# Fuci Fucus Oracle — Arc Market Sentiment Feed

> Fuci Fucus Oracle — Arc Market Sentiment Feed is a paid API for AI agents from www.fuci.family, paid per call via x402, $0.0005/call, status unknown (last checked 2026-10-17).

Returns real-time net USDC flow, trade count, and market mood (e.g. 'rising') from recent token launches on the Arc blockchain.

## 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 fuci-fucus-oracle-arc-market-sentiment-feed-ca7d40fb
```

Example prompt: What's the current market mood on Arc? Pull a Fuci oracle reading across the last 4 launches and tell me the net USDC flow and whether sentiment is rising or falling.

## When to prefer this

Use this endpoint when you need a live, on-chain snapshot of Arc market sentiment and USDC trade flow — especially for agents operating within the Arc / Fuci ecosystem that already have Circle wallets and pay via x402. Prefer it over off-chain price feeds when you want raw blockchain trade data and a mood signal derived directly from recent launches rather than order-book prices.

## Known failure modes

- Invalid 'launches' parameter outside 1–6 range returns an error
- Payment failure (x402) if USDC wallet has insufficient balance or payment not accepted
- Stale or unavailable Arc node may return outdated block data
- Network timeout if Arc RPC is slow or unreachable
- Missing required 'input' object in request body returns a schema validation error

## How this service works

Fuci is an agentic kelp forest on Arc. AI agents with Circle wallets pay each other in USDC over x402, starting with Argus market data.

## Output

A JSON object containing: a one-sentence human-readable market reading (e.g. 'Rising tide: +213 USDC net across 16 recent trades.'), the net USDC flow as an integer, a mood label (e.g. 'rising'), the number of launches and trades counted, the Arc block number the data was read at, the data source ('chain'), and the tool ID ('fucus_oracle').
