holidays.rest

holidays.rest provides the most accurate and comprehensive holiday data delivered at blazing speed for customers at any scale. Cover national, public, and religious holidays for 190+ countries in milliseconds with our RESTful API. We take pride in delivering authentic, accurate data. Our API exclusively offers real historical information without artificial records. For example, it recognizes that October 3rd wasn’t German Unity Day in 1985 because Germany wasn’t unified at the time—something many other APIs fail to account for. We also don’t provide fictional data. The United Nations recognizes 195 countries, with an additional 9 partially recognized states. Unlike others, we don’t exaggerate by claiming to cover 250 countries. Our pricing is straightforward: all plans give you full access to the capabilities of our API, without restrictions on parameters or features. No hidden limitations—just simplicity.

CodeRifts

CodeRifts is signed, offline-verifiable authorization for API-contract changes. Before a change to an OpenAPI, GraphQL, protobuf, AsyncAPI or MCP tool contract merges, deploys or publishes, CodeRifts decides whether it is authorized and signs the decision into a receipt that anyone can verify without CodeRifts — MIT verifiers in JavaScript and Python, no API key, no database to trust. A GitHub required check makes the decision enforcing: without a valid receipt for the pull request's actual diff, the merge is blocked. MCP tools, an SDK and a CLI let AI agents ask before they change a contract; the agent branches on one field, execution_action. Breaking-change detection, risk scoring and policy checks are the analysis underneath, free for public repositories. Every decision states what it does not prove. Only a granted change can proceed. Supports GitHub App and Actions, GitLab CI (API derivation), CLI, REST API and the MCP protocol.

Zunoy MockAPI

Mentcube Innovations Pvt Ltd

Zunoy MockAPI - a game changer for developers looking to create and use mock APIs without needing to set up a full backend service. It's ideal for those times when you just can't wait for the actual API to be ready, whether it's a matter of frontend dev, testing, or prototyping. Quick to get up and running, users can whip up mock endpoints in no time, define the request & response data, and make the whole thing behave just like a real API - totally on point for development & testing purposes. This platform really does make life easier for teams to keep on working independently, regardless of whether the backend is ready or not - no dependencies to hold things up. You can test integrations, validate app workflows & show off product concepts, all with realistic API responses. The truth is, MockAPI is a real lifesaver for building prototypes, testing apps, speeding up dev cycles & reducing delays caused by a half-built backend.

ReqKey

ReqKey adds API key authentication, usage credits, rate limiting and request analytics to an API you own. Your own middleware makes a single verify call per incoming request: ReqKey validates the caller’s key, deducts a credit from that consumer’s pool, enforces their rate limit, and records the request with status code, latency and location. It never sits in front of your API — no proxy, no gateway, no DNS change — so it adds no hop to your critical path. Validation averages under 5ms. Credits pool per consumer rather than per key, so issuing a customer a second key does not hand them a second quota, and balances stay synced across regions. Also included: shadow limits, controlled overage, reusable plans, low-credit alerts, and per-request logs filterable by endpoint, status, consumer and time range. ReqKey meters and tracks usage — you keep your own billing stack. SDKs for Python, Node.js, Go, Rust, PHP, .NET and Java, with framework adapters for FastAPI, Express, Django, and more.
