# Find Domain

Pay-per-query domain research API. Domain name suggestions and availability
checks for $0.005–$0.020 USDC per query, settled on Base via the x402
protocol. No API keys, no accounts, no rate limits — payment is
authentication.

**Base URL:** `https://finddomain.io`

## Endpoints

| Endpoint | Price | Description |
|----------|-------|-------------|
| `GET /suggest?query=TERM` | $0.005 | Algorithmic domain name suggestions (stemming, IDN normalization, alternatives) |
| `GET /status?domain=DOMAIN` | $0.020 | Precise registry-level availability check — definitive answer |
| `GET /status?domain=DOMAIN&scope=estimate` | $0.005 | Estimated availability via DNS — fast, no registry lookup |
| `GET /demo?query=TERM` | Free | Limited demo: 5 alphabetized suggestions, 3 queries/day per IP |
| `POST /scout` | $0.15 / $0.50 | Research job: ranked, evidence-backed shortlist from a naming brief; amount paid selects the tier |
| `GET /scout/JOB_ID` | Free | Poll a Scout job |

## How it works

1. Call any paid endpoint with no credentials.
2. Receive `402 Payment Required` with x402 v2 payment requirements
   (USDC on Base, `eip155:8453`).
3. Retry with a signed payment authorization. x402 client SDKs
   (Node.js, Python) handle this automatically.
