Understanding APIs: What They Are and How They Work


In the digital age, applications constantly interact with each other—whether it's your weather app pulling data from a meteorological server, or a crypto portfolio tracker fetching blockchain prices. The hidden force behind most of these interactions? APIs.
This blog post explores what an API is, how it works, and why APIs are so critical to modern software, including use in crypto and blockchain technologies.
What Is an API?
API stands for Application Programming Interface. It acts as a bridge that enables two separate software systems to communicate and share data. Much like a waiter taking your order and delivering food between you and the kitchen, an API relays requests and returns the appropriate responses.
Developers use APIs to simplify the building of software applications. Rather than writing code from scratch, APIs allow developers to pull in data, execute tasks, or access services provided by another app or platform.
How Does an API Work?
APIs operate through a series of requests and responses. The client (usually the application or user interface) sends a request to the server (which hosts the API). The API then handles this request, processes it based on pre-defined rules, and returns a response.
Here’s a simplified breakdown of the process:
Â
Â
Â
Most modern APIs are RESTful (Representational State Transfer) and operate via HTTP protocols. These APIs are platform-agnostic and highly scalable, making them suitable for both web and mobile applications.
Why APIs Matter in Crypto
APIs are fundamental to the crypto ecosystem because they allow developers to:

Types of APIs
APIs vary based on their purpose and accessibility. It's important to understand the distinctions when designing or integrating them.
Â
Â
Â
Â
In the crypto world, partner APIs are often provided by exchanges, while open APIs are commonly seen on market data aggregator platforms.
API Security and Governance
Given that APIs provide entry points into systems, security is a top priority. Common best practices include:
Â
Â
Â
Â
Enterprises also use API gateways and management layers to track usage, apply governance policies, and scale efficiently.
Real-World API Use Cases in Crypto
The crypto industry is teeming with API-driven applications. Here are a few impactful examples:
Â
Â
Â
Â
Whether for DeFi apps, on-chain research, or Web3 gaming—APIs provide the infrastructure for scaling innovation.
FAQs
What is a REST API?
A REST API (Representational State Transfer) is an architectural style that uses HTTP methods (GET, POST, PUT, DELETE) to facilitate communication between systems. It's known for being lightweight, stateless, and scalable.
How do crypto trading bots use APIs?
Trading bots use API integrations to access live market data, monitor trade signals, and execute trades automatically on exchanges based on pre-programmed logic.
Are APIs secure?
APIs can be secure if built with strong authentication, encryption, and rate limiting. However, poor implementation or public exposure without proper security layers can introduce vulnerabilities.
Can I build a crypto app using public APIs?
Yes. Many platforms like Token Metrics API offer public APIs to developers. These allow you to access real-time data and integrate core functionalities into your app.
What format do APIs return data in?
Most modern APIs return data in JSON format due to its readability and ease of use. Some also offer XML or CSV for legacy systems.

Best Lending/Borrowing Protocols (2025)
Why Lending/Borrowing Protocols Matter in September 2025
DeFi lending/borrowing protocols let you supply crypto to earn yield or post collateral to borrow assets without an intermediary. That’s the short answer. In 2025, these platforms matter because market cycles are faster, stablecoin yields are competitive with TradFi, and new risk-isolation designs have reduced contagion across assets. If you’re researching the best lending/borrowing protocols for diversified yield or flexible liquidity, this guide is for you—whether you’re a first-time lender, an active degen rotating between chains, or an institution exploring programmatic treasury management. We highlight security posture, liquidity depth, supported assets, fees, and UX. We also note regional considerations where relevant and link only to official sources.
How We Picked (Methodology & Scoring)
- Liquidity (30%): Depth/fragmentation across pools and chains, plus borrow/supply utilization.
- Security (25%): Audits, bug bounties, incident history, governance safeguards, and transparency.
- Coverage (15%): Asset breadth, multi-chain reach, stablecoin support.
- Costs (15%): Rate models, protocol/reserve fees, gas/bridge costs.
- UX (10%): Clarity of risk, market pages, docs, and integrations.
- Support (5%): Docs, dev portals, community response.
We relied on official product/docs and security pages; third-party market datasets (e.g., CCData/Kaiko/CoinGecko) were used only for cross-checks. Last updated September 2025.

