How this service works
Create Async Chat Completion
Output
Returns a job object with a unique async request ID, the model used, creation timestamp, and a status field (CREATED, IN_PROGRESS, COMPLETED, or FAILED). When completed, includes the full chat completion response with generated text, citations, and token usage/cost breakdown.
Example use cases
Example prompt
“Use Sonar deep research to answer this asynchronously: 'What are the latest breakthroughs in room-temperature superconductors as of 2025?' — use the sonar-deep-research model, search the web, and give me up to 4000 tokens in your response.”
Technical details
Endpoint
POSThttps://pplx.x402.paysponge.com/v1/async/sonarWhen to prefer
Use this endpoint when you need Perplexity Sonar completions but cannot block on a synchronous response — ideal for deep research queries, sonar-reasoning-pro tasks, or long-form generation that may take significant time. Prefer over the synchronous endpoint when integrating into workflows that benefit from polling or webhooks. Choose this over the generic Agent or Search sibling endpoints when you need full chat-style message history and model selection control.
Side effects
- Invalid or missing model enum value returns a validation error
- Messages array missing required role or content fields causes a 422
- Exceeding max_tokens limit of 128000 returns a validation error
- Payment failure or insufficient USDC balance blocks the request
- Polling a non-existent job ID returns a not-found error
- Job enters FAILED status if the underlying model or search query fails
- Timeout or service unavailability may leave job stuck in IN_PROGRESS
