A zone with no existing zone above it on the platform does not resolve until `verified` is true — publish the TXT record below at your current DNS provider, then POST /v1/zones/{zone_id}/verify-ownership. If the domain is already delegated to us there is nowhere to publish that TXT, because we are its current DNS and an unverified zone does not answer. Use `claim_nameservers` instead. A zone created underneath a zone you already own inherits its parent's proof and is verified on creation. The proof is a lease, not a deed: it is re-confirmed periodically for as long as the zone is served, so a domain that lapses or changes hands stops being served from here. `checked_at` is the last confirmation; `recheck_deadline` appears only while re-confirmation is failing and is the field to render a warning from. properties: verified: type: boolean readOnly: true description: >- Whether the zone has proved ownership. Unverified zones do not resolve. example: false verified_at: type: string format: date-time readOnly: true nullable: true description: When ownership was first proved. Absent while unverified. example: '2026-01-15T09:30:00Z' checked_at: type: string format: date-time readOnly: true description: > When the proof was last re-confirmed. `verified_at` keeps meaning "first demonstrated" and does not move; this does, on every pass that passes. Absent until the zone has been re-confirmed at least once. example: '2026-04-14T09:30:00Z' recheck_deadline: type: string format: date-time readOnly: true description: > Present ONLY while the periodic re-proof is failing: the instant the zone stops answering unless it passes again. Absent means healthy. Each pass re-checks a failing zone, so reaching this date takes sustained failure, not one bad afternoon — a transient resolver problem clears itself on the next pass. To clear it deliberately, republish the challenge TXT (or point the domain's delegation back at our nameservers) and POST /v1/zones/{zone_id}/verify-ownership. The organization's owner is emailed when this date is set, and again if the zone does stop resolving. A zone is never taken off the air before that message has gone out, so the date here is the earliest the zone can stop answering and never the only warning. example: '2026-04-28T09:30:00Z' record_type: type: string readOnly: true example: TXT record_name: type: string readOnly: true description: Owner name the challenge TXT must be published at. example: _basaltic-challenge.example.com record_value: type: string readOnly: true description: Value the challenge TXT must contain. example: 9f2c1e7a4b8d6035e1a4c9f27b0d8e63a5f1c4b90d2e7a836f5c1b904e7d2a68 claim_nameservers: type: array readOnly: true description: > The other way to prove ownership: set these as the domain's nameservers at your registrar, then POST /v1/zones/{zone_id}/verify-ownership. This is the route for a domain already delegated to us, where the challenge TXT can never resolve. These names reach the same servers the zone's `nameservers` do, but they are unique to this zone, and that is what makes them proof. Anyone can point a domain at our published nameservers, so a delegation naming those shows only that somebody did so at some point — possibly a previous owner who never updated their registrar. A delegation naming these can only have been set for this zone, by whoever holds the domain now. The delegation may stay on these names permanently. items: type: string example: - ns1.9f2c1e7a4b8d6035.claim.dns.basaltic.cloud - ns2.9f2c1e7a4b8d6035.claim.dns.basaltic.cloud ZoneDSRecord: type: object description: One DS record to publish at the parent zone. required: - key_tag - algorithm - digest_type - digest - rdata properties: key_tag: type: integer example: 12345 algorithm: type: integer example: 13 digest_type: type: integer description: 2 = SHA-256. example: 2 digest: type: string example: B8FA03AA1BB49CC702C32C5C3FE6061BBDD0808371F43A28A8E8BE2738CC9861 rdata: type: string description: >- Full zone-file form — ` `. example: >- 12345 13 2 B8FA03AA1BB49CC702C32C5C3FE6061BBDD0808371F43A28A8E8BE2738CC9861 responses: Unauthorized: description: Authentication required or token invalid content: application/json: schema: $ref: '#/components/schemas/Error' example: error: code: UNAUTHORIZED message: Authentication required request_id: 550e8400-e29b-41d4-a716-446655440000 Forbidden: description: Insufficient permissions content: application/json: schema: $ref: '#/components/schemas/Error' example: error: code: ACCESS_DENIED message: You don't have permission to perform this action request_id: 550e8400-e29b-41d4-a716-446655440000 InternalServerError: description: Internal server error content: application/json: schema: $ref: '#/components/schemas/Error' example: error: code: INTERNAL_ERROR message: An internal error occurred request_id: 550e8400-e29b-41d4-a716-446655440000 securitySchemes: SignatureAuth: type: apiKey in: header name: Authorization description: > Request signing with an access key issued to a service account. An HMAC-SHA256 over a canonical form of the request, close to AWS SigV4. The `basaltic` CLI signs for you. Send `Authorization`, `X-Date` (UTC, `YYYYMMDDTHHMMSSZ`) and `X-Nonce` (random per request); add `X-Content-Sha256` to bind a body, and `X-Amz-Security-Token` when using temporary credentials. ``` Authorization: BASALTIC-HMAC-SHA256 Credential=///basaltic/basaltic_request, SignedHeaders=host;x-date;x-nonce, Signature= ``` `` is the region code you are calling, or `global` for the global services. A signature is valid for 5 minutes from `X-Date`, and mutating requests are replay-guarded on the nonce. **Full signing procedure, including a working implementation:** https://docs.basaltic.sh/authentication ## Rate limits There is no global request budget. A limit applies only where an operation documents a `429`, and that operation says what it counts. Those responses carry `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset` and, on a `429`, `Retry-After` — read them rather than hard-coding a number. Retrying before `Retry-After` is refused and extends the window. Everything else is bounded by quota, not by request rate. ````
