# Token Age

> Token Age is a paid API for AI agents from 402.com.tr, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Returns the age of a Base token by finding its earliest on-chain transfer, expressed in days and categorized as brand_new, very_new, new, established, or mature.

## 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 token-age-dbb19299
```

Example prompt: How old is the Base token at 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed — when did it first transfer on-chain, how many days ago is that, and is it brand_new, very_new, new, established, or mature?

## When to prefer this

Use this endpoint when you need a fast, cheap ($0.01 USDC) first-order risk signal about how long a Base token has been trading. Prefer it as an early filter in any token due-diligence pipeline — before deeper analysis like rug probability or holder distribution — especially when evaluating newly listed or unfamiliar tokens. Pairs naturally with Token Momentum, Rug Probability Score, and Token Holder Distribution for a fuller risk picture.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Token with no transfer history on Base cannot be aged
- Network latency or RPC issues may cause timeouts
- Non-Base-chain addresses will not return valid data
- Payment failure (insufficient USDC) blocks the call

## How this service works

When was this token born — its earliest transfer on Base — and how old is it in days, with a verdict: brand_new (<1d), very_new (<7d, where most rugs happen), new (<30d), established, or mature. New is not bad, but age is a first-order risk input every agent should have before sizing. Pairs with launch-snipers and token-risk. Not a safety verdict on its own. Not financial advice.

## Output

Returns the token's earliest transfer timestamp on Base, its age in days, and a categorical verdict (brand_new = <1d, very_new = <7d, new = <30d, established, or mature), which agents can use as a first-order risk input before sizing a position.
