雅虎财经有多可靠？

例如下面的请求:
http://developer.yahoo.com/yql/console/?q=show%20tables&env=store://datatables.org/alltableswithkeys#h=select%20 *%20from%20yahoo.finance.quotes%20where%20symbol%20in%20%28%22YHOO%22%2C%22AAPL%22%2C%22GOOG%22%2C%22MSFT%22%29

间歇性返回响应:“当前表'yahoo.finance.quotes'已被阻止。它超出了时间或指令的分配配额”

这是完整的回复:

<?xml version="1.0" encoding="UTF-8"?>
<query xmlns:yahoo="http://www.yahooapis.com/v1/base.rng"
    yahoo:count="0" yahoo:created="2013-04-08T11:16:18Z" yahoo:lang="en-US">
    <diagnostics>
        <publiclyCallable>true</publiclyCallable>
        <url execution-start-time="24" execution-stop-time="25"
            execution-time="1" proxy="DEFAULT"><![CDATA[http://www.datatables.org/yahoo/finance/yahoo.finance.quotes.xml]]></url>
        <cache execution-start-time="27" execution-stop-time="27"
            execution-time="0" method="GET" type="MEMCACHED"><![CDATA[13c4f8eac77ad886bade5a711c8c1ef5]]></cache>
        <javascript name="yahoo.finance.quotes" verb="select"><![CDATA[The current table 'yahoo.finance.quotes' has been blocked. It exceeded the allotted quotas of either time or instructions]]></javascript>
        <user-time>28</user-time>
        <service-time>1</service-time>
        <build-version>35405</build-version>
    </diagnostics>
    <results/>
</query>

要获得可靠的服务，我是否需要注册并付款？

最佳答案

以下是限制:

                    Public  OAuth with API Key
Hourly Cap          2,000   20,000
Daily Cap           None    100,000

oAuth 是 free 。
