## 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 kiteendpoints-ai-mega-api-hub-coinbase-payment-gateway-18f0052f -d '<json body>'
```

Example prompt: Call the KiteEndpoints Mega API Hub via the Coinbase x402 endpoint, paying 0.19 USDC on Base chain, and fetch me the latest crypto price data — send the result object back once the payment clears.

## When to prefer this

Choose this endpoint when you need to call one of the 400+ aggregated APIs (social, AI, crypto, finance, weather, ecommerce) and want to pay per request in USDC on Base chain via x402 protocol, without managing individual API keys or subscriptions for each provider.

## Known failure modes

- Payment failure: insufficient USDC balance or Base chain transaction rejection
- Ambiguous routing: the generic input schema means the wrong sub-endpoint may be invoked
- Empty or example response: endpoint may return placeholder {data: 'example response'} if not properly configured
- 402 Payment Required: x402 handshake fails if payment header is missing or malformed
- Timeout: underlying sub-API may be slow or unavailable
- Schema mismatch: input does not match the expected format for the specific sub-API being called

## How this service works

400+ paid API endpoints. Social media, AI, crypto, finance, weather, ecommerce, tools. Pay per request with USDC on Base chain.

## Output

Returns a result object containing the API response data from whichever underlying endpoint was called; structure varies by the specific sub-API invoked but is wrapped in a standard {result: {data: ...}} envelope.
