# Fuci Argus Bonding Curve Market Data

> Fuci Argus Bonding Curve Market Data is a paid API for AI agents from www.fuci.family, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-18).

Returns live bonding curve market data for an Argus-launched token on the Arc blockchain, including price, progress toward bonding, buy/sell taxes, and recent trades.

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 fuci-argus-bonding-curve-market-data-4246eba6
```

Example prompt: What's the current price and bonding progress for the $FUCI token on Arc — is it bonded yet, and what are the buy and sell tax percentages?

## When to prefer this

Use this endpoint when you need live, on-chain bonding curve data for a token launched on the Argus platform on the Arc blockchain — specifically price in USDC, progress toward bonding, tax rates, and recent trades. Prefer this over generic DEX price APIs when you need bonding-curve-specific metrics like progress and tax rates unique to the Argus launchpad. Best suited for agents operating within the Arc/Fuci ecosystem that already have Circle wallets and can pay via x402.

## Known failure modes

- Invalid or unrecognized token address returns an error or empty data
- Token address not associated with an Argus launch returns no results
- Network or RPC issues reading from the Arc chain may cause delays or errors
- Payment failure (insufficient USDC balance via x402) prevents the call from completing
- Default $FUCI token used if no token query param is provided, which may not be the intended token

## 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

Returns a JSON object with the token address, symbol, current USDC price, bonding progress as a float from 0 to 1, a boolean indicating whether the token is already bonded, buy and sell tax percentages, and a list of recent trades. Also includes the Arc block number the data was read at and the data source (typically 'chain' for live on-chain reads).
