All endpoints share the same base: 
https://llm.bytespike.ai
  • https://llm.bytespike.ai/v1/* — Anthropic + OpenAI surfaces
  • https://llm.bytespike.ai/v1beta/* — Gemini Native surface
  • https://llm.bytespike.ai/api/v1/* — management endpoints (keys, usage, billing)
Auth is a single header (see Authentication). Failures don’t bill. Every response carries quota + rate-limit headers so you don’t need a side channel for accounting.

Live pricing

Per-token / per-call rates come from the production gateway and refresh nightly. The authoritative table lives at bytespike.ai/pricing — link directly to the section you need:

Conventions

Async vs sync. Text endpoints are synchronous. Image is synchronous (≤30s for single-image, large batches may use the async tasks API). Video is async — POST /v1/tasks/submit returns a task_id, poll /v1/tasks/query (free) or stream /v1/tasks/stream/{task_id} via SSE. The tasks reference covers the full lifecycle. Streaming. Pass "stream": true (or ?stream=true on Gemini). The SSE stream is byte-for-byte compatible with each protocol’s native streaming format — Anthropic event names on /v1/messages, OpenAI event names on /v1/chat/completions and /v1/responses, Gemini’s chunked streamGenerateContent on /v1beta. Accounting headers. Every response (success and failure) carries the gateway’s quota envelope:
HeaderWhat it means
X-RateLimit-LimitUSD cap of the rate-limit bucket closest to constraining you.
X-RateLimit-RemainingBudget left in that bucket.
X-RateLimit-ResetBucket reset Unix timestamp.
X-Quota-Remaining-CreditsLifetime credits remaining on this key (USD; 1 USD = 1M credits).
X-Org-Quota-Remaining-CreditsSame, at the org wallet level, on org-owned keys.
For per-request cost, query GET /api/v1/usage — it returns one row per request with prompt_tokens, completion_tokens, and billed credits. Non-2xx responses don’t bill, so X-Quota-Remaining-Credits doesn’t move on a failure.
