## 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 karma-domains-reports-by-domain-15e013f7
```

Example prompt: Pull the full Karma.Domains intelligence report for techstartup.io — I want to see its auction and buy-now listings, SEO authority metrics, Wayback history, and Karma Metric score.

## When to prefer this

Use this endpoint when you need comprehensive domain intelligence for a specific known domain — including market listings (auctions, expired, backorder, buy-now), SEO signals, authority metrics, historical Wayback data, and the Karma Metric score. Prefer this over search/filter endpoints when you already know the exact domain name and want a full multi-dimensional report on it.

## Known failure modes

- Missing required 'domain' query parameter returns 400 Bad Request
- Invalid or malformed domain string may return empty matches array
- HTTP 402 Payment Required when no valid API key or agent credits provided — retry with PAYMENT-SIGNATURE header
- HTTP 429 Too Many Requests when 60 req/min rate limit exceeded — check Retry-After header
- HTTP 503 when rate-limit storage is unavailable
- Daily row quota of 50,000 exhausted returns quota error with X-Quota-Reset header

## How this service works

Public API for Karma.Domains: programmatic access to domain intelligence — reports across auctions, expired, backorder, and buy-now inventories, SEO and authority metrics, Wayback history, availability checks, and Karma Metric. Use it to search, filter, and automate the same data workflows as the Karma.Domains web app.

**Authentication:** `Authorization: Bearer <api_key>` (Pro subscription or agent credits).
**Agent credits (x402):** HTTP 402 + `PAYMENT-REQUIRED` when unauthenticated; retry same URL with `PAYMENT-SIGNATURE` and optional `X-Karma-Plan-Id`.

**Rate limits:** 60 requests per minute per API key (all endpoints share one counter). Response headers: `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset`. On exceed: HTTP 429 with `Retry-After`. If rate-limit storage is unavailable: HTTP 503.

**Row quota:** 50,000 list rows per day per account (UTC reset). List responses include `X-Quota-Limit`, `X-Quota-Remaining`, `X-Quota-Reset`. Pagination: `page_size` 1–100 (Public API); `page × page_size ≤ 5000`.

## Output

A JSON object containing domain intelligence for the queried domain, including matches across auction, expired, backorder, and buy-now inventories, SEO and authority metrics, Wayback Machine history, availability status, and the proprietary Karma Metric score.
