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 crypto-openverbs-com-historical-token-price-series-c4d9a931 -d '<json body>'
```

Example prompt: Can you pull me the daily historical USD prices for Bitcoin (coingecko:bitcoin) for the last 90 days so I can chart the trend?

## When to prefer this

Use this endpoint when you need a time-series of historical USD prices for a single token at a specific granularity (hourly, daily, or weekly) — ideal for charting, backtesting, trend analysis, or volatility calculations. Prefer this over the current-price endpoint when you need more than one data point. Choose coingecko:{slug} for well-known tokens and {chain}:{tokenAddress} for ERC-20 or other on-chain tokens not indexed by name.

## Known failure modes

- Unknown or invalid coin id returns an error (e.g. typo in coingecko slug or unrecognized chain:address)
- span out of range (must be 1–365) returns a validation error
- period value not in allowed enum ('1h','1d','1w') returns a validation error
- Token with insufficient historical data may return fewer points than requested
- Payment failure (x402) if USDC balance is insufficient
- Rate limiting or upstream data provider outage may cause transient 5xx errors

## How this service works

Historical USD price series for one token by coin id (e.g. "coingecko:bitcoin", "ethereum:0xdAC17…"). Returns evenly spaced `points` over the last `span` periods.

## Output

An array of evenly-spaced historical USD price data points for the requested token, covering the specified number of periods (up to 365) at the chosen granularity (hourly, daily, or weekly). Each point includes a timestamp and a USD price value.
