Price a batch
/v1/projects/{project}/plans/{plan}/access-codes/preview in the Access Codes API.
Prices a batch of quantity codes without queuing it, so a caller can show the worst-case charge before generating.
curl "https://api.subscriby.net/v1/projects/$PROJECT/plans/$PLAN/access-codes/preview?quantity=50" \ -H "Authorization: Bearer $SUBSCRIBY_TOKEN"Generation is free. The metered overage is billed at redemption time, and only when your tier's free access-code allotment is already exhausted. Hand out codes freely; you only pay for the ones subscribers actually activate beyond the free quota.
The preview and the bulk-generate endpoint both return this cost breakdown so callers can surface the worst case ("if every one of these codes is redeemed, here is what you would owe").
Requires ability
The token must hold this ability, or the call is refused with 403.
MCP tool
Runs the same action from an agent, behind the same ability.
Authorization
bearerToken A personal access token minted on the dashboard under Settings, then Tokens, sent as Authorization: Bearer sbt_live_…. The token carries the abilities each endpoint lists under Requires ability and is frozen to one team.

Responses
200OKapplication/json
The cost preview.
401UnauthorizedAUTHENTICATION_REQUIREDapplication/json
The request carries no bearer token, or one that is revoked, malformed, or minted for another environment (an sbt_test_ token on production).
403ForbiddenTOKEN_MISSING_ABILITYapplication/json
The token is valid but does not carry the ability this endpoint requires; error.context.required_ability names the one to grant. An endpoint that also checks who owns a row or which tier the account is on answers FORBIDDEN, TEAM_TIER_REQUIRED or CONNECTOR_TIER_REQUIRED with the same status, and says so in its own description.
404Not foundRESOURCE_NOT_FOUNDapplication/json
An id in the path names nothing the token can see. TENANT_MISMATCH: the project sits outside the token's scope:project: allow-list, or the token carries no team scope. Both answer 404 rather than 403 so that existence outside the token's scope cannot be inferred.
422Validation failedVALIDATION_FAILEDapplication/json
When quantity is missing or outside 1 to 1,000; error.context.quantity says so.
429Too many requestsRATE_LIMITEDapplication/json
The token has spent its 300 requests a minute or 10,000 an hour; Retry-After says when the next one is accepted.
