"America/New_York"Timezone of the stock exchange location
exchangestring"NYSE"Stock exchange code or identifier
fullNamestring"New York Stock Exchange"Complete official name of the stock exchange
isOpenbooleanfalseWhether the stock market is currently open
openingTimestring"2025-12-16 09:30:00"Market opening time in datetime format
closingTimestring"2025-12-16 16:00:00"Market closing time in datetime format

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.

StatusMeaningWhat to do
400Input was rejectedRead error; it names the parameter.
401Key missing or invalidCheck the header name and the key value.
403Key valid, but not permittedA key restriction or IP allow-list; see key scoping.
429Rate limited, or out of creditsRead error to tell them apart; see rate limits.
