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.
The part I actually care about: your agent pays per call. No account, no card, no API key to babysit.
Why I got tired of the usual vendors
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.
So the whole point here is to skip that.
What is in it
Around 267 resources right now. A few examples:
- XAUUSD signal with entry, stop, and target
- Live Binance order book depth
- On-chain stuff: MVRV, SOPR, NUPL, Fear and Greed
- China macro snapshot: GDP, CPI, PMI, LPR, USD/CNY
- DeepSeek and NovaMind chat endpoints
Most are REST and return JSON. You pipe the response straight into whatever your agent is doing.
How the payment works
Each paid call costs from $0.01 and settles in USDC on Base, using the x402 protocol. The sequence is boring and automatic:
- Your agent hits the endpoint
- The server answers 402 with the price
- Your x402 client signs a USDC transfer and retries
- You get the data
No human in the loop. A brand new agent wallet just pays as it goes.
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:
curl -H "X-Wallet: 0xYOUR_WALLET" \

Calling it from code
With an x402-aware HTTP client, the 402 handshake happens for you:
resp = x402_client.get("https://agentdatum.com/api/v1/crypto/onchain")
print(resp.json()) # MVRV, SOPR, NUPL, Fear and Greed
The honest tradeoff
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.
