Zero APIs Overview

Zero APIs are designed to deliver real-time blockchain data through REST endpoints, catering to diverse Web3 development needs. Whether for fundamental portfolio management—such as retrieving balances, transaction histories, and price data—or advanced DEX analytics, Zero APIs provide a comprehensive and scalable solution.

Being sharpened towards complementary solution for AI agents, Zero API gives unmatched data filtering and retrieval capabilities. For example, a simple and popular requirement is to know the history of the interaction of a wallet with blockchains. Traditionally, the endpoints offer less context and maximum of 20 results in response making AI Agents to wait and be stuck for several minutes to retrieve all the transactions. Zero API offers the bulk of the transaction history at the same amount of time as making one call.

We understand that certain AI-driven applications might require access to bigger historical datasets for large analytics requests, training models etc. Project Zero compliments Zero API with direct data sharing options balancing data access paths for best efficiency. See Data Products: Overview

To ensure fairness and scalability, Zero APIs include rate limits, authentication mechanisms, and usage tiers. Developers can integrate APIs seamlessly into their workflows, with tiered access enabling them to scale usage based on their specific requirements. Whether developers are prototyping or managing production-grade systems, Zero APIs offer the flexibility and performance needed to support a wide range of applications.

Powered by a cross-chain data lake and query engine with hybrid storage, Zero APIs offer unmatched scalability, reliability, and data maintainability for blockchain applications.

Endpoints

• /chains – Returns a list of blockchain networks supported by Zero API.
• /tokens – Provides an overview of token information, including deployments per chain, current prices, and metadata.
• /wallet/balances – Fetches current balances for native and ERC-20 tokens in a given wallet.
• /user/activities – Retrieves a history of a user's blockchain interactions, including transactions and ERC-20 transfers.

Authentication

Zero API uses a simple static API key authentication mechanism, allowing users to manage and control their API keys efficiently.

Rate Limiting

To ensure scalability and system performance, Zero API employs a floating rate limit strategy, dynamically adjusting limits based on system load and demand.

Overview

Zero APIs are designed to deliver real-time blockchain data through REST endpoints to accommodate diverse web3 apps development needs.

From fundamental portfolio management tasks such as retrieving balances, transaction histories, and price data to advanced DEX analytics, Zero APIs offer comprehensive solutions.

Zero API fueled by cross-chain data lake and query engine with hybrid storage to give unmatched scalability and data maintainability.

Endpoints

• chains

  List of chains support by Zero API

• tokens

  Endpoint aims to provide an overview of token info, such as deployments per chain, current price etc

• wallet/balances

  To provide current balances for native and erc20 tokens of the wallet

• user/activities

  To provide list of user's interaction with blockchain (transactions, erc20 transfers etc)

Authentication

Zero API applies straightforward authentication by static API keys, allowing users to control key lifecycle.

Rate limiting

We use floating rate limit to ensure scalability and guarantee performance of the system.
