持续或周期免费Recurring free access
想长期测试时，先看永久或周期恢复额度。For longer evaluation, start with permanent or recurring allowances.
01 / 30-second decision
30 秒怎么选Choose in 30 seconds
国内免费 API 先看额度是否持续，再看实名、账号绑定和兼容性。For China-based free APIs, check whether the allowance recurs, then review identity, account-binding and compatibility requirements.
新人 / 公测 / 限免Trial, preview or limited-time
这类额度可能一次性或随活动结束，接入前先看有效期。These allowances may be one-time or end with a promotion, so check validity before integrating.
