# URL Uptime History Bulk

> URL Uptime History Bulk is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Fetches uptime/status history for up to 20 URLs in a single concurrent batch, returning results in input order with per-item error fields and a failure count.

## 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 url-uptime-history-bulk-db6c2b5b
```

Example prompt: Can you pull the uptime history for these 15 websites all at once and tell me which ones have had downtime recently: site1.com, site2.com, site3.com, site4.com, site5.com, site6.com, site7.com, site8.com, site9.com, site10.com, site11.com, site12.com, site13.com, site14.com, site15.com?

## When to prefer this

Choose this endpoint when you have a list of 2–20 URLs and need uptime history for all of them efficiently — it runs concurrent lookups and returns results in input order, avoiding the overhead of sequential single-URL calls. Prefer it over the single /site/status-history endpoint whenever you hold a batch of URLs to check.

## Known failure modes

- More than 20 URLs submitted — batch limit exceeded
- One or more URLs malformed — per-item error field populated for those entries
- Target URL unreachable or returns no history — per-item error with empty history
- Payment not completed — x402 payment required error
- Network timeout on concurrent fetches — some items may carry errors while others succeed

## How this service works

Bulk url uptime history: up to 20 urls in one call, processed concurrently, results returned in input order with a per-item error field and a count of failures. Same answer per item as the single /site/status-history endpoint (URL uptime history). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered array of uptime/status history results matching the input URL order, where each item mirrors the single /site/status-history response and includes a per-item error field if that URL failed. A top-level count of failures across the batch is also returned.
