GET

/api/search

Searches domain, prefix, suffix, and recommendation flows through one public endpoint.

Parameters

`q` is required and holds the search input.
`type` supports `auto`, `domain`, `prefix`, `suffix`, and `recommendation`.
`mode`, `page`, `limit`, and repeated `tlds` further shape prefix and recommendation queries.

Response

`query`
`type`
`result` or streamed probe rows
`error` for controlled failures

Cache notes: Search responses are cached briefly for repeat queries, with special handling for streamed probe modes.

Example request: /api/search?q=example&type=domain

GET

/api/domain/[domain]

Returns a normalized domain availability and WHOIS summary for one domain name.

Parameters

`[domain]` path segment is required and should be a fully-qualified domain.

Response

`domain`
`is_available`
`query_method`
`status`
`name_servers`
`error_code` on controlled failures

Cache notes: Results are cached in-process to reduce duplicate upstream lookups.

Example request: /api/domain/example.com

GET

/api/whois/[domain]

Returns raw WHOIS text or controlled runtime failure details for one domain.

Parameters

`[domain]` path segment is required and should be a fully-qualified domain.

Response

`domain`
`raw_whois`
`query_method`
`transport`
`runtime_support_policy`
`error_code` when unavailable

Cache notes: This endpoint prefers the unified runtime query chain and falls back to third-party raw WHOIS when needed.

Example request: /api/whois/example.com

GET

/api/dns/[domain]

Fetches common DNS record families for a domain through Google Public DNS.

Parameters

`[domain]` path segment is required and should be a fully-qualified domain.

Response

`domain`
`provider`
`fetchedAt`
`records`
`error` on upstream failure

Cache notes: Successful responses are cached in memory without KV persistence.

Example request: /api/dns/example.com

GET

/api/ssl/[domain]

Returns the latest discovered certificate summary for a domain using crt.sh with a secondary fallback.

Parameters

`[domain]` path segment is required and should be a fully-qualified domain.

Response

`domain`
`provider`
`status`
`certificate`
`totalCertificates`
`error` on upstream failure

Cache notes: Successful responses are cached in memory without KV persistence.

Example request: /api/ssl/example.com

GET

/api/pricing

Returns current registrar pricing data used by TLD pricing surfaces.

Parameters

Query parameters depend on the requested pricing slice.
This endpoint is intended for the same public pricing data visible in the site UI.

Response

Pricing payload fields vary by query, but stay within the public registrar and TLD pricing domain.

Cache notes: Pricing responses are cached at the edge through shared API cache headers.

Example request: /api/pricing?tld=.com

GET

/api/tlds

Returns the public TLD data used by the TLD listing and search experiences.

Parameters

No required parameters.

Response

TLD listing data used by public browsing and search features.

Cache notes: TLD data is stable and can be cached more aggressively than live lookup endpoints.

Example request: /api/tlds

GET

/api/tld-list

Returns the public list of TLDs used by query and suggestion flows.

Parameters

No required parameters.

Response

TLD collection payload used by public query surfaces.

Cache notes: TLD list data is stable and suitable for edge caching.

Example request: /api/tld-list
