Introduction

Linkforge is a cryptocurrency data platform and out API provides developers with
reliable access to both market and on-chain insights. The API is designed for builders
who need accurate, real-time, and historical crypto information to power their
applications, trading systems, research tools, and analytics dashboards.

With Linkforge, you can easily fetch core metrics such as prices, market activity, liquidity
trends, and network indicators. The credit-based model allows you to pay only for the
data you use, offering flexibility for everything from small projects to enterprise
integrations.

Our goal is to make crypto data accessible, transparent, and simple to integrate.
Whether you are creating a trading bot, monitoring blockchain activity, or developing
financial dashboards, Linkforge provides a single gateway to the essential information
you need.

Getting Started

Getting started with Linkforge API takes just a few steps. This section will guide you
from creating an account to making your first successful API call.

1. Register an Account

Create your account on linkforge.app.
During registration, you provide:

Username
Email
Country
Password

After completing registration, you will automatically receive two keys:

public_key – used to publicly identify your application (safe to use in client-side
code)
api_key – private authentication key used to authorize all requests (keep this
secret)

Both keys are available in your dashboard.

2. Purchase Credits with Bitcoin

The Linkforge API uses a credit-based system.

Credits are the only way to access data through the API.
You can purchase credits exclusively with BTC.
Once your payment is confirmed on the blockchain, credits are instantly added to
your account balance.

3. Make Your First API Call

With your keys and credits ready, you can now make your first API request.
All API endpoints are hosted on the API subdomain:
https://api.linkforge.app/api/public/v1/bitcoin

Example: Get Bitcoin Price

				
					curl -H "x-api-key:
06768b4668df3f1e85b9a77094184c1356e87f6a58a0267d5a16f71c18a25060" \

"https://api.linkforge.app/api/public/v1/bitcoin/price?public_key=9080c7c4b3d8bc060904
68d95bab16205a45ad342c”

4. Key Rules

Always send your api_key in the request header (x-api-key).

You can include your public_key in the query string or in the header (x-publickey).
Never expose your api_key in client-side code or URLs.

Authentication & Keys

Every request to Linkforge API requires authentication using your API credentials.
When you register on linkforge.app, two keys are automatically generated for you:

public_key
- Public identifier for your application
- Safe to share in client-side integrations
- Can be sent either as a query parameter (public_key) or in a header (xpublic-key)
api_key
- Private secret used to authorize your requests
- Must always be kept secure and never exposed in client-side code or
  URLs
- Must be sent in the request header as x-api-key

Sending Credentials

Option 1: Public Key in Query String (Recommended for most cases)

				
					curl -H "x-api-key: YOUR_API_KEY" \
"https://api.linkforge.app/api/public/v1/bitcoin/price?public_key=YOUR_PUBLIC_KEY"

Option 2: Both Keys in Headers

				
					curl -H "x-api-key: YOUR_API_KEY" \
 -H "x-public-key: YOUR_PUBLIC_KEY" \
"https://api.linkforge.app/api/public/v1/bitcoin/price"

Credits Purchase

Access to the Linkforge API is based on a credit system. Each API call consumes
credits from your balance. In order to continue using the API, you need to purchase
additional credits.

Payment Method

Credits can be purchased exclusively with Bitcoin (BTC).
At the moment, no other cryptocurrencies or fiat payment options are supported.

Payment Method

In your Linkforge dashboard, create a new credit purchase order.
You will receive a BTC address and the exact amount to send.
Once you send the payment, the transaction will be monitored on the Bitcoin
blockchain.
Payments are verified once every 24 hours.
After verification, credits are added to your account balance.

Credits Usage

Every request to the Linkforge API consumes credits from your balance. This ensures a
simple and predictable pay-as-you-go model without monthly subscriptions.

How Credits Are Consumed

Each API request deducts 0.01 EUR from your balance (default rate, unless
otherwise specified).
The deduction happens immediately after a successful request.
If your balance is insufficient, the request will be rejected with an error.

Example Deduction Flow

1. User balance before request: 10.00 EUR credits
2. API call to /bitcoin/price → consumes 0.01 EUR credits
3. New balance after request: 9.99 EUR credits

What Happens When Balance Reaches Zero?

Requests with insufficient credits will return:

				
					
{
 "error": "Insufficient credit"
}

HTTP status: 402 Payment Required
To continue using the API, you must purchase additional credits.
