How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

Output

A JSON object with a source attribution (DefiLlama) and an array of token objects, each containing: token ID (e.g. coingecko:ethereum), symbol, first recorded date (YYYY-MM-DD), first price in USD, current price in USD, percentage change since launch, and the price multiplier since launch.

Example use cases

Crypto portfolio inception ROI

“I hold BTC, ETH, and SOL — can you pull up when each of them first started trading, their initial prices, and how much they've multiplied in value since then?”

Altcoin early investor return check

“What was the very first price recorded for Chainlink (LINK) and what's the percentage gain from that launch price to today?”

DeFi token performance comparison

“Look up the launch prices for these DeFi tokens — UNI, AAVE, and CRV — and tell me which one has had the biggest percentage increase since it first started trading.”

When to prefer

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.

Side effects

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
