# certificate-history-bulk

> certificate-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).

Bulk-fetch certificate transparency log history for up to 20 domains in a single concurrent call, returning per-domain SSL/TLS issuance records with per-item error reporting.

## Facts

- Endpoint: GET https://intel.rallylive.ca/bulk/monitor/cert-history
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/certificate-history-bulk-5c9ebaae
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_uNjhdGrpe4Xkx1OWVv2u4

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 certificate-history-bulk-5c9ebaae
```

Example prompt: Can you pull the full certificate transparency history for these 15 domains — example.com, acme.org, store.acme.org, and the rest in my list — and flag any failures per domain?

## When to prefer this

Choose this endpoint when you have a list of 2–20 domains and need certificate transparency history for all of them, instead of making repeated single-domain calls. It processes all domains concurrently and returns results in input order with per-item error handling, making it ideal for batch enrichment pipelines, security audits, and domain fleet monitoring. Use the single /monitor/cert-history endpoint instead for a single domain.

## Known failure modes

- Individual domain lookup failures surfaced via per-item error field rather than a whole-call error
- Input exceeds 20-domain limit may cause rejection or truncation
- Malformed domain names result in per-item errors
- CT log data may be incomplete or delayed for very recently issued certificates
- Network timeouts on concurrent upstream CT log queries may increase per-item failures

## How this service works

Bulk certificate history: up to 20 domains 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 /monitor/cert-history endpoint (Certificate issuance history from certificate-transparency logs). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered array of results matching the input domain list. Each item contains the same certificate issuance history data as the single-domain cert-history endpoint (certificates from CT logs, issuance dates, CAs, SANs, etc.), plus a per-item error field if that domain's lookup failed. A top-level failure count is also returned.
