# Token Launch Price & Performance

> Token Launch Price & Performance is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-29).

Returns the first recorded price and launch date of one or more crypto tokens, plus current price, percentage change, and multiplier since launch, sourced from DefiLlama.

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 token-launch-price-performance-4cd9c9c5 -d '<json body>'
```

Example prompt: What was the first recorded price of ETH and SOL, when did they start trading, and how much have they gone up since then as a multiple and percentage?

## When to prefer this

Choose this endpoint when you need historical inception price data and ROI metrics (multiplier, % change) for crypto tokens, especially when you want DefiLlama-sourced data. It supports both ticker symbols (BTC, ETH) and chain:contract identifiers, making it flexible for both major coins and long-tail DeFi tokens. Prefer it over generic price APIs when the specific query is about launch/inception performance rather than current price only.

## Known failure modes

- Unknown token symbol or contract ID returns null or empty entry for that token
- Invalid chain:contract format causes parsing error or null result
- Token with no DefiLlama price history returns null fields
- Network or upstream DefiLlama API unavailability causes request failure
- Malformed coins input string (e.g. wrong delimiter) may return empty results
