This document lists requirements for applications developed with the Street View Static API. Note that use of the Street View Static API is governed by your Agreement with Google.
Pre-Fetching, Caching, or Storage of Content
Applications using the Street View Static API are bound by the terms of your Agreement with Google. Subject to the terms of your Agreement, you must not pre-fetch, index, store, or cache any Content except under the limited conditions stated in the terms.
Note that the panorama ID, used to uniquely identify a Street View panorama, is exempt from the caching restriction. Therefore, you can store panorama ID values indefinitely. Panorama ID values are returned in the pano field in Street View Static API responses.
Style guidelines for Google attribution
Following are style guidelines for Google attributions in CSS and HTML if you're not able to use the downloadable Google logo.
The amount of clear space around the lockup should be equal to or greater than the height of the "G" in Google.
The space between the attribution copy and the Google logo should be half the width of the "G".
The byline should always be clear, legible, and appear in the right color variation for a given background. Always be sure to provide enough contrast for the logo variation that you select.
Use Google Material Gray 700 text on a white or light background that uses a range of 0%–40% maximum tint of black.
#5F6368 RGB 95 99 104 HSL 213 5 39 HSB 213 9 41
On darker backgrounds, and over photography or non-busy patterns, use white text for byline and attribution.
#FFFFFF RGB 255 255 255 HSL 0 0 100 HSB 0 0 100
Use the Roboto font.
The following CSS, when applied to the text "Google," would render "Google" with the appropriate font, color, and spacing on a white or light background.
font-family: Roboto; font-style: normal; font-weight: 500; font-size: 16px; line-height: 16px; padding: 16px; letter-spacing: 0.0575em; /* 0.69px */ color: #5F6368;
