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).

Conclusion + Related Reads

Compliance isn’t one tool; it’s a stack. If you’re U.S.-regulated and high-volume, start with Chainalysis or TRM plus Jumio or Sumsub. If you’re EU-led, Scorechain can simplify audits.

APIs Explained: How They Power Software and Crypto

Token Metrics Team

MIN

APIs are the invisible connectors that let apps talk to each other. Whether you’re loading a weather widget, pulling crypto prices into a dashboard, or integrating an AI model, understanding how APIs work helps you design, evaluate, and secure systems that depend on reliable data.

What is an API?

An API—Application Programming Interface—is a clearly defined set of rules and contracts that lets one software program request services or data from another. At its core an API specifies how to format requests, what endpoints are available, what parameters are accepted, and how the provider will respond. Think of it as a menu at a restaurant: you pick dishes (requests), the kitchen prepares them (the service), and the waiter returns your order (the response) without exposing internal cooking processes.

APIs exist at many levels: operating system APIs expose filesystem and device operations, library APIs expose functions and classes, and web APIs expose remote services across networks. In modern web and mobile development, "API" often refers to HTTP-based interfaces that return structured data like JSON or XML.

How APIs Work: Requests, Responses, and Data Formats

Most web APIs operate on a request–response model. A client issues a request to a defined endpoint using a method (GET, POST, PUT, DELETE), optionally supplying parameters or a payload. The server processes the request and returns a response with a status code and body.

Key technical elements to understand:

  • Endpoints: URLs that map to resources or actions (e.g., /v1/prices).
  • HTTP Methods: Semantic actions (GET = read, POST = create, etc.).
  • Status Codes: 2xx successes, 4xx client errors, 5xx server errors.
  • Data Formats: JSON is ubiquitous for APIs due to its simplicity; XML and protobufs appear in legacy or high-performance systems.
  • Authentication & Authorization: API keys, OAuth tokens, JWTs, and mTLS govern who can access which endpoints.
  • Rate Limits & Quotas: Providers throttle requests to protect infrastructure and ensure fair use.

Real-time APIs may use WebSockets or server-sent events for streaming data rather than repeated HTTP polling. Designing for observability—clear logs, metrics, and error messages—improves operational resilience.

Common API Types and Protocols

Different projects require different API styles. Choosing a style depends on latency, flexibility, compatibility, and developer experience needs.

  • REST: Representational State Transfer emphasizes resources and standard HTTP verbs. RESTful APIs are easy to cache and widely supported.
  • GraphQL: Clients request exactly the fields they need in a single query, reducing over-fetching. GraphQL adds flexibility but requires careful performance tooling.
  • SOAP: An XML-heavy protocol that offers strict contracts and built-in standards for security and transactions; common in enterprise systems.
  • gRPC / Protobuf: High-performance RPC frameworks for microservices with compact binary payloads and strict typing.
  • Webhooks: Reverse-style APIs where a service pushes events to your endpoint, useful for near-real-time notifications without polling.

APIs are often packaged with SDKs for languages like Python, JavaScript, or Go to simplify integration. Documentation, example requests, and interactive consoles dramatically improve adoption.

APIs in Crypto and AI: Use Cases and Considerations

APIs are central to crypto and AI ecosystems. In crypto, APIs provide market data (prices, order books), on-chain insights (transaction history, token balances), and node RPC endpoints for smart contract interaction. AI systems use APIs to host inference endpoints, orchestrate models, and integrate external data sources for context.

Key considerations when selecting or building APIs for these domains:

  • Data Accuracy: In finance and blockchain, stale or inconsistent data can lead to incorrect analysis. Verify timestamps, aggregation logic, and reconciliation methods.
  • Latency and Throughput: Trading or real-time analytics may require low-latency streaming or websocket feeds instead of periodic REST calls.
  • Security: Protect API keys, enforce least privilege, use encrypted transport (HTTPS/TLS), and monitor for anomalous request patterns.
  • Reliability: Redundancy, caching strategies, and graceful degradation help maintain service if a provider faces outages.
  • Compliance & Privacy: Understand data retention, user privacy, and jurisdictional constraints when handling labeled or personal data.

Tools like Token Metrics combine market and on-chain data with AI to support research workflows that depend on reliable API feeds and model-driven signals.

What is the difference between REST and GraphQL?

REST exposes multiple endpoints representing resources; clients may need several calls to assemble data. GraphQL exposes a single query endpoint where clients request precisely the fields they need. REST is simpler to cache; GraphQL offers flexibility but can require extra server-side tooling to manage complex queries and performance.

How do I secure an API key?

Never embed keys in client-side code. Store keys in secure server environments or secrets managers, rotate keys periodically, apply scope and rate limits, and monitor usage. Implementing short-lived tokens and IP whitelisting adds protection for sensitive endpoints.

When should I use webhooks instead of polling?

Use webhooks when you need event-driven, near-real-time notifications and want to avoid the overhead of frequent polling. Webhooks push updates to your endpoint, but require you to handle retries, verify payload signatures, and secure the receiving endpoint.

Can I build an API for my blockchain node?

Yes. Many projects wrap node RPCs with REST or GraphQL layers to standardize queries and add caching, rate limiting, and enrichment (e.g., token metadata). Be mindful of node sync status, resource consumption, and privacy considerations when exposing node endpoints.

How do I evaluate an API provider?

Assess API documentation quality, uptime/SLAs, latency, data freshness, authentication options, and support channels. Request sample data, test in sandbox environments, and compare pricing with expected usage. For crypto use cases, verify on-chain data coverage and reconciliation methods.
