API Finder

Search public APIs by keyword or category, filter for HTTPS and CORS signals, and review documentation links before a project integration.

Search API names, descriptions, and categories before opening provider documentation.

Filter broad API ideas by category, HTTPS availability, and CORS status.

  • Find public APIs by category
  • Review HTTPS and CORS signals
  • Open documentation links faster

How to use API Finder

Use this flow to move from a broad API idea to a shorter list of candidates worth checking in provider documentation.

  1. 1

    Search for an API topic

    Search for the data or service you need, such as weather, email, finance, maps, media, security, or test data, then scan matching API names.

  2. 2

    Narrow the candidate list

    Narrow the directory with category, HTTPS, CORS, and auth filters so the result list better matches your frontend, backend, or no key testing needs.

  3. 3

    Check provider documentation

    Open or copy the promising documentation links, then verify pricing, authentication, rate limits, terms, response format, and maintenance status with the API provider before building.

Public API directory search

Search API names, descriptions, and categories from the bundled public API directory snapshot without leaving the tool page.

Category-first discovery

Move from a broad idea to focused categories such as finance, location, media, weather, security, education, or developer tools.

HTTPS and CORS filters

Filter for HTTPS availability and CORS signals when browser projects, static sites, or frontend prototypes need extra compatibility checks.

Documentation link review

Open the listed documentation for likely candidates so pricing, authentication, examples, limits, and terms can be verified at the source.

No account browsing

Browse and filter API candidates without creating a profile, which keeps early research useful for classes, demos, and quick experiments.

Large list scanning

Use the loaded result list to compare similar APIs, save promising names, and build a shortlist before deeper integration testing.

API Finder privacy and processing

API Finder explains that search settings go to the server-assisted app route, results come from the bundled directory snapshot, and final suitability should be verified before integration.

Processing Server-assisted

API Finder sends search and filter settings to the app route, which reads the local directory snapshot and returns matching API candidates for review.

Storage None

API Finder keeps the visible result list in the current session only. Refreshing, filtering, or searching again changes the displayed candidates.

API Finder account access

API Finder supports guest use for public API research, category scans, documentation review, and quick prototype planning from this page.

Before You Use API Finder

Review these notes before choosing an API for a prototype, production feature, school project, automation, or internal developer task.

Privacy

Search with generic project terms when possible, especially if the idea comes from a private client, employer, or unreleased product.

Do not paste secrets, API keys, customer data, or private endpoint names into the search box while comparing public options.

Accuracy

Directory entries can become stale, so confirm pricing, authentication, rate limits, uptime, and maintenance on the provider site.

A matching category does not prove the API fits your data model, compliance rules, latency needs, or production support expectations.

Compatibility

CORS status matters for browser apps, while backend integrations may care more about authentication, rate limits, SDKs, and response formats.

HTTPS support is important, but it does not guarantee stable documentation, generous limits, commercial use rights, or long-term availability.

Output

Use the results as a research shortlist, then test the chosen API in your actual frontend, backend, spreadsheet, or automation environment.

Keep notes on the provider URL, authentication type, terms, rate limits, sample endpoint, and fallback option before committing to one API.

Limits

API Finder searches the local public API directory snapshot by name, description, and category; very broad queries can return many candidates to review.

API Finder depends on the local API search route and bundled directory data, so stale entries or route errors can affect candidate results.

Questions about API Finder

What is a public API finder?

A public API finder helps you search APIs that expose data or services for apps, prototypes, automations, and learning projects. This page focuses on fast candidate discovery.

How should I choose an API from the results?

Start with category fit, HTTPS, CORS, and documentation quality, then confirm authentication, pricing, terms, rate limits, examples, and current provider maintenance.

Does API Finder require an account?

No. API Finder can search and filter the bundled public API directory without sign-in, but production API usage may still require a provider account or key.

Are the listed APIs guaranteed to work?

No. Treat the directory as a starting point. APIs can change pricing, authentication, domains, rate limits, and uptime, so verify details before building on one.
