# Tanod agentscan: agent-index history lookup

> Tanod agentscan: agent-index history lookup is a paid API for AI agents from tanod.dev, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-12).

Retrieves the historical record(s) for a specific endpoint or resource in the Tanod agentscan agent-economy index, including price history and first/last-seen dates.

## Facts

- Endpoint: POST https://tanod.dev/v1/agents/history?utm_source=zero.xyz
- Price: $0.05/call
- Payment: x402

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 tanod-agentscan-agent-index-history-lookup-2f9b9ab3 -d '<json body>'
```

Example prompt: Can you pull up the full price history for the agentscan record with source 'cdp_bazaar' and ID 'resource-123' — I want to see when it was first listed and how the price has changed?

## When to prefer this

Use this endpoint when you need historical data — price changes, first/last seen dates — for a specific known record in the Tanod agentscan index. If you need to search or filter across many records by category or source without a known ID or URL, prefer the agentscan query endpoint instead.

## Known failure modes

- No matching record found if the provided ID, source, or URL does not exist in the index — returns count 0 and empty records array
- Invalid or missing parameters may return an error or empty result
- Record may not be found if the URL is not an exact match (case-sensitive, trailing slashes matter)
- Price or history data may be incomplete if the endpoint was only recently indexed

## How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

## Output

Returns a JSON object with a count and an array of records, each containing the endpoint's ID, URL, name, source, category, first_seen date, last_seen date, current price in USD, and a full price_changes history array showing date and price for each change.