FAQs
What is a DeFi lending/borrowing protocol?
A smart-contract system that lets users supply assets to earn interest or post collateral to borrow other assets, typically overcollateralized with algorithmic rates.
How do variable and stable borrow rates differ?
Variable rates change with utilization; stable/“fixed” rates are more predictable but can reprice under specific conditions. Always check the protocol’s docs.
Are isolated markets safer than shared pools?
They can reduce cross-asset contagion by containing risk to one market, but you still face collateral, oracle, and liquidation risks.
Which chains are best for low-fee lending?
Solana and several L2s (e.g., Arbitrum, Optimism, Base) offer lower fees than mainnet. Choose based on assets, liquidity, and tooling.
How much collateral should I post?
Many borrowers keep a conservative buffer (e.g., target health factor well above minimum), especially in volatile markets; tailor to your risk tolerance.
Can institutions use these protocols?
Yes—many funds and DAOs integrate with major money markets, often via smart-contract wallets and custom monitors.

FAQs
What’s the difference between KYC and KYT (Know Your Transaction)?
KYC verifies an individual or entity at onboarding and during refresh cycles. KYT/transaction monitoring analyzes wallets and transfers in real time (or post-event) to identify suspicious activity, sanctions exposure, and patterns of illicit finance. TRM Labs
Do I need a Travel Rule solution if I only serve retail in one country?
Possibly. Many jurisdictions apply the Travel Rule above certain thresholds and when sending to other VASPs, even domestically. If you interoperate with global exchanges or custodians, you’ll likely need it. Notabene
How do vendors differ on sanctions coverage?
Screening providers update against official lists and, in some cases, extend coverage using intelligence on known threat actors’ wallets. Look for rapid refresh cycles and retroactive screening. TRM Labs
Can I mix-and-match KYC and blockchain analytics vendors?
Yes. Many teams use a KYC/AML screening vendor plus a blockchain analytics platform; some suites offer both, but best-of-breed mixes are common.
What’s a good starting stack for a new exchange?
A KYC/KYB vendor (Jumio or Sumsub), a sanctions/PEP screening engine (ComplyAdvantage or your KYC vendor’s module), a blockchain analytics platform (Chainalysis/TRM/Elliptic), and a Travel Rule tool (Notabene or Veriscope).

How to Choose the Right Law Firm (Checklist)
- Jurisdictions you operate in (US/EU/APAC) and regulators you’ll face.
- Scope: corporate, regulatory, enforcement, litigation, restructuring—do they cover your stack?
- Security & compliance posture: AML/sanctions, custody rules, broker-dealer/adviser obligations.
- Fees: insist on scoping, budgets, and milestones; ask about blended rates or fixed-fee modules.
- Team: named partners + day-to-day associates; response times and communication norms.
- Tooling: client hubs/trackers and policy updates.
- Red flags: vague scope, no cross-border coordination, or “we’ve never done X in Y jurisdiction.”

Security & Compliance Tips
- Enforce strong 2FA and role-based access on exchange/broker accounts counsel touches.
- Set custody architecture and segregation early (on/off-exchange, MPC/HSM, signers).
- Complete KYC/AML and travel rule readiness; map licensure (e.g., MTL, MiCA).
- Use written RFQs/SOWs; document advice paths for auditability.
- Maintain wallet hygiene: least-privilege, whitelists, and incident playbooks.

Beginner Mistakes to Avoid

- Treating enforcement as PR—engage litigation/ex-government experience early.
- Launching tokens without jurisdictional analysis and disclosures.
- No budget guardrails: failing to phase work or set milestones.
FAQs
What does a crypto law firm actually do?
They advise on token and product structuring, licensing (e.g., money transmission, MiCA), securities/commodities issues, AML/sanctions, and handle investigations, litigation, deals, and restructurings. Many also publish policy trackers and hubs to keep clients current. Davis Polk+2Perkins Coie+2
How much do top crypto law firms cost?
Rates vary by market and complexity. Expect premium pricing for multi-jurisdictional or contested matters. Ask for detailed scopes, blended rates, and fixed-fee modules for licensing or audits.
Do I need a U.S. firm if I’m launching in the EU under MiCA?
