Yelp

Overview

Yelp is a free public API in the Open Data category. Find Local Business.

This API belongs to the Open Data category, a popular area of the free-API ecosystem for builders.

You can use this API in prototypes, side projects, and production applications — just keep the provider’s usage policy in mind.

Authentication

Yelp uses OAuth for authentication. You will typically need to:

1. Register an application with the provider to get client credentials.
2. Implement the authorization flow described in the official docs.
3. Exchange the authorization code for an access token.

The official documentation is the authoritative source for scopes, token expiry, and refresh mechanics.

HTTPS & CORS

• HTTPS: not supported — Yelp is served over plain HTTP only. Avoid sending sensitive data, and prefer HTTPS endpoints where possible.
• CORS: unknown — if you plan to call Yelp from the browser, verify CORS support in the official docs or with a quick test request.

Getting Started

1. Read the official documentation: https://www.yelp.com/developers
2. Set up authentication (see Authentication above).
3. Make a test request with curl or your favourite HTTP client.

Rate Limits & Notes

• Rate limits, quotas, and free-tier terms are defined by the provider — always check the official documentation for Yelp before scaling up.
• The upstream listing is community-maintained; fields like auth, HTTPS and CORS reflect the state at listing time and may change.
