Overview
Hash Generator works by applying cryptographic hash functions to input text and returning the resulting hash digests. Supports multiple algorithms simultaneously and provides hash length and format details.
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.
curl "https://api.apiverve.com/v1/hashgenerator?text=Hello%20World&algorithms=sha256%2Cmd5" \
-H "x-api-key: your_api_key_here"const res = await fetch('https://api.apiverve.com/v1/hashgenerator?text=Hello%20World&algorithms=sha256%2Cmd5', {
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/hashgenerator?text=Hello%20World&algorithms=sha256%2Cmd5",
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/hashgenerator?text=Hello%20World&algorithms=sha256%2Cmd5", 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.
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.
| Parameter | Type | Description |
|---|---|---|
textRequired | string | Text to hash |
algorithmsOptional | string | Comma-separated list of algorithms or 'all'allmd5sha1sha256sha384sha512blake2b512blake2s256default all |
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.

}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.
| Field | Type | Example | Description |
|---|---|---|---|
input_text | string | "Hello World" | The original text that was hashed |
input_length | number | 11 | Character count of the input text |
algorithms_used | array | [sha256, ...] | List of hash algorithms applied to input |
hashes | object | {...} | Object mapping algorithm names to their hash values |
sha256 | string | "a591a6d40bf420404a011733cfb7b190d62c65bf0bcda32b57b277d9ad9f146e" | |
md5 | string | "b10a8db164e0754105b7a99be72e3fe5" | |
hash_detailsPremium | array[2] | Array of detailed hash information per algorithm | |
algorithmPremium | string | "sha256" | Name of the hash algorithm used |
hashPremium | string | "a591a6d40bf420404a011733cfb7b190d62c65bf0bcda32b57b277d9ad9f146e" | Hash value in lowercase hexadecimal format |
lengthPremium | number | 64 | Byte length of the hash output |
uppercasePremium | string | "A591A6D40BF420404A011733CFB7B190D62C65BF0BCDA32B57B277D9AD9F146E" | Hash value converted to uppercase 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.
| Status | Meaning | What to do |
|---|---|---|
400 | Input was rejected | Read error; it names the parameter. |
401 | Key missing or invalid | Check the header name and the key value. |
403 | Key valid, but not permitted | A key restriction or IP allow-list; see key scoping. |
429 | Rate limited, or out of credits | Read error to tell them apart; see rate limits. |
