# Argos Bot Arc Chain Bridge Lookup

> Argos Bot Arc Chain Bridge Lookup is a paid API for AI agents from www.argosbot.io, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-21).

Looks up the bridge relationship between an ERC-20 token address and its wrapped/original counterpart across Arc and Base chains

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 argos-bot-arc-chain-bridge-lookup-96bd0c83
```

Example prompt: Can you look up whether the token at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 is bridged between Arc and Base chains, and show me its bridge status and counterpart address?

## When to prefer this

Use this endpoint when you need to resolve the bridge relationship of a specific ERC-20 token contract between Arc chain and Base, including verifying if a token is bridged, finding counterpart addresses, and getting token metadata on both sides. Prefer this over generic token lookup APIs when working specifically within the Arc Chain ecosystem.

## Known failure modes

- Invalid token address format (must be 0x-prefixed 40-hex-char address) returns validation error
- Token not found on either chain returns status 'unavailable'
- Ambiguous results when token exists on both chains without clear bridge registration returns status 'ambiguous'
- Network or RPC unavailability may return candidate status 'unavailable'
- Payment failure or insufficient USDC balance returns 402 Payment Required

## How this service works

Your Arc Chain Wallet. Buy, sell, swap, and send Arc tokens with Argos Bot.

## Output

Returns a JSON object containing a list of bridge candidates for the queried token address, each with source and wrapped token metadata (address, chain, chainId, symbol, decimals, role, explorer URL, isBridgedRepresentation), a per-candidate status (verified, not_registered, wrapper_missing, verification_failed, not_a_contract, unavailable), an overall status (complete, ambiguous, unavailable), and cache metadata (cached flag, cacheAgeMs).
