Configuration

Each provider reads its own API key. You only need keys for the providers you actually use — an unconfigured provider fails with a clear message and suggests alternatives you do have keys for.

API keys

Provider	Env var / config key	Used by
Parallel	PARALLEL_API_KEY	web, research, scrape
Exa	EXA_API_KEY	web, scrape
Brave Search	BRAVE_SEARCH_API_KEY	web brave search
Brave Answers	BRAVE_ANSWERS_API_KEY	web brave answers, research brave
Perplexity	PERPLEXITY_API_KEY	web perplexity, research perplexity
Google/Gemini	GEMINI_API_KEY	research google
Firecrawl	FIRECRAWL_API_KEY	scrape firecrawl

Brave splits into two keys: the Search API and the Answers API are billed and provisioned separately, so web brave search and web brave answers (and research brave) can be configured independently.

Resolution order

For each key, seek resolves the first source that has a non-empty value:

1. Process environment variable — always wins. Useful for CI and one-off overrides.
2. Config file — a flat JSON object at the resolved config path.

export PARALLEL_API_KEY=…
export EXA_API_KEY=…

Config file

The config path is resolved as:

1. $XDG_CONFIG_HOME/seek/config.json when XDG_CONFIG_HOME is set.
2. ~/.config/seek/config.json otherwise.

The file is a flat JSON object whose keys match the env var names above, so you never learn a second schema:

{
  "EXA_API_KEY": "…",
  "PERPLEXITY_API_KEY": "…"
}

Only string values are read; non-string values are ignored. If the file is not valid JSON (or not a JSON object), seek prints a warning and continues as if no config file were present.

Managing the config file

The config command group manages this file:

seek config path        # print the resolved config file path
seek config init        # write a template with a placeholder for every key
seek config init --force  # overwrite an existing config file
seek config show        # show which keys are set, their source, and masked values

• config init creates the config directory (mode 0700) and writes the file with mode 0600. It fails if the file already exists unless --force is given.
• config show lists every known key, whether its value came from env, config, or is unset (—), and a masked preview of the value.
