## Rules to follow
- Credit Robohash.org (for example "Robots lovingly delivered by Robohash.org") wherever the images are shown, under CC-BY.
- Request images from https://robohash.org/YOUR-TEXT.png and use ?set=, ?size= and ?bgset= parameters to choose style.
- Use an explicit set such as ?set=set1 rather than set=any, because set=any can change existing hashes when new sets are added.
- Do not hash personal data such as an email in plain text; use the hashed form with ?gravatar=hashed.

## How an agent gets files
- Request https://robohash.org/YOUR-TEXT.png; choose style with ?set=set1..set6, ?size=200x200, ?bgset=bg1; change the extension to get another format. (sign-in: none)
- Formats: png, jpg, bmp
- Credit line: `Robots lovingly delivered by Robohash.org`
- Not allowed: Credit under CC-BY; the page also lists set artists (set1 Zikri Kader, set2 Hrvoje Novakovic, set3 Julian Peter Arias, set4 David Revoy, set5 Pablo Stanley, set6 OceanSlim)
- Not allowed: Use an explicit set, not set=any, because existing hashes may change when sets are added
- Not allowed: The site may add a Robohash.org banner to images if bandwidth gets heavy

AgentGid's catalog is curated: every entry was checked against the maker's official pages (registry, repository, license and pricing pages) on the date shown; a license value shows the quote it stands on wherever AgentGid has one. Usage numbers come from AgentGid's own scan of public repositories set up for AI coding agents. Claims by makers are reported, not tested by AgentGid.
