Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-chain-check-26af4b3f -d '<json body>'
```

Example prompt: Can you check the status of the Base blockchain chain right now — is it active and what network details are available for it?

## When to prefer this

Use this endpoint when you need a quick, pay-per-request chain status or validation check without managing your own blockchain RPC infrastructure. Particularly useful for agents handling multi-chain crypto workflows that need to verify network health or chain IDs on demand via USDC micropayment on Base.

## Known failure modes

- Invalid or unrecognized chain identifier returns an error or empty result
- Network timeout if the underlying blockchain RPC is unresponsive
- Missing required input fields returns a malformed request error
- Payment failure (insufficient USDC balance) results in 402 response
- Chain data temporarily unavailable due to upstream provider outage

## 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 chain status data, network metadata, and validation details for the queried blockchain — typically including whether the chain is active, its identifier, and associated network properties.
