Beach Day API

Beach Day API is a developer-first REST API and MCP server for real-time beach, ocean, water quality, weather, tide, and coastal condition data. The API answers one simple question: **is it a good day to go to the beach?** Instead of scraping government websites, locating marine stations, parsing water quality reports, and combining multiple coastal data sources, developers can retrieve structured beach intelligence through clean JSON responses from a single API. Beach Day API currently covers **36,000+ beaches across 110 countries** worldwide, with data that can include water quality grades, bacterial contamination information, advisories and closures, current weather, ocean conditions, wave height and period, water temperature, air temperature, wind, UV index, tide predictions, beach rules, amenities, GPS coordinates, access information, and lifeguard details. Each beach can also include a proprietary **Beach Day Score from 0 to 100**, giving applications an easy way to summarize current conditions. Developers can use the score to rank beaches, filter recommendations, create alerts, or quickly communicate whether conditions look favorable for a visit. Beach Day API is designed for travel apps, weather apps, beach finder tools, tourism platforms, vacation rental services, local news products, coastal safety tools, smart-home automations, real estate applications, AI assistants, autonomous agents, and other products that need structured beach and coastal data. The API includes endpoints for searching beaches, retrieving complete beach details, checking current conditions, accessing 7-day tide predictions, viewing rules and amenities, listing countries, and finding beaches ranked by their current Beach Day Score. ### Built for developers and AI agents Beach Day API can be accessed through its traditional REST API or through the **Model Context Protocol (MCP)** for compatible AI assistants and agents. MCP tools allow AI systems to search beaches, retrieve beach information, check conditions and water quality, evaluate Beach Day Scores, and work with coastal data directly. Beach Day API also supports autonomous-agent infrastructure using OAuth and workload identity. Compatible agents can discover onboarding requirements, authenticate, inspect their credit balance, and interact with Beach Day API through MCP. For compatible agent payment systems, Beach Day API supports machine-initiated credit purchases using the **Machine Payments Protocol (MPP)** and HTTP 402 payment challenges, providing infrastructure for agent-driven API usage and payments. ### Multiple ways to integrate Official client libraries are available for Python and Node.js: **Python:** `pip install beachdayapi` **Node.js:** `npm install beachdayapi` Beach Day API is also available through integrations and marketplaces including **RapidAPI, Apify, Zapier, Apyhub, API.market, APIDog, and n8n**. The Beach Day API n8n node is verified for n8n Cloud. A community Home Assistant integration can also bring beach conditions into smart-home dashboards and automations. ### Simple prepaid pricing New developers receive **50 free API credits with no credit card required**. Beach Day API uses prepaid credits with no required monthly subscription or automatic billing. Current packages include 2,000 credits for $20, 5,000 credits for $50, and 22,000 credits for $200. Purchased credits remain valid for one year. Beach Day API has now served **more than 1 million API requests** and provides a single coastal data layer for developers who want beach intelligence without maintaining their own collection of government, municipal, weather, marine, tide, and water-quality integrations. Whether you are building a beach recommendation app, travel assistant, tourism platform, coastal safety system, automated workflow, smart-home dashboard, or AI agent, Beach Day API provides the structured data needed to build faster.
