Why developer API demand is evergreen

Agents, IDE copilots, and automation will keep needing chat completions. The durable question is which backend sees those prompts — and whether that backend trains on them or meters them honestly.

OpenAI-compatible shapes persist because SDKs and tools standardized on them. A private endpoint that speaks the same dialect wins migrations.

Cipher basics

Base URL: https://secrypt.space/v1. Model id: cipher (alias secrypt-cloud). Auth: Bearer sk_sec_… from Account → API keys.

Call POST /v1/chat/completions like any OpenAI-shaped client. Docs live at /docs; product overview at /api.

Pro2,000$0.01 / request credits
Unlimited10,000$0.01 / request credits

Chat meters ≠ API meters

Secrypt separates chat UI quotas from API key quotas. Cursor can burn API allowance while your browser chat still has messages left — and the reverse.

Chat overage is $0.05/message via credits. API overage is $0.01/request. Buy credits from Account when agents are busy.

IDE and agent wiring

Point Cursor, Continue.dev, or VS Code OpenAI-compatible backends at Secrypt’s base URL with your key. Prefer short system prompts and redact secrets in tool outputs.

Revoke keys when a laptop is lost. Rotate keys per environment (dev vs prod).

  • Never commit sk_sec keys to git
  • Use separate keys per machine or CI job
  • Watch Account usage for chat vs API
  • Read /blog/use-secrypt-in-cursor for a cookbook

Local LLM vs private hosted API

Local wins when air-gapping is mandatory. Private hosted API wins when you want less ops and still care about no-training posture. Many teams use both: local for sealed code, Secrypt Cipher for everyday agent work.

Frequently asked questions

Is Cipher the same as ChatGPT’s API?

It is OpenAI-compatible in request shape. It is Secrypt’s private Cipher model path with Secrypt privacy and pricing — not OpenAI.

Do API calls train Secrypt models on my prompts?

Secrypt’s product posture excludes conversation content from model training and ad profiling. Read /privacy for the full policy.

What model id should I send?

Prefer cipher. secrypt-cloud is an alias.

How do I start?

Create an account, mint a sk_sec key, set base URL to https://secrypt.space/v1, and run a tiny chat completions smoke test.

Is there unlimited free API?

No. Free includes 50 API requests/day, then pay-as-you-go credits. Paid plans raise the daily allowance.
