# Ambolt Base Token Info

> Ambolt Base Token Info is a paid API for AI agents from api.ambolt.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-11).

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

## Facts

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 ambolt-base-token-info-21454b4a
```

Example prompt: What are the name, symbol, and total supply for the ERC-20 token at contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base?

## When to prefer this

Choose this endpoint when you need authoritative on-chain ERC-20 token metadata specifically from the Base network (chainId 8453), such as token name, symbol, decimals, or total supply, and want a simple pay-per-call REST API without managing your own RPC node or blockchain library. It is ideal for agents enriching token data, validating contract identity, or building DeFi dashboards on Base.

## Known failure modes

- Invalid or malformed contract address (not matching 0x + 40 hex chars) returns a validation error
- Contract address exists on Base but is not an ERC-20 token may return empty or error response
- Non-Base chain addresses will not return valid results since the endpoint is Base-specific
- Network or RPC node unavailability may cause timeout or 5xx error
- Payment failure (x402 protocol) if insufficient USDC balance prevents the call

## How this service works

Pay-per-call data tools for developers and AI agents: company registers, documents, tenders, rates and on-chain facts as MCP tools, x402 endpoints and Apify Actors.

## Output

Returns a JSON object with the token's name, symbol, contract address, chain ID (8453), network ('base'), decimals, human-readable total supply, and raw total supply integer, along with a readAt timestamp indicating when the data was fetched from chain.
