Endpoints

Call shared models immediately or reserve dedicated capacity. Morph manages both.

Choose how to serve

	Shared inference	Dedicated endpoints
Start	Send requests with a Morph key	Choose model and plan; wait for provisioning
Capacity	Shared model pools	Reserved endpoint capacity
Billing	Model token usage	Hourly plans: reserved GPU time, including idle
Model name	Public catalog ID	Served name returned at readiness
OpenAI base URL	`https://api.morphllm.com/v1`	Endpoint URL plus `/v1`

Shared inference

Send your first shared API request.

Dedicated endpoints

Create, monitor, and cancel reserved capacity.

Dedicated capacity neither shrinks with traffic nor scales to zero. Review scaling before purchasing.

API formats

Shared API: https://api.morphllm.com. One key, two formats:

Endpoint	Format	Serves
`/v1/chat/completions`	OpenAI Chat Completions	All models
`/v1/messages`	Anthropic Messages	Open-source chat models
`/v1/messages/count_tokens`	Anthropic	Same

SDK examples use tabs. Anthropic Messages supports the same open source chat models, token billing, and rate limits. Fast Apply, WarpGrep, Compact, and Reflex use OpenAI format only. Authenticate with Authorization: Bearer YOUR_API_KEY or x-api-key: YOUR_API_KEY.

  max_tokens: 1024,
  messages: [{ role: "user", content: "Write a tiny rate limiter in TS." }],
});

curl -X POST "https://api.morphllm.com/v1/messages" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
  -H "Content-Type: application/json" \
  -d '{

    "max_tokens": 1024,
    "messages": [{"role": "user", "content": "Write a tiny rate limiter in TS."}]
  }'

Anthropic streaming, tools (tool_use / tool_result), system prompts, and conversation history work unchanged. Reasoning returns thinking blocks; requested thinking budgets map to effort tiers: under 8k → low, under 24k → medium, above → high.

Claude Code setup supports tools, streaming, system prompts, and conversation history. Verified with v2.1.

Anthropic folds system messages into its system prompt. In Morph, messages entries with {"role": "system"} return 400, invalid message role: 'system'. Use the separate system parameter, as Claude Code already does. Proxies injecting system messages must rewrite those entries to user until support ships.
