# BlockRun.AI Token Price Lookup

> BlockRun.AI Token Price Lookup is a paid API for AI agents from blockrun.ai, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-25).

Fetches current token prices by coin identifier (CoinGecko slug or contract address) via DefiLlama's price feed, supporting batch queries via comma-separated coin IDs.

## 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 blockrun-ai-token-price-lookup-c58d347a
```

Example prompt: Can you look up the current prices for wrapped bitcoin, WETH, and DAI using their CoinGecko IDs?

## When to prefer this

Choose this endpoint when you need fast, on-demand token price lookups across CoinGecko-listed tokens or EVM contract addresses, especially in batch. It's ideal for DeFi agents needing current prices without managing DefiLlama API keys directly, and pays per-call via x402 micropayment at $0.002 USDC, making it cost-effective for infrequent or automated price checks.

## Known failure modes

- Invalid or unrecognized coin identifier returns missing or empty data for that coin
- Malformed coin namespace (e.g. wrong prefix) causes no price returned
- Rate limiting or payment failure returns 402 or 429 error
- Requesting a very obscure token not indexed by DefiLlama returns null price
- Network timeout on batch requests with many tokens

## How this service works

Token price lookup. Pass coin identifiers as `/v1/defillama/prices/{coins}` (e.g. `coingecko:bitcoin`, `ethereum:0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2`). Supports comma-separated lists.

## Output

Returns a JSON object containing price data for each requested token, keyed by coin identifier, including current USD price and likely a timestamp — sourced from DefiLlama's aggregated price feed.
