Uniblock Presents Unified APIs to Midnight Builders

Uniblock demonstrated its unified API platform during a Midnight Build Club session, showing developers how to access blockchain services through a shared integration. Co-founder and CEO Kevin Callahan presented tools for retrieving wallet, token, and transaction data, alongside a routing system designed to handle disruptions at underlying providers. The presentation focused on infrastructure tasks that application teams would otherwise build and maintain themselves.

A Shared Interface for Blockchain Data

Uniblock sits between applications and blockchain service providers. Its Unified API standardizes responses from different sources, reducing the work required to combine their data inside an application. The platform also offers RPC access for communicating with blockchain nodes and direct access to provider functions outside the unified interface.

Official documentation describes coverage across more than 300 networks and 55 providers. Availability varies by service and blockchain. During the session, Callahan discussed sources including Alchemy, CoinGecko, CoinMarketCap, and Zerion, with categories covering market information, wallets, NFTs, and transactions.

A question about tracking NFT projects on Ethereum or Solana produced a practical example. Callahan explained that developers could retrieve collection information and associated wallet data through the platform. Documented functions include token balances, transfer histories, NFT metadata, and transaction details, supporting applications such as portfolio trackers and analytics tools.

The integration provides access to information and infrastructure services. Transferring assets between blockchains requires separate mechanisms.

Routing Around Provider Disruptions

As applications grow, teams often add backup providers and build systems to switch between them during interruptions. That creates ongoing work: monitoring availability, maintaining integrations, and managing separate service plans.

According to Callahan, Uniblock’s routing system considers response times, cost, data freshness, and correctness. Where providers support equivalent requests, it can select an alternative source. He described data sampling and provider monitoring as part of the process for limiting the impact of upstream problems on customer applications.

The billing model addresses another source of complexity. Separate subscriptions can leave unused credits with one provider while an application needs more capacity elsewhere. Uniblock consolidates consumption and gives teams access to selected services without separately purchasing a full plan from every source.

Callahan cited customer savings but distinguished widely available infrastructure from specialized APIs. Services offered by several providers create different pricing opportunities from products built around distinctive data. Under this arrangement, Uniblock manages routing and billing for the selected services, reducing the number of supplier relationships the application team handles directly.

Midnight Coverage and Build Club Access

During the session, Callahan described Midnight integration as work in progress. Uniblock’s current website now lists Midnight with a “Partial Coverage” label, without detailing a complete set of supported functions. The platform’s overall network and provider counts therefore describe its broader catalog, rather than the services available specifically for Midnight.

Callahan also offered access through Model Context Protocol, or MCP, for teams connecting AI tools to blockchain data. This was presented as an additional platform capability that participants could explore for their projects.

Build Club participants were offered coupons to try Uniblock, while organizers planned shared channels for questions and technical assistance. The documented onboarding process begins with creating a project and obtaining an API key, followed by selecting the required services.

The team’s offer extended to helping builders identify suitable data sources and integrate them into their applications. For participants developing products that need information from several networks, the session provided a route to test those connections with direct support from Uniblock’s engineers.
