How payment works (x402)

  1. Call the endpoint without any payment header → you get 402 Payment Required with the exact price, the USDC contract, the network (eip155:8453 = Base), and the pay-to address.
  2. Pay 0.01 USDC on Base to the pay-to address — with any wallet, the Coinbase CDP x402 SDK, or any x402 client library.
  3. Retry the same request with the X-PAYMENT header set to the base64-encoded signed payment payload → 200 with JSON.
# 1. Get the 402 payment requirements
curl -s "https://contabo-vps.taild7e69a.ts.net/marketdata/api/market/overview"

# 2. Pay 0.01 USDC on Base, then retry with the payment proof
curl "https://contabo-vps.taild7e69a.ts.net/marketdata/api/market/overview" \
  -H "X-PAYMENT: <base64-signed-payment-payload>"

Free trial

Every IP gets 5/day free calls to this endpoint — no payment needed. Free calls run automatically when you call without an X-PAYMENT header. The X-Free-Remaining response header shows how many free calls you have left today. When the quota is exhausted, the request falls through to the normal 402 payment flow.

FAQ

What symbols are covered?
BTC, ETH, SOL plus SPY/QQQ/DIA ETFs and the VNINDEX.
How fresh is the data?
Prices refresh every ~60 seconds.
Can I get a single symbol?
This endpoint returns the full board. For single-token prices use /tokenprice.
Do I need an API key?
No. This API uses x402: call the endpoint, receive a 402 Payment Required with the price, pay in USDC on Base, and retry with the X-PAYMENT header. No signup, no API key, no account.
Which facilitators are supported?
Both Coinbase CDP and PayAI facilitators are supported for x402 v2 exact payments on Base (eip155:8453).
What if my payment is too low?
The facilitator verifies the on-chain amount against the price. If underpaid, you get 402 again; pay the full amount and retry.
