Overview

To use JSON to JSONP, you need an API key. You can get one by creating a free account and visiting your dashboard.

POST Endpoint

URL
https://api.apiverve.com/v1/jsontojsonp

Example

How to call the JSON to JSONP API in different programming languages.

cURL Request
curl -X POST \
  "https://api.apiverve.com/v1/jsontojsonp" \
  -H "X-API-Key: your_api_key_here" \
  -H "Content-Type: application/json" \
  -d '{
  "callback": "callbackFunction",
  "json": {
    "menu": {
      "id": "file",
      "value": "File",
      "popup": false
    }
  }
}'
JavaScript (Fetch API)
const response = await fetch('https://api.apiverve.com/v1/jsontojsonp', {
  method: 'POST',
  headers: {
    'X-API-Key': 'your_api_key_here',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    "callback": "callbackFunction",
    "json": {
        "menu": {
            "id": "file",
            "value": "File",
            "popup": false
        }
    }
})
});

const data = await response.json();
console.log(data);
Python (Requests)
import requests

headers = {
    'X-API-Key': 'your_api_key_here',
    'Content-Type': 'application/json'
}

payload = {
    "callback": "callbackFunction",
    "json": {
        "menu": {
            "id": "file",
            "value": "File",
            "popup": false
        }
    }
}

response = requests.post('https://api.apiverve.com/v1/jsontojsonp', headers=headers, json=payload)

data = response.json()
print(data)
Go (net/http)
package main

import (
    "fmt"
    "io"
    "net/http"
    "bytes"
    "encoding/json"
)

func main() {
    payload := map[string]interface{}{
        "callback": "callbackFunction",
        "json": "[object Object]"
    }

    jsonPayload, _ := json.Marshal(payload)
    req, _ := http.NewRequest("POST", "https://api.apiverve.com/v1/jsontojsonp", bytes.NewBuffer(jsonPayload))

    req.Header.Set("X-API-Key", "your_api_key_here")
    req.Header.Set("Content-Type", "application/json")

    client := &http.Client{}
    resp, err := client.Do(req)
    if err != nil {
        panic(err)
    }
    defer resp.Body.Close()

    body, _ := io.ReadAll(resp.Body)
    fmt.Println(string(body))
}
Example Response
{
  "status": "ok",
  "error": null,
  "data": {
    "callback": "callbackFunction",
    "jsonp": "callbackFunction({\"menu\":{\"id\":\"file\",\"value\":\"File\",\"popup\":false}});"
  }
}

Authentication

The JSON to JSONP API requires authentication via API key. Include your API key in the request header:

Required Header
X-API-Key: your_api_key_here

Other Response Formats

XML Response
200 OK
<?xml version="1.0" encoding="UTF-8"?>

keyvalue
callbackcallbackFunction
jsonpcallbackFunction({menu:{id:file,value:File,popup:false}});

Response Structure

All API responses follow a consistent structure with the following fields:

FieldTypeDescriptionExample
statusstringIndicates whether the request was successful ("ok") or failed ("error")ok
errorstring | nullContains error message if status is "error", otherwise nullnull
dataobject | nullContains the API response data if successful, otherwise null{...}

Response Data Fields

When the request is successful, the data object contains the following fields:

FieldTypeSample ValueDescription
callbackstring"callbackFunction"
-
jsonpstring"callbackFunction({"menu":{"id":"file","value":"File","popup":false}});"
-

Headers

Only X-API-Key is required. Optional headers include Accept for response format negotiation (JSON, XML, or YAML), User-Agent, and X-Request-ID for request tracing. See all request headers →

GraphQL AccessALPHA

Access JSON to JSONP through GraphQL to combine it with other API calls in a single request. Query only the json to jsonp data you need with precise field selection, and orchestrate complex data fetching workflows.

Test JSON to JSONP in the GraphQL Explorer to confirm availability and experiment with queries.

Credit Cost: Each API called in your GraphQL query consumes its standard credit cost.

GraphQL Endpoint
POST https://api.apiverve.com/v1/graphql
GraphQL Query Example
query {
  jsontojsonp(
    input: {
      callback: "callbackFunction"
      json: {"menu":{"id":"file","value":"File","popup":false}}
    }
  ) {
    callback
    jsonp
  }
}

Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.

CORS Support

The JSON to JSONP API accepts cross-origin requests from any origin, so it can be called directly from browser-based applications without a proxy. See CORS support →

Rate Limiting

JSON to JSONP requests are throttled per minute on the Free plan and unthrottled on paid plans. Exceeding the limit returns 429 Too Many Requests; rate-limit usage is reported in the X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset response headers. See per-plan limits and best practices →

Error Codes

The JSON to JSONP API uses standard HTTP status codes — 200 on success, 400 for invalid parameters, 401 for missing or invalid keys, 403 for insufficient credits, 429 for rate-limit exhaustion, and 500/503 for server-side issues. Each error response includes an X-Request-ID header you can quote when contacting support. See full error handling guide →

SDKs for JSON to JSONP

Frequently Asked Questions

How do I get an API key for JSON to JSONP?
Sign up for a free account at dashboard.apiverve.com. Your API key will be automatically generated and available in your dashboard. The same key works for JSON to JSONP and all other APIVerve APIs. The free plan includes 1,000 credits plus a 500 credit bonus.
How many credits does JSON to JSONP cost?

Each successful JSON to JSONP API call consumes credits based on plan tier. Check the pricing section above for the exact credit cost. Failed requests and errors don't consume credits, so you only pay for successful json to jsonp lookups.

Can I use JSON to JSONP in production?

The free plan is for testing and development only. For production use of JSON to JSONP, upgrade to a paid plan (Starter, Pro, or Mega) which includes commercial use rights, no attribution requirements, and guaranteed uptime SLAs. All paid plans are production-ready.

Can I use JSON to JSONP from a browser?
Yes! The JSON to JSONP API supports CORS with wildcard configuration, so you can call it directly from browser-based JavaScript without needing a proxy server. See the CORS section above for details.
What happens if I exceed my JSON to JSONP credit limit?

When you reach your monthly credit limit, JSON to JSONP API requests will return an error until you upgrade your plan or wait for the next billing cycle. You'll receive notifications at 80% and 95% usage to give you time to upgrade if needed.
