> BlockRun DeFiLlama 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 2026-09-14).

## 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-defillama-token-price-lookup-8d597345
```

Example prompt: What are the current prices of coingecko:treasure-magiccraft and coingecko:beam-2? Fetch them both in one call using the DeFiLlama price endpoint.

## When to prefer this

Use this endpoint when you need real-time token prices from DeFiLlama via CoinGecko slugs or on-chain ERC-20 contract addresses, especially for DeFi-native or long-tail tokens not easily found on centralized exchange APIs. Ideal for batch price lookups in a single paid call via x402/USDC micro-payment.

## Known failure modes

- Invalid or unrecognized coin identifier returns empty or error data
- Misspelled CoinGecko slug returns no price
- Contract address on wrong chain prefix returns null
- Network or gateway error returns non-200 status
- Exceeding query length for large comma-separated lists may fail silently

## 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 current USD price data for one or more tokens identified by CoinGecko slug or ERC-20 contract address (e.g. ethereum:0x...), delivered as a structured JSON object keyed by coin identifier.
