DeepSeek API
Give your agents access to DeepSeek API. Bring your own DeepSeek key, or skip the signup and pay per call from your Composio balance with Composio Instant.
DeepSeek offers AI-powered chat, search, and language model services. It delivers advanced conversational and information retrieval tools for smarter workflows.
What is Composio Instant?
Composio Instant lets your agent use paid APIs like DeepSeek without a separate account or API key for each one. New accounts start with $2 of free credit.
No DeepSeek account or key
Your agent calls DeepSeek through Composio, so there is nothing to sign up for, store, or rotate.
Pay per call, at cost
$0.075 per 100 successful requests; empty searches are free, paid from your Composio balance with zero markup.
