# Base Scout Token Metadata

> Base Scout Token Metadata is a paid API for AI agents from base-scout.botty4541.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-16).

Looks up ERC-20 token metadata on the Base chain by contract address, returning name, symbol, decimals, and total supply.

## Facts

- Endpoint: GET https://base-scout.botty4541.workers.dev/service/token
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-16

- Tags: x402
- Canonical page: https://www.zero.xyz/c/base-scout-token-metadata-ad3cfd19
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_9SPfn6NP4eRGF2wA5DcnR

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 base-scout-token-metadata-ad3cfd19
```

Example prompt: What ERC-20 token is deployed at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — what's its name, symbol, and how many decimals does it use?

## When to prefer this

Choose this endpoint when you need on-chain ERC-20 token metadata (name, symbol, decimals, total supply) specifically on the Base network, and you need it in a pay-per-call model without an API key subscription. Ideal for AI agents that need lightweight, on-demand token resolution on Base without maintaining a persistent blockchain connection.

## Known failure modes

- Invalid or non-ERC-20 contract address returns an error or ok:false
- Address of a non-token contract (e.g. EOA or non-standard contract) may return empty or error
- Network congestion on Base RPC may cause delays or timeouts
- Malformed 0x address format will fail input validation
- Payment failure via x402 prevents the call from completing

## How this service works

Pay-per-call Base chain utilities for AI agents and bots: tx status, wallet balances, token metadata, prices. 0.01 USDC per call on Base (x402). Price: 0.01 USDC per call on Base (x402).

## Output

Returns a JSON object with ok (boolean), data containing the token's name, symbol, contract address, decimals (integer), and totalSupply (string), plus payer address and transaction hash confirming the micropayment.
