## Facts

- Endpoint: POST https://bizintel-api.hahavoid0.workers.dev/finance/crypto-price
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/bizintel-api-crypto-price-lookup-coingecko-b307f068

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 bizintel-api-crypto-price-lookup-coingecko-b307f068 -d '<json body>'
```

Example prompt: What's the current price of Ethereum in USD? Use the CoinGecko slug 'ethereum' and quote it in usd.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call cryptocurrency price lookup using CoinGecko's index without managing API keys. It is ideal for agent workflows that need spot prices for one coin at a time, especially when already using the BizIntel API ecosystem for other data enrichment tasks. Prefer it over direct CoinGecko API calls when you need x402 USDC micropayment compatibility on Base.

## Known failure modes

- Invalid or unrecognized CoinGecko coin ID slug returns an error or supported:false
- Unsupported vs_currency may return a warning or empty result
- Network or worker timeout may return a 5xx error
- Coin delisted or unavailable from CoinGecko may reduce confidence or return no price

## How this service works

Fetches spot prices for token identifiers from the free CoinGecko simple price index.

## Output

Returns a JSON object with the coin's price in the requested currency (e.g. {ethereum: {usd: 3400}}), a confidence rating ('high'), a data_as_of timestamp (month-level), a supported flag, any warnings, and a disclaimer noting the data is informational only.
