What you get#
Onekey exposes DNS as 7 endpoints behind one API key: 7 endpoints return a list (data is an array). Every answer uses the same envelope (success, data, metadata, error), the cost is reported in metadata.credits_charged, and fields are mapped onto the unified schema so the code you write for DNS also works for the rest of the web tools category.
Endpoints#
| Endpoint | What it does | Parameters | Credits | Status |
|---|---|---|---|---|
a | DNS IPv4 addresses (A) of a name via DNS-over-HTTPS (Cloudflare, Google fallback). | name* | 1 | stable |
aaaa | DNS IPv6 addresses (AAAA) of a name via DNS-over-HTTPS (Cloudflare, Google fallback). | name* | 1 | stable |
cname | DNS canonical name (CNAME) of a name via DNS-over-HTTPS (Cloudflare, Google fallback). | name* | 1 | stable |
lookup | Generic DNS lookup for any common record type via DNS-over-HTTPS. | name*, type | 1 | stable |
mx | DNS mail exchangers (MX) of a name via DNS-over-HTTPS (Cloudflare, Google fallback). | name* | 1 | stable |
ns | DNS name servers (NS) of a name via DNS-over-HTTPS (Cloudflare, Google fallback). | name* | 1 | stable |
txt | DNS TXT records (SPF, DKIM, verification) of a name via DNS-over-HTTPS (Cloudflare, Google fallback). | name* | 1 | stable |
A * marks a required parameter. Each endpoint name links to its reference page with the full parameter table, caching window and a recorded response.
Make a request#
This calls dns.a (1 credit, stable). Replace YOUR_API_KEY with your key; sign up, no card. 1,000 free credits cover the open-platform endpoints. Hard-to-reach platforms (X, TikTok, Instagram, Reddit, and others marked on their page) need a verified email and a purchased pack.
curl "https://api.onekey.dev/v1/dns/a?name=example.com" \
-H "x-api-key: YOUR_API_KEY"Fields you get back#
These unified fields come back from DNS, with the same names as on every other platform. The count is how many of its 7 mapped endpoints return the field; a field the source lacks is null, never missing. 2 platform-specific fields (ext.<name>) come on top, documented on each endpoint page.
| Field | Type | Endpoints |
|---|---|---|
entity.name | string | 7 |
entity.type | string | 7 |
The full schema is in Unified schema.
Pricing#
Every DNS endpoint costs 1 credit per call. Free when served from cache (0.2 credit for a cached response over 100 KB). Invalid, failed or not-found calls are not charged. See pricing for credit packs.
