## 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 clinkagent-com-agent-service-history-tracker-e5fa071c
```

Example prompt: Pull the full historical record for the x402 listing at 'https://clinkagent.com/market/pulse' — I want to see its price changes, call volume, and paying customers day by day since it launched.

## When to prefer this

Choose this endpoint when you need longitudinal, day-by-day historical data on a specific x402 listing or MCP server — especially for competitive analysis, earnings benchmarking, or price-change audits. Prefer it over /market/pulse (which gives a market-wide overview) when your query is about one specific service's trajectory over time.

## Known failure modes

- Missing or invalid 'id' parameter returns an error; use /find to locate valid IDs
- Unknown or never-crawled listing ID returns empty history or not-found error
- Service not yet indexed in daily snapshots returns limited or no data
- Malformed x402 URL causes query failure; URL must be exact and URL-encoded

## How this service works

Track one agent service over time - the full day-by-day history of any x402 listing or MCP server: price changes, paying customers, call volume, installs, first and last seen. See what a listing like yours earns, watch a competitor grow or die. From daily whole-market snapshots the live catalogs don't keep. ?id=<x402 resource URL or MCP registry name> (find ids via /find, free). Market overview: /market/pulse $0.005.

## Output

A day-by-day historical timeline for the specified x402 resource or MCP server, covering price changes, call volume, paying customer counts, install totals, and first/last seen timestamps — sourced from daily whole-market snapshots not available in live catalogs.
