## 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 apex-arc-fuci-pool-data-f9ae792f
```

Example prompt: Can you pull the current FUCI pool data from the Arc protocol — I want to see the pool head block, pool counts, burn proof, and whether the data is stale?

## When to prefer this

Use this endpoint when you need raw FUCI pool manager data from the Arc protocol including pool head, counts, burn proofs, and staleness status. Prefer this over general DeFi APIs when specifically working within the APEX/Arc ecosystem and need on-chain pool state with freshness indicators.

## Known failure modes

- Network timeout if Arc RPC is slow (tookMs may be very high)
- Stale data flag set to true if blockchain head is lagging
- Empty pools array if no active FUCI pools found
- Payment failure if 0.003 USDC x402 payment is not included or rejected
- HTTP 402 if payment header is missing or malformed

## How this service works

Free APEX on X1, and free USDC plus APEX on Arc, three times a day. No gas, no sign-up. Plus a swap, a screener, APEX City and token checks.

## Output

Returns a JSON object with an 'ok' boolean, a 'data' object containing fuci pool details (pool head block number, pools array, stale flag, counts object, method description, processing time in ms, burn proof, impostors map, and generated timestamp), and the 'paid' amount in USDC (0.003).
