## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability speraxos-token-markets-data-api-cacc29c8 -d '<json body>'
```

Example prompt: Pull up the current token market data for USDC on Base from SperaxOS — I want to see price, volume, and market metrics without setting up an API key.

## When to prefer this

Choose this endpoint when you need DeFi token market data with no API key setup, are already operating in a crypto-native or Base ecosystem context, and can pay per request in USDC via x402. Ideal for agents that make infrequent or dynamic queries where subscription APIs are overkill, or when building permissionless, wallet-native data pipelines.

## Known failure modes

- Payment not received or insufficient USDC balance — returns 402 Payment Required
- Invalid or unsupported token identifier — returns empty or error response
- Token not tracked by SperaxOS — no data returned
- Network issues on Base chain causing payment verification failure
- Malformed properties filter parameter — schema validation error

## How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

## Output

Returns token market data including price, trading volume, liquidity, market cap, and other DeFi intelligence metrics for the queried tokens. Response is delivered after micropayment of $0.001 USDC on Base via the x402 protocol.
