TransportAPI

TransportAPI provides managed services for accessing and publishing UK transport data through APIs. Its Journey Planner covers bus, train, metro, coach, tram, light rail, cycle, car, ferry and taxi journeys across Great Britain. Bus Information and Rail Information provide nationwide scheduled and real-time data through APIs or GTFS. The services monitor data quality and report errors to data vendors so they can be addressed at source. API options include polling and streaming, with RESTful JSON and, for some services, Websocket JSON-RPC. Journey Planner engine options include SilverRail, TfL API, OTP, R5, OSRM, CycleStreets and TaxiCode. Bus Information combines UK datasets such as TNDS, BODS, NaPTAN, BODS SIRI VM and Traveline Nextbuses SIRI SM. The services are intended for apps and websites, transport analytics and data mining. A free plan costs nothing and allows 30 API hits per day, free forever. The Home user plan lists 300 requests per day, billed monthly, with no price stated. Trial periods are available.

TransportAPI offers broad UK journey planning alongside nationwide bus and rail data, with API and GTFS access. The free plan has a stated daily request limit, while the Home user plan lists no price.

It suits developers and organizations building transport apps or websites, as well as users working with transport analytics or data mining. Separate email contacts are listed for technical support, account support and business enquiries.

TransportAPI is a managed service for accessing and publishing UK transport data through APIs. It suits teams building journey-planning apps, transport websites or data-analysis workflows that need nationwide bus and rail feeds. Its range is useful, but the free tier’s 30 daily API hits is modest for anything beyond a small evaluation.

Overview

TransportAPI combines journey planning with scheduled and real-time transport information for Great Britain. Its services are designed for apps and websites as well as transport analytics and data mining, rather than as a standalone consumer travel app.

The service launched in 2012 and is operated under the official company name Placr Limited. A notable advantage for teams building on the data is TransportAPI’s stated policy that it does not retain downstream rights in customer-created or developed work, and permits customers to use that work as they see fit.

Key features

TAPI Journey Planner covers bus, train, metro, coach, tram, light rail, cycle, car, ferry and taxi journeys across Great Britain. That breadth makes it relevant to products that combine several modes; the choice of routing engine can also be matched to an integration, with options including SilverRail, TfL API, OTP, R5, OSRM, CycleStreets and TaxiCode.

TAPI Bus Information and TAPI Rail Information provide nationwide schedules and real-time data through API or GTFS. The bus service combines datasets such as TNDS, BODS, NaPTAN, BODS SIRI VM and Traveline Nextbuses SIRI SM. Managed data-quality monitoring reports errors to vendors for correction at source, a practical strength for teams that need data problems surfaced rather than simply passed downstream.

Managed services support polling and streaming, including RESTful JSON and, for some services, Websocket JSON-RPC. Separate email contacts for technical support, account support and business enquiries help distinguish operational questions from commercial ones.

Pricing

The Free plan costs nothing and includes 30 API hits per day, free forever. That cap makes it suitable for a small prototype or limited evaluation, but not a high-traffic service.

The Home user plan has custom pricing, is billed Monthly and allows 300 requests per day. Its higher allowance may suit modest personal or home use, but the daily ceiling remains a constraint for production workloads. TransportAPI also offers a free trial: managed-service trial periods are available, and the developer portal describes trials of paid plans with higher allowances.

Platforms

TransportAPI lists Android, iOS, web and API platforms. The platform range supports both app-facing and web-based projects, while the API is the core route for accessing its transport services.

Who it's for

TransportAPI is best suited to developers and organizations creating UK travel tools or working with transport data at scale across modes. Its nationwide bus and rail coverage, multiple API formats and data-quality process are useful when the project depends on regular feeds. A user who only needs occasional requests may find the free allowance sufficient; teams needing sustained volume should assess the paid plan’s 300-request daily limit against their workload.

Pros and cons

• Pro: Journey planning spans ten transport modes across Great Britain, giving multimodal products broad coverage.
• Pro: Nationwide scheduled and real-time bus and rail data are available through API or GTFS, with monitoring that flags source-data errors.
• Pro: Customers retain freedom to use their own work built with the data, under TransportAPI’s stated terms.
• Con: The free plan’s 30 daily hits sharply limits ongoing use beyond evaluation or very small projects.
• Con: The Home user plan raises the cap only to 300 requests per day, which may not fit a busy app or analytics pipeline.
• Con: The Home user plan’s custom pricing makes it harder to judge cost before committing.

Alternatives

For broader integration tooling rather than a UK transport-data service, compare the API Integration Platforms category. Knit may fit teams seeking API integration with a published Start Up plan at $499 a month, including 100K API calls/month, unlimited data usage, three test accounts and three-day log retention. Celigo is another freemium integration option, with a free plan limited to two endpoints, one flow and one production environment.

Nango is worth considering when connection and compute allowances are a better fit: its free plan includes 10 connections, 10 hours compute/month and 10GB data transfer/month. Workato Agent Studio instead offers a free plan with 50,000 one-time credits and AI and agentic capabilities. Apache Camel is a free option for teams looking for self-hosted software under Apache License 2.0.

Google Cloud Application Integration offers a free tier with up to 400 integration executions and up to 20 GiB processed per month. Pipedream has a free plan with development features, 3,000+ connectors and 10,000+ prebuilt tools and triggers. Superfeedr is an alternative for real-time feeds, with a free Hosted Hub plan that includes subscriber export and analytics.

Verdict

Choose TransportAPI if you are building a UK-focused product that needs broad journey planning or nationwide scheduled and real-time bus and rail data, especially when API and GTFS access and data-quality monitoring matter. Look elsewhere if your project needs a higher request ceiling or predictable published pricing: the free tier is tightly capped, and the Home user plan allows only 300 requests per day.
