Pricing

This page shows pricing information to help you understand API costs. For billing setup, payment methods, and usage monitoring, visit the Admin section.

Total cost per query = Token costs + Request fee (varies by search context size, applies to Sonar, Sonar Pro, Sonar Reasoning, and Sonar Reasoning Pro models only)

Token Pricing

Token Pricing

Token pricing is based on the number of tokens in your request and response.

Model	Input Tokens ($/1M)	Output Tokens ($/1M)	Citation Tokens ($/1M)	Search Queries ($/1K)	Reasoning Tokens ($/1M)
Sonar	$1	$1	-	-	-
Sonar Pro	$3	$15	-	-	-
Sonar Reasoning	$1	$5	-	-	-
Sonar Reasoning Pro	$2	$8	-	-	-
Sonar Deep Research	$2	$8	$2	$5	$3
r1-1776 (Offline)	$2	$8	-	-	-

Token and Cost Glossary

Input Tokens

The number of tokens in your prompt or message to the API. This includes:

• Your question or instruction
• Any context or examples you provide
• System messages and formatting

Example: “What is the weather in New York?” = ~8 input tokens

Output Tokens

The number of tokens in the API’s response. This includes:

• The generated answer or content
• Any explanations or additional context
• Citations and references

Example: “The weather in New York is currently sunny with a temperature of 72°F.” = ~15 output tokens

Citation Tokens

Tokens used specifically for generating citations and references in responses. Only applies to Sonar Deep Research model.

Example: Including source links, reference numbers, and bibliographic information

Search Context Size vs Context Window

Search context size is not the same as the context window.

• Search context size: How much web information is retrieved during search (affects request pricing)
• Context window: Maximum tokens the model can process in one request (affects token limits)

Search Queries

The number of individual searches conducted by Sonar Deep Research during query processing. This is separate from your initial user query.

• The model automatically determines how many searches are needed
• You cannot control the exact number of search queries
• The reasoning_effort parameter influences the number of searches performed
• Only applies to Sonar Deep Research model

Reasoning Tokens

Tokens used for step-by-step logical reasoning and problem-solving. Only applies to Sonar Deep Research model.

Example: Breaking down a complex math problem into sequential steps with explanations

Token Calculation: 1 token ≈ 4 characters in English text. The exact count may vary based on language and content complexity.
