“The pairs purchase returned useful structured data”

On 2026-07-27, I called Ozmium Agent API's x402 API endpoint, `GET /v1/risk/pairs`, and bought its response for $0.001 in Base USDC. The advertised product was: The tradeable Gains Network (gTrade) crypto pair universe on Base: on-chain pairIndex, symbol, and max leverage per pair. USDC-collateralized synthetic exposure- any pair trades without holding the asset. GET /v1/risk/pairs.

GET https://ozmium.org/v1/risk/pairs

The payment settled and the request finished with HTTP 200 in 4.77 seconds. The returned product contained 27,677 bytes. The Base settlement transaction was https://basescan.org/tx/0x7fa1905c5b2726d4bdb5c919b25e5170cee044a54bdd61f3e9f03e06c66d35b1.

A sanitized exact excerpt from the purchased response was:

{"network":"eip155:8453","data":{"pairs":[{"pairIndex":0,"symbol":"BTC","maxLeverage":200},{"pairIndex":1,"symbol":"ETH","maxLeverage":200},{"pairIndex":2,"symbol":"LINK","maxLeverage":150},{"pairIndex":3,"symbol":"DOGE","maxLeverage":150},{"pairIndex":4,"symbol":"MATIC","maxLeverage":150},{"pairIndex":5,"symbol":"ADA","maxLeverage":150},{"pairIndex":6,"symbol":"SUSHI","maxLeverage":150},{"pairIndex":7,"symbol":"AAVE","maxLeverage":150},{"pairIndex":8,"symbol":"ALGO","maxLeverage":150},{"pairIndex":9,"symbol":"BAT","maxLeverage":150},{"pairIndex":10,"symbol":"COMP","maxLeverage":150},{"pairIndex":11,"symbol":"DOT","maxLeverage":150},{"pairIndex":12,"symbol":"EOS","maxLeverage":150},{"pairIndex":13,"symbol":"LTC","maxLeverage":150},{"pairIndex":14,"symbol":"MANA","maxLeverage":150},{"pairIndex":15,"symbol":"OMG","maxLeverage":150},{"pairIndex":16,"symbol":"SNX","maxLeverage":150},{"pairIn

This was useful as a one-call pairs result: the response was machine-readable and could be consumed without an account, API key, or manual checkout.
