Crypto APIs Review: Unified Access to 30+ Blockchains & 100+ Exchanges

Discover how Crypto APIs simplifies blockchain development with unified REST and JSON-RPC access to 30+ networks and 100+ exchanges.

Crypto APIs has rapidly become a linchpin in blockchain development, offering a unified infrastructure layer that abstracts away the complexity of interacting with disparate networks and exchanges. Launched in 2018, the platform provides fast, reliable REST and JSON‑RPC APIs to access both real‑time and historical data across more than 30 blockchains and 100 exchanges, all through a single integration.

This convergence of services not only accelerates time‑to‑market for projects—from DeFi protocols to NFT marketplaces—but also significantly reduces ongoing maintenance overhead. By standardizing endpoints and data formats, Crypto APIs empowers developers and enterprises to focus on innovation rather than infrastructure, making it an indispensable tool in the Web3 toolkit.

Founding Vision and Early Momentum

Crypto APIs emerged from the founders’ firsthand experience with fragmented blockchain integrations at TokenGet. Co‑founders Nashwan Khatib (Co‑Founder & CEO) and Viktor Petrov (Co‑Founder & COO) recognized that the proliferation of chains and protocols created a “white spot” in developer tooling, where each new integration demanded bespoke code and constant upkeep.

In 2019, the startup secured a coveted spot in the Microsoft for Startups program, gaining $120,000 in Azure credits that fueled its global node network and Kubernetes‑based architecture. By 2021, Crypto APIs’ leadership and technology caught the eye of WonderFi, leading to an acquisition valued between $15 million and $25 million—underscoring the platform’s market leadership and strategic importance.

Leadership and Expert Team

Under Khatib’s product‑driven vision and Petrov’s operational rigor, Crypto APIs has assembled a leadership team with deep domain expertise. Ognian Marinov (CTO) spearheads the platform’s technical roadmap, ensuring low‑latency, high‑throughput performance, while Beduil Dauis (Chief Sales Officer) drives enterprise adoption across finance, gaming, and DeFi sectors.

Kristiyan Lozanov (COO) orchestrates global delivery, from onboarding workshops to 24/7 SLA support. Complementing the executive suite is a distributed team of 18 engineers and support specialists, all contributing to a culture of continuous improvement and rapid feature delivery. With over 1,800 X followers and active presence on LinkedIn, Discord, and Telegram, the team maintains an open dialogue with its community, fostering trust and collaboration.

Comprehensive Product Suite

Crypto APIs’ modular architecture is organized into three core domains—Blockchain APIs, Market Data APIs, and Exchange & Wallet Management APIs—encompassing more than 400 unified endpoints. Whether it’s Node as a Service for JSON‑RPC access, Address Data for balance and transaction history, or Market Data aggregating OHLCV and order book snapshots, each service is designed for plug‑and‑play integration.

The platform also offers Smart Contract Tools for ABI decoding and gas estimation, Blockchain Automations for automatic token forwarding, and Webhooks & Events to capture on‑chain triggers with sub‑100 ms latency. This breadth of functionality positions Crypto APIs as a one‑stop solution for any project requiring robust blockchain infrastructure.

Deep Dive: Core Offerings

The following are the core offerings of the platform:

• Node as a Service (NaaS): Provides shared or dedicated JSON‑RPC nodes across 30+ blockchains, eliminating node provisioning and maintenance headaches.

• Blockchain Data: Delivers real‑time and historical data for addresses, UTXOs, and blocks, with big‑data indexing to support complex queries without performance degradation.

• Market Data: Aggregates trading data from 100+ exchanges into a single RESTful API, offering OHLCV, tickers, and order book depth for quantitative and algorithmic strategies.

• Wallet as a Service (WaaS): Employs MPC‑based key management for secure HD wallet generation and transaction signing, backed by HSM integrations.

• Blockchain Events & Webhooks: Enables subscription to on‑chain events—such as mined transactions or token transfers—with guaranteed delivery and retry logic.

Scalable, High‑Performance Infrastructure

At its core, Crypto APIs leverages a microservices architecture orchestrated via Kubernetes, deployed across multi‑cloud providers (AWS, Azure, GCP) and regions (US, EU, Asia) for redundancy and geo‑proximity. The ISO/IEC 27001:2013 certification, validated by TÜV Rheinland, attests to the platform’s rigorous security controls and encryption standards. With an average response time of 25 ms and the ability to handle over 25,000 requests per second, the network of over 500 nodes ensures uninterrupted service even under peak loads.

Security and Compliance

Security is non‑negotiable for Crypto APIs. All API traffic is secured via TLS 1.2+, while data at rest is encrypted with AES‑256 and managed through HSMs. Regular third‑party penetration tests and vulnerability scans identify and remediate risks proactively. GDPR compliance and data residency controls ensure that customer data sovereignty requirements are met, making the platform suitable for regulated industries such as banking and insurance.

Developer Experience and Ecosystem

To streamline adoption, Crypto APIs provides an interactive Developers Portal featuring live API explorers, comprehensive OpenAPI specifications, and auto‑generated SDKs in JavaScript, Python, Java, .NET, PHP, Ruby, and Rust. Detailed tutorials cover common scenarios—wallet integration, portfolio tracking, NFT minting—and sample code snippets accelerate prototyping. Community channels on Discord and Telegram, combined with regular webinars and blog deep‑dives, foster peer support and knowledge sharing. The platform’s integration with Swagger, APIMatic, and Azure AutoRest further optimizes CI/CD workflows.

Real‑World Use Cases and Case Studies

Crypto APIs powers a diverse set of applications:
