      <title>AgentDataHub: a data marketplace your agent can pay for by itself</title>

      <description>&lt;p&gt;I built something annoying to explain at parties, so here is the short version. AgentDataHub is 267 data endpoints you can call from code. Gold signals, crypto on-chain metrics, China macro numbers, a couple of chat models. Most return plain JSON.&lt;/p&gt;

&lt;p&gt;The part I actually care about: your agent pays per call. No account, no card, no API key to babysit.&lt;/p&gt;

&lt;h2&gt;
  
  
  Why I got tired of the usual vendors
&lt;/h2&gt;

&lt;p&gt;Every data provider wants the same thing before you get a single number. Sign up. Add a card. Generate a key. Negotiate rate limits. Agree to a monthly minimum you will never hit. I just wanted to ask for the XAUUSD signal and move on.&lt;/p&gt;

&lt;p&gt;So the whole point here is to skip that.&lt;/p&gt;

&lt;h2&gt;
  
  
  What is in it
&lt;/h2&gt;

&lt;p&gt;Around 267 resources right now. A few examples:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;XAUUSD signal with entry, stop, and target&lt;/li&gt;
&lt;li&gt;Live Binance order book depth&lt;/li&gt;
&lt;li&gt;On-chain stuff: MVRV, SOPR, NUPL, Fear and Greed&lt;/li&gt;
&lt;li&gt;China macro snapshot: GDP, CPI, PMI, LPR, USD/CNY&lt;/li&gt;
&lt;li&gt;DeepSeek and NovaMind chat endpoints&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Most are REST and return JSON. You pipe the response straight into whatever your agent is doing.&lt;/p&gt;

&lt;h2&gt;
  
  
  How the payment works
&lt;/h2&gt;

&lt;p&gt;Each paid call costs from $0.01 and settles in USDC on Base, using the x402 protocol. The sequence is boring and automatic:&lt;/p&gt;

&lt;ol&gt;
&lt;li&gt;Your agent hits the endpoint&lt;/li&gt;
&lt;li&gt;The server answers 402 with the price&lt;/li&gt;
&lt;li&gt;Your x402 client signs a USDC transfer and retries&lt;/li&gt;
&lt;li&gt;You get the data&lt;/li&gt;
&lt;/ol&gt;

&lt;p&gt;No human in the loop. A brand new agent wallet just pays as it goes.&lt;/p&gt;

&lt;p&gt;If you do not want to spend yet, anonymous users get 1,000 free credits a month. Send your wallet in the X-Wallet header:&lt;br&gt;
&lt;/p&gt;

&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight shell"&gt;&lt;code&gt;curl &lt;span class="nt"&gt;-H&lt;/span&gt; &lt;span class="s2"&gt;"X-Wallet: 0xYOUR_WALLET"&lt;/span&gt; &lt;span class="se"&gt;\&lt;/span&gt;
  https://agentdatum.com/api/v1/gold/signal
&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;



&lt;h2&gt;
  
  
  Calling it from code
&lt;/h2&gt;

&lt;p&gt;With an x402-aware HTTP client, the 402 handshake happens for you:&lt;br&gt;
&lt;/p&gt;

&lt;div class="highlight js-code-highlight"&gt;
&lt;pre class="highlight python"&gt;&lt;code&gt;&lt;span class="n"&gt;resp&lt;/span&gt; &lt;span class="o"&gt;=&lt;/span&gt; &lt;span class="n"&gt;x402_client&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nf"&gt;get&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="s"&gt;https://agentdatum.com/api/v1/crypto/onchain&lt;/span&gt;&lt;span class="sh"&gt;"&lt;/span&gt;&lt;span class="p"&gt;)&lt;/span&gt;
&lt;span class="nf"&gt;print&lt;/span&gt;&lt;span class="p"&gt;(&lt;/span&gt;&lt;span class="n"&gt;resp&lt;/span&gt;&lt;span class="p"&gt;.&lt;/span&gt;&lt;span class="nf"&gt;json&lt;/span&gt;&lt;span class="p"&gt;())&lt;/span&gt;  &lt;span class="c1"&gt;# MVRV, SOPR, NUPL, Fear and Greed
&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;

&lt;/div&gt;



&lt;h2&gt;
  
  
  The honest tradeoff
&lt;/h2&gt;

&lt;p&gt;It is cheap and it is zero-setup, which is exactly what small agents and weekend projects need. The catalog is broad but not deep in any one area yet. If you need institutional-grade coverage of a single market, this is not that. If you want to wire up a dozen data points across crypto, gold, and macro without talking to a sales team, it probably saves you a weekend.&lt;/p&gt;

&lt;p&gt;Full catalog lives at &lt;a href="https://agentdatum.com/.well-known/ai-catalog.json" rel="noopener noreferrer"&gt;https://agentdatum.com/.well-known/ai-catalog.json&lt;/a&gt;&lt;/p&gt;
