Feed Creation

Anyone can create a data feed on Molpha by connecting an API endpoint to the protocol. This guide walks you through the process.

​
Prerequisites

Before creating a feed, you’ll need:
  • API Endpoint — A publicly accessible API or protected API with credentials
  • JSONPath Selector — Knowledge of how to extract the value from the API response
  • Solana Wallet — With USDC for creation fees
  • Feed Configuration — Decide on update frequency and subscription duration

​
Creating a Feed

​
Step 1: Prepare Your API

Your API should return data in a consistent format. For example: 
{
  "bitcoin": {
    "usd": 45000.50
  },
  "ethereum": {
    "usd": 2800.75
  }
}

​
Step 2: Define Your Feed Specification

A feed specification includes:
FieldDescriptionExample
sourceAPI endpoint URLhttps://api.example.com/v1/price
selectorJSONPath to extract value$.bitcoin.usd
frequencyUpdate interval (seconds)60
signatures requiredMin number of node signatures needed to update the feed3

​
Step 3: Submit via Dashboard

  1. Visit the Molpha Dashboard
  2. Click “Create Feed”
  3. Fill in your feed specification
  4. Choose subscription duration (30-365 days)
  5. Pay creation fee in USDC

​
Step 4: Verification

After submission:
  1. Verifier nodes start fetching from your API
  2. Nodes validate and sign results
  3. Once quorum is reached, feed becomes active
  4. Updates are published according to your specified frequency

​
Feed Types

​
Public API Feeds

Feeds created for public use, sponsored feeds
  • Immutable -> once created configuration cannot be changed
  • Explorable though feed limits
  • Anyone can consume data onchain
  • There can be a consumer price set by the feed creator or they

​
Personal API Feeds

Feeds created for personal use only
  • Owner can update the configuration anytime
  • not explorable
  • owner can set the consumers

​
Feed Management

​
Updating Feed Configuration

You can update (Personal feeds only):
  • Update frequency
  • Signatures threshold
  • Subscription extension

​
Feed Lifecycle

  1. Draft — Created but not yet active
  2. Active — Receiving updates from verifiers
  3. Archived — Subscription expired, no longer updating
