Spectrum Marketplace: On-Chain APIs For Staking Rates, Token Prices And NFT Data

Spectrum Marketplace: One API For Staking Rates, Token Prices, NFT Data And Safe Wallets

Spectrum Marketplace is a storefront for plug and play APIs that read on chain contracts and return the results as plain JSON. It is live now inside the Spectrum dashboard, with nine contract APIs and a wallet monitoring service at launch, priced on usage with no contract.

What Is Spectrum Marketplace?

A catalogue of micro services running on Spectrum node infrastructure. Each one wraps a widely used on chain contract behind a standard REST API.

You call the API. Spectrum runs the nodes, the decoding, the caching and the upgrade handling underneath it. It sits alongside Nodes, APIs, Webhooks and the upgrades Calendar in the dashboard, so it uses the same authentication and the same billing as the rest of the platform.

What Problem Does It Solve?

Three costs that never appear in a sprint estimate.

Contract decoding. Every protocol stores its data differently. Finding the right method, handling the right decimals and testing against a live network before you trust it.

Repetition. Supporting five liquid staking tokens is five integrations, each with its own quirks and each able to break on its own.

Maintenance. A network upgrades, a binary changes, and middleware that worked for eight months quietly returns something different. You hear about it from a user rather than from your monitoring.

What Is Available At Launch?

Nine contract APIs plus a wallet monitoring service.

Which Liquid Staking Tokens Are Supported?

Five, read from the contracts themselves rather than a third party aggregator: stETH and wstETH issued by Lido, rETH by Rocket Pool, weETH by ether.fi, cbETH by Coinbase and sUSDe by Ethena.

One integration covers all five.

Which Chains Are Supported For Token Prices?

Six: Ethereum, Base, Arbitrum, Polygon, BNB Chain and Avalanche.

The request shape is identical on every network. You change the chain parameter and nothing else in your code.

How Does Pricing Work?

On consumption of the service. No long term contract, no seat count, no minimum commitment.

A prototype pays prototype money. Spend rises with usage rather than ahead of it, which matters when you are shipping a feature you are not yet sure your users want.

What Happens When A Chain Upgrades?

Spectrum absorbs it before it reaches you. Every Marketplace service runs on Spectrum node infrastructure, so upgrades are handled at the infrastructure layer and the endpoint you called last month behaves the same way this month.

Can I Try It Without Writing Code?

Yes. Every service page has a live request panel. Run a real request in the browser and see the exact response shape before committing anything to your codebase. The panel is read only.

How Do I List My Own Contract?

Open a ticket from the dashboard and the Spectrum team will help get it listed. The Marketplace works in both directions: distribution for services other teams need, on infrastructure you do not have to operate.

Frequently Asked Questions

How much does it cost?

It is priced on consumption. You pay for the requests you make, with no contract and no minimum.

Do I need to run a node?

No. Spectrum runs the node infrastructure behind every service.

Which staking protocols does it support?

It reads the contracts behind Lido, Rocket Pool, ether.fi, Coinbase cbETH and Ethena.

Can I monitor a wallet address for activity?

Yes. Wallet Tracker watches addresses across chains and notifies you over HTTPS, Slack or Telegram.

Is there an SDK?

Yes, a TypeScript SDK, alongside the REST API reference and full documentation.
