Overview

Pexels API provides free access to a large library of high-quality stock photos and videos contributed by talented creators, all under the Pexels license. You can search for photos and videos by keyword, browse curated collections, and get popular media with a single API key. It is an excellent choice for developers who need royalty-free imagery without dealing with licensing complexity.

Beginner Tip

Your Pexels API key must be included as the Authorization header (not with Bearer prefix, just the raw key) in every request. Always attribute photos to the photographer using the photographer and photographer_url fields as required by the Pexels license.

Available Data

The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.

Example Response

Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.

Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

Request 
const url = "https://api.pexels.com/v1/search?query=mountains&per_page=5";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "X-API-Key": "YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.

401 Unauthorized The Authorization header is missing or contains an invalid API key.
✓ Include the header Authorization: YOUR_API_KEY (without Bearer prefix) in every request; get your key from https://www.pexels.com/api/.
429 Too Many Requests You have exceeded the rate limit of 200 requests per hour or 20,000 per month on the free plan.
✓ Cache API responses to reduce repeated calls, and implement a retry with delay when you receive a 429 response.
Empty results array The search query returned no matching photos, often due to a very specific or misspelled term.
✓ Try broader or simpler search terms, and always check the total_results field before iterating over the photos array.

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
