# Base Token On-Chain Snapshot

> Base Token On-Chain Snapshot is a paid API for AI agents from dev.gavedu.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Returns metadata and recent transfer activity for an ERC-20 token contract on the Base blockchain.

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-token-on-chain-snapshot-f9b70b27
```

Example prompt: Pull the on-chain snapshot for the Base token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — I need its metadata and recent transfer activity.

## When to prefer this

Choose this endpoint when you need a quick, deterministic on-chain snapshot of a specific ERC-20 token on the Base network — combining metadata and recent transfer activity in a single call — without requiring API key signup. Ideal for DeFi agents, token research workflows, or any scenario where you have a Base contract address and need structured on-chain facts fast. Prefer this over general blockchain explorers when you want a machine-readable, pay-per-call result rather than a web UI.

## Known failure modes

- Invalid or malformed contract address (not 0x-prefixed or not 40 hex chars) returns an error
- Contract address that does not correspond to an ERC-20 token on Base may return empty or error response
- Network-level issues fetching on-chain data may cause timeouts or partial results
- Payment failure via x402 (insufficient USDC balance) prevents the call from completing

## How this service works

Deterministic Base token on-chain snapshot (metadata + recent transfer activity).

## Output

Returns a structured on-chain snapshot for the specified Base ERC-20 token contract, including token metadata (name, symbol, decimals, total supply, etc.) and a list of recent transfer events/activity on the Base network.
