}Requires the IAM action
loadbalancer:CreateLoadBalancer. See LOADBALANCER permissions for the full list, what each one covers, and an example policy.Authorizations
An OAuth 2.0 bearer token, sent as Authorization: Bearer <token>.
This is the recommended way to authenticate.
Get one by exchanging a service account's access key pair at
POST /v1/oauth/token with grant_type=client_credentials. It is the
standard client-credentials grant, so any OAuth-aware library will
obtain and refresh it for you.
curl -s -u "$KEY_ID:$SECRET" -d grant_type=client_credentials \
https://iam.basaltic.sh/v1/oauth/token
Tokens last an hour by default. The same access key pair is separately your AWS SigV4 credential for the S3-compatible object endpoint, which speaks nothing else.
Headers
Optional client-generated key that makes a create replay-safe. Retrying a request with the same key returns the original outcome verbatim instead of creating a duplicate resource. Reusing a key with a different request body is rejected (422); a request whose key is still being processed returns 409. Records are honored for 24 hours. Use a UUID or similarly unique token.
Maximum string length:
255Body
application/json
Relationships accept a UUID, CRN or exact immutable name, classified by syntax. VPC, subnets and security groups must belong to the caller account in this region. Subnet names are scoped by vpc. Flavor is a regional catalog reference. Floating IP references accept UUID or CRN only. All references resolve before writes. Addresses are fixed at creation; updates cannot replace them.
1..127 chars of [A-Za-z0-9._-] Resource names must not start with the literal crn: prefix or be UUIDs (canonical, compact, braced, or urn:uuid: forms, in either case).
Example:
"web-lb"
Available options:
application, network Example:
"application"
VPC the LB will live in. Every selected subnet must belong to this VPC.
Example:
"c3d4e5f6-a7b8-4901-c2d3-e4f5a6b7c8d9"
One or more subnet selectors in the same VPC, account and region. Each instance has one interface; new instances are placed in the least-populated eligible subnet. The first subnet supplies automatic private floating IP allocations. Placement is fixed at creation.

["d4e5f6a7-b8c9-4012-d3e4-f5a6b7c8d9e0"]
Compute flavor for each LB instance.
Example:
"e5f6a7b8-c9d0-4123-e4f5-a6b7c8d9e0f1"
Security groups attached to every replica NIC (AWS ALB shape). A VPC NIC with no security group denies all data traffic, so the listener port(s) must be opened by a security group listed here. Re-applied to replacement replicas. The LB's own control-plane path (agent config + heartbeat via the metadata endpoint) is always-allowed and needs none.

["d1b6f3a8-4c2e-4a9d-8f7b-1e5c3a2d9b4f"]

Target tracking shared by instance pools and load balancers. Updates replace the policy. Set enabled=false to retain settings and use manual sizing. Each metric recommends a desired count; the largest recommendation wins. Missing, stale or incomplete observations prevent scale-in but do not block scale-out recommended by another valid metric. Decisions obey the resource's min_count/max_count, warmup, cooldown, stabilization, step limits and quotas. State survives controller restarts. Active policies own desired_count; manual changes are accepted and automatic evaluation resumes after cooldown. Custom telemetry requires telemetry:ReadMetrics in the same account.

Deprecated input alias of desired_count; send only one. Desired defaults to 1. Omitted bounds default to desired.
Required range:
1 <= x <= 10Example:
2
Existing free floating IPs from this account and region, at most one per family and visibility (private/public, IPv4/IPv6). Private addresses must belong to any selected subnet. Missing private families are allocated automatically from the first selected subnet for each family enabled there. Public addresses are optional and require a matching-family default route to an internet gateway in every selected subnet; NAT and egress-only gateways do not qualify. Public IPv6 requires every selected subnet to support IPv6. Pool-owned or attached addresses are unavailable. On deletion, supplied addresses are detached and retained; automatic private allocations are released.
