API REFERENCE

Universal parameters

Headers, auth schemes, error envelopes and conventions that apply across every endpoint.

Authentication

All endpoints require an Airforce API key. Generate one in the dashboard under API Keys. Keys begin with sk-air-.

Parameter	Type	Required	Description
Authorization	string	Required	Bearer sk-air-YOUR_API_KEY. Accepted on every endpoint.
x-api-key	string	Optional	Alternative auth header. Accepted on /v1/messages and /v1/responses for Anthropic SDK compatibility.
anthropic-version	string	Optional	Required when using /v1/messages with the @anthropic-ai/sdk. Use "2023-06-01".
Content-Type	string	Optional	application/json for body posts. multipart/form-data for endpoints that accept file uploads (transcriptions, voice cloning, etc.).

Examples

# Standard
curl https://api.airforce/v1/chat/completions \
  -H "Authorization: Bearer sk-air-YOUR_API_KEY" \
  …

# Anthropic SDK style (only on /v1/messages, /v1/responses)
curl https://api.airforce/v1/messages \
  -H "x-api-key: sk-air-YOUR_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
  …

# Multipart upload (file endpoints)
curl https://api.airforce/v1/audio/transcriptions \
  -H "Authorization: Bearer sk-air-YOUR_API_KEY" \
  -F "[email protected]" \
  -F "model=whisper-1"

Optional request headers

Parameter	Type	Required	Description
X-Request-ID	string	Optional	Echoed in the response. Send your own correlation ID and we forward it through to logs and intercept records.
User-Agent	string	Optional	Helpful for debugging. Logged with every request.

Response headers

Parameter	Type	Required	Description
X-Request-ID	string	Optional	Server-generated request ID. Quote this when filing a support ticket.
X-Cost-Cents	integer	Optional	Cost of the request in cents (4 decimals of precision). Present on completed billing-relevant calls.
X-Tokens-Prompt / X-Tokens-Completion	integer	Optional	Token counts for chat / messages calls.
X-Cache-Hit	string	Optional	"5m" / "1h" / "miss" on Anthropic-style cached calls.

Reasoning & thinking (cross-endpoint)

Models with supports_reasoning: true accept the same canonical parameters everywhere they appear (currently /v1/chat/completions and /v1/messages).

Parameter	Type	Required	Description
reasoning_effort	string	Optional	"low" \| "medium" \| "high". OpenAI o-series / GPT-5 reasoning models only — has no effect on Claude. Use `thinking_budget` for Anthropic budget control.
thinking	string \| object	Optional	"on" / "off" / "auto" for a quick toggle, or { type: "enabled", budget_tokens: N } Anthropic shape. Both forms accepted, both normalised to the upstream's native shape.
thinking_budget	integer	Optional	Maximum tokens spent reasoning before visible output starts. Maps to budget_tokens (Anthropic) and thinking_budget (Gemini).
ignore_defaults	boolean	Optional	Bypass your saved per-model defaults for this single request. Useful when a saved default (e.g. thinking on) is overriding the value you sent.

Streaming convention

Endpoints that accept stream: true respond with Content-Type: text/event-stream and emit Server-Sent Events. The wire format depends on the endpoint:

Parameter	Type	Required	Description
/v1/chat/completions	OpenAI SSE	Optional	data: {…JSON chunk…}, terminated by data: [DONE].
/v1/messages	Anthropic SSE	Optional	Named events: message_start, content_block_start, content_block_delta, content_block_stop, message_delta, message_stop.
/v1/images/generations (sse: true)	OpenAI-shape SSE	Optional	Single data: event with the full response, then [DONE]. Useful for long-running image jobs to keep the connection alive.
/v1/video/tasks/:id/stream	progress SSE	Optional	Periodic { progress, status } events for in-flight video tasks. Stream closes once the task is done.

Error envelope

Every error response uses the same JSON shape. The HTTP status code reflects the failure class.

Parameter	Type	Required	Description
error.message	string	Optional	Human-readable message safe to display.
error.type	string	Optional	Machine-readable category. See table below.
error.code	string	Optional	Specific identifier when applicable, e.g. "model_not_found".
error.param	string	Optional	Field name that failed validation, when relevant.

Parameter	Type	Required	Description
400	invalid_request	Optional	Malformed JSON, unknown field, validation failed.
401	authentication_error	Optional	Missing or invalid API key.
403	permission_error	Optional	Plan or per-key restriction blocks this request.
404	not_found	Optional	Unknown resource (model, task ID, voice ID).
413	payload_too_large	Optional	Upload exceeds size limit (200 MB for voice samples, etc.).
429	rate_limit	Optional	Per-second throttle, daily token cap, or balance exhausted.
500	internal_error	Optional	Unexpected. Quote the X-Request-ID when reporting.
503	upstream_error	Optional	Every key for the requested provider is failing right now. Retry with a different model or wait.

{
  "error": {
    "message": "Model 'gpt-99' not found.",
    "type": "invalid_request",
    "param": "model",
    "code": "model_not_found"
  }
}

Rate limits & retries

Limits are enforced per API key. Exceeding any of them returns 429:

Per-second request throttle (plan-dependent).
Daily token cap on free / pay-as-you-go plans.
Per-key credit allowance when you set one in the dashboard.
Concurrent video tasks (typically 4 in flight).

Retry with exponential backoff on 429 and 503. Don't retry on 4xx other than 429.

Idempotency

Generation endpoints (chat, image, audio, video) are not idempotent — each call produces a fresh response and is billed independently. For deterministic results, set a fixed seed where supported (image / audio / some chat models). Long-running async endpoints (/v1/video/generations) return a task_id you can re-poll safely.
