Legacy APIs Depreciation Note

Applications written on top of the Legacy Fetch and Search APIs no longer work because these services have been discontinued. The new APIs are totally revamped and are completely different from the old APIs. Therefore, we have updated the documentation with comparative examples of the legacy as well as revamped APIs. You can get started with the new APIs by visiting the RCSB Data API and RCSB Search API documentation pages.
