What Is a Provider

Each model on the platform may be backed by multiple providers. Providers are service nodes organized by source and cost — different providers have different pricing multipliers and model availability. When you send a request, the system automatically selects an available provider based on your token configuration. If a provider fails or times out, the system automatically retries another one — fully transparent to your code.

​
Available Providers

IDNameDescription
officialOfficialA provider group that aggregates direct connections to all major official platforms (OpenAI, Anthropic, Google, etc.); highest stability
official_cheapOfficial (Discounted)A cost-optimized version of official channels; high stability at a lower price
mixMixedMulti-source mixed channels; lowest price, widest model coverage

​
About official

official is a provider group that bundles nodes from OpenAI, Anthropic, Google, DeepSeek, and other major official platforms. When you select official, the system performs intelligent routing and failover across all official nodes — no need to specify each vendor individually.

​
Configuring Providers in a Token

When creating or editing a token, you can set the default routing behavior for that token.

​
Provider List

Specifies which providers this token is allowed to use.
  • Leave empty (recommended): Automatically routes across all available providers for best availability
  • Single provider: e.g. official — routes only through official nodes
  • Multiple providers: Comma-separated, e.g. official_cheap,mix — tried in order or by sort strategy

​
Provider-Only Mode

  • Off (default): Specified providers are prioritized; falls back to others if all fail
  • On: Strictly limited to the specified providers — if all fail, returns an error with no fallback

​
Sort Strategy

When multiple providers are specified, controls the order they are tried:
  • Manual (default): Tried in the order you listed them
  • Latency: Prioritizes the fastest-responding provider
  • Price: Prioritizes the lowest-cost provider
  • Throughput: Prioritizes the highest-throughput provider

​
Overriding Providers Per Request

You can also temporarily override token settings for a single request via headers — no token changes needed.
HeaderEffect
X-Provider-OrderSpecifies the providers and order for this request
X-Provider-Only"true" enables strict mode — no fallback
X-Provider-SortOverrides the sort strategy (latency / price / throughput)
X-Provider-IgnoreProviders to skip for this request, stacked on top of token config
Providers specified via headers are still subject to your account permissions.

Examples

Try discounted official first, fall back to mixed on failure 
curl https://api.ephone.ai/v1/chat/completions \
  -H "Authorization: Bearer sk-your-token" \
  -H "X-Provider-Order: official_cheap,mix" \
  -H "Content-Type: application/json" \
  -d '{"model": "gpt-4o", "messages": [{"role": "user", "content": "Hello"}]}'
Strict official-only, no fallback allowed 
curl https://api.ephone.ai/v1/chat/completions \
  -H "Authorization: Bearer sk-your-token" \
  -H "X-Provider-Order: official" \
  -H "X-Provider-Only: true" \
  -H "Content-Type: application/json" \
  -d '{"model": "claude-opus-4-5-20251101", "messages": [{"role": "user", "content": "Hello"}]}'
Set default headers in your SDK client 
import openai

client = openai.OpenAI(
    api_key="sk-your-token",
    base_url="https://api.ephone.ai/v1",
    default_headers={
        "X-Provider-Order": "official_cheap,mix",
    }
)
