Second Life Live Data Feeds
Anonymous, unauthenticated feeds publishing live Second Life grid statistics (grid status, total registered accounts, avatars currently inworld) and LindeX currency-market data (limit and market buy/sell rate ranges and volumes over the last hour, last day and today, plus the best-10-percent offer book). Served in three formats — a bespoke two-line key/value text format, plain XML, and LLSD XML. Signups update daily, the inworld count every 3 minutes, LindeX every 15 minutes. The only Second Life API reachable with no credential of any kind.
