HTTP 401

Missing, empty, or revoked API key. This response covers three distinct codes depending on the authentication path: - missing_api_key: Authorization header absent or Bearer token is empty. On GET /v1/models, GET /v1/models/{model}, GET /v1/me and GET /v1/me/avatar, which also accept the x-api-key header, the message is "Provide your API key as: Authorization: Bearer sk-devup-..., or in the x-api-key header." - invalid_api_key: Key not found, deactivated, or not valid. - token_revoked: The scoped JWT credential has been explicitly revoked.

HTTP 402

DZD balance depleted or scoped credential budget exhausted. - insufficient_balance: The DEVUP account has insufficient available balance. Also returned on POST /v1/chat/completions and POST /v1/responses for a request with a non-empty tools array that the balance does not cover in full. - budget_exhausted: The scoped credential has reached its configured budget. This code is never returned for unrestricted master API keys.

HTTP 404

The requested model identifier was not found in the catalog. It is not retryable unless the model identifier is changed.

application/json

ErrorResponse

    "message": "The requested model was not found.",
    "type": "devup_error",

HTTP 429

Too many requests. error.code is rate_limit_exceeded (your account's per-minute limit), model_at_capacity (the model is momentarily at capacity; Retry-After: 5 and retry-after-ms: 5000, no X-RateLimit-* headers; the OpenAI and Anthropic SDKs retry it automatically), concurrency_limit_exceeded, tpm_limit_exceeded, or flex_capacity_unavailable. Wait the number of seconds in Retry-After before retrying.

application/json

ErrorResponse

{
  "error": {
    "message": "Rate limit exceeded. Please slow down your requests and try again shortly.",
    "type": "devup_error",
    "code": "rate_limit_exceeded"
  }

{
  "error": {
    "message": "This model is currently at capacity. Retry in a few seconds.",
    "type": "devup_error",
    "code": "model_at_capacity"
  }
}

HTTP 502

The model could not complete the request this time. Retry the request. A request that the model rejects is never returned as 502: it returns 400 with a specific code, such as tools_not_supported, conversation_must_end_with_user, empty_message_content, feature_not_supported, response_format_not_supported or invalid_request_error. - DEVUP_COMPUTE_ERROR: The model returned an empty or unreadable response, or could not complete the request this time. - response_truncated: The response stream was cut off before completing.

ErrorResponse

{
  "error": {
    "message": "The model could not complete this request. Retry it; retrying usually succeeds.",

  }
}

{
  "error": {
