As of January 2020, CoinMarketCap data suggests that there are 13,847,549 API3 in circulation — out of a maximum supply of 100 million tokens.
While 15 million tokens have been distributed among pre-seed and seed investors, a further 20 million tokens were reserved for a public token distribution event that took place over the first two weeks of December. The founding team was allocated 30 million tokens, with 10 million going to partners and contributors. And finally, 25 million went to an ecosystem fund.
Tokens sold during a public sale are unlocked, but seed investors and founders are subject to a vesting period of between two and three years.
