# 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 2026-09-15).

## 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-1a4a3c07
```

Example prompt: Can you look up the current prices of bitcoin, ethereum, and USDC for me using their coingecko identifiers?

## When to prefer this

Use this endpoint when you need real-time or near-real-time token prices for one or more cryptocurrencies identified by CoinGecko slug or EVM contract address. Prefer this over general web search when you need structured, machine-readable price data ready for computation. Especially useful for DeFi portfolio valuation, stablecoin peg checks, or any workflow requiring programmatic token price ingestion.

## Known failure modes

- Invalid or unrecognized coin identifier returns an empty or error result for that coin
- Malformed coingecko slug causes lookup failure
- Network or upstream DefiLlama unavailability results in a 5xx error
- Requesting too many coins in one call may hit URL length or rate limits
- Payment failure (x402) blocks the call before it reaches the pricing service

## 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 price object keyed by coin identifier, containing the current USD price (and possibly timestamp or confidence) for each requested token. Supports batch responses for comma-separated coin lists.
