LetGo

letgo is a mobile-first classifieds and secondhand marketplace where individuals list, browse, and negotiate on used goods — vehicles, electronics, furniture, and household items — with chat-based buyer/seller messaging and location-based discovery. Launched in 2015 and backed by Naspers/OLX, letgo grew into one of the largest peer-to-peer resale apps in the United States before combining its US operation with OfferUp in 2020. The letgo brand and letgo.com continue to operate as a regional classifieds marketplace; the live site currently serves a Turkish-language catalog (category browsing, search, and an otoplus vehicles section per its robots.txt). letgo publishes no public developer program, API documentation, or SDKs. The application-internal API under /api/ is explicitly disallowed in robots.txt, and the entire site sits behind an Akamai bot-mitigation challenge, so no developer surface could be verified.

LetGo is profiled on the APIs.io network. Tagged areas include Company, Classifieds, Marketplace, Secondhand, and Peer to Peer Commerce.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/letgo: open an issue to ask a question, or submit a pull request to add artifacts.
