Workflow

Step 1 — Identify Analysis Targets and Select Nodes

Clarify the research objective and map it to one or more nodes. Typical entry points:

• User research: Use fetch_reddit_app_user_profile → fetch_users_active_subreddits → fetch_user_public_trophies.
• Subreddit audit: Use fetch_reddit_app_subreddit_info → fetch_reddit_app_subreddit_rules_and_style_info → fetch_reddit_app_subreddit_post_channels.
• Search workflow: Use fetch_reddit_app_search_typeahead_suggestions to refine query, then fetch_reddit_app_dynamic_search_results for full results.
• Trend monitoring: Use fetch_reddit_app_trending_searches (no parameters required).

Subreddit Identifier: subreddit_name vs. subreddit_id

Two different identifiers are used across subreddit endpoints:

• subreddit_name — the display name (e.g., technology, worldnews). Used by fetch_reddit_app_subreddit_rules_and_style_info, fetch_reddit_app_subreddit_post_channels, fetch_reddit_app_subreddit_info.
• subreddit_id — the internal ID with a t5_ prefix (e.g., t5_2qh0u). Required by fetch_reddit_app_subreddit_settings, check_if_subreddit_is_muted, fetch_reddit_app_community_highlights.

Call fetch_reddit_app_subreddit_info with subreddit_name first to obtain the subreddit_id when needed.

fetch_reddit_app_trending_searches

This endpoint requires no parameters. Call it directly to retrieve the current list of trending search topics across Reddit.

need_format Parameter

Most endpoints accept an optional need_format boolean. Set to true for sanitized/cleaned response data. Defaults to false.

Step 2 — Retrieve API Schema

Before calling any node, inspect its input schema to confirm required parameters and available options:

bash

node scripts/run.js --platform reddit --schema <tool_name>

# Examples
node scripts/run.js --platform reddit --schema fetch_reddit_app_user_profile
node scripts/run.js --platform reddit --schema fetch_reddit_app_dynamic_search_results

Step 3 — Call APIs and Cache Results Locally

Execute tool calls and persist responses to the local cache to avoid redundant API calls.

Calling a tool:

bash

# Single call with pretty output
node scripts/run.js --platform reddit --tool <tool_name> \
  --params '<json_args>' --pretty

# Force fresh data, skip cache
node scripts/run.js --platform reddit --tool <tool_name> \
  --params '<json_args>' --no-cache --pretty

Example — get user profile:

bash

node scripts/run.js --platform reddit --tool fetch_reddit_app_user_profile \
  --params '{"username":"spez"}' --pretty

Example — get user's active subreddits:

bash

node scripts/run.js --platform reddit --tool fetch_users_active_subreddits \
  --params '{"username":"spez"}' --pretty

Example — get subreddit post channels (with sort and range):

bash

node scripts/run.js --platform reddit --tool fetch_reddit_app_subreddit_post_channels \
  --params '{"subreddit_name":"technology","sort":"HOT","range":"DAY"}' --pretty

Example — get subreddit settings (requires t5_ prefixed subreddit_id):

bash

node scripts/run.js --platform reddit --tool fetch_reddit_app_subreddit_settings \
  --params '{"subreddit_id":"t5_2qh0u"}' --pretty

Example — get subreddit info:

bash

node scripts/run.js --platform reddit --tool fetch_reddit_app_subreddit_info \
  --params '{"subreddit_name":"technology"}' --pretty

Example — dynamic search for posts:

bash

node scripts/run.js --platform reddit --tool fetch_reddit_app_dynamic_search_results \
  --params '{"query":"AI regulation","search_type":"post","sort":"RELEVANCE","time_range":"month"}' --pretty

Example — get trending searches (no params):

bash

node scripts/run.js --platform reddit --tool fetch_reddit_app_trending_searches \
  --params '{}' --pretty

fetch_reddit_app_dynamic_search_results options:

Parameter	Options	Description
search_type	post, community, comment, media, user	Type of content to search (singular form)
sort	RELEVANCE, HOT, TOP, NEW, COMMENTS	Sort order (uppercase)
time_range	all, hour, day, week, month, year	Time filter
safe_search	"unset", "on", "off"	Safe search setting (string, not boolean)
allow_nsfw	"0" (exclude), "1" (include)	NSFW content filter (string, not boolean)
after	cursor string	Pagination cursor

Pagination:

Endpoint	Pagination parameter	Notes
fetch_reddit_app_dynamic_search_results	after (cursor string)	Pass cursor from previous response
fetch_reddit_app_user_profile, fetch_users_active_subreddits, fetch_user_public_trophies	—	Single-call response
fetch_reddit_app_subreddit_* endpoints	—	Single-call response
fetch_reddit_app_trending_searches	—	No parameters, single-call response

Cache directory structure:

text

.keyapi-cache/
└── YYYY-MM-DD/
    ├── fetch_reddit_app_user_profile/
    │   └── {params_hash}.json
    ├── fetch_users_active_subreddits/
    │   └── {params_hash}.json
    ├── fetch_user_public_trophies/
    │   └── {params_hash}.json
    ├── fetch_reddit_app_subreddit_rules_and_style_info/
    │   └── {params_hash}.json
    ├── fetch_reddit_app_subreddit_post_channels/

    │   └── {params_hash}.json
    └── fetch_reddit_app_trending_searches/
        └── {params_hash}.json

Cache-first policy:

Before every API call, check whether a cached result already exists for the given parameters. If a valid cache file exists, load from disk and skip the API call.

Step 4 — Synthesize and Report Findings

After collecting all API responses, produce a structured user and community intelligence report:

For user analysis:

1. User Profile — Username, karma breakdown (post/comment), account age, verification status, premium status.
2. Community Footprint — Most active subreddits, participation frequency, community diversity.
3. Achievement History — Public trophies, milestone dates, recognition type.
4. Behavioral Signals — Activity patterns, community focus areas, engagement style.

For subreddit research:

1. Community Overview — Name, subscriber count, description, creation date, NSFW status.
2. Governance Structure — Rules, posting requirements, moderation policies, style guidelines.
3. Content Architecture — Post channels, content categories, flair taxonomy.
4. Settings Profile — Posting rules, badge configuration, moderation settings.

For search intelligence:

1. Search Results — Matched posts, communities, users, or comments with relevance scores.
2. Trending Topics — Current platform-wide trending searches and emerging discussions.
3. Discovery Signals — Subreddit recommendations, user suggestions from typeahead.

Common Rules

Rule	Detail
Subreddit identifier	Use subreddit_name for info/rules/channels endpoints. Use subreddit_id (with t5_ prefix, e.g., t5_2qh0u) for settings/mute/highlights endpoints. Call fetch_reddit_app_subreddit_info first to resolve it from name.
fetch_reddit_app_trending_searches	Requires no parameters. Call with empty params {}.
need_format	Set to true for sanitized output. Defaults to false.
Dynamic search types	search_type options: post, community, comment, media, user (singular form). sort options: RELEVANCE, HOT, TOP, NEW, COMMENTS (uppercase).
Dynamic search string params	safe_search is a string ("unset", "on", "off"). allow_nsfw is a string ("0" to exclude, "1" to include). Neither is a boolean.
fetch_reddit_app_subreddit_post_channels	Accepts a range param (default: DAY) in addition to sort. Valid range values: HOUR, DAY, WEEK, MONTH, YEAR, ALL.
fetch_user_comments page_size	Supports page_size (integer, default 25) to control how many comments are returned per page.
Success check	code = 0 → success. Any other value → failure. Always check the response code before processing data.
Retry on 500	If code = 500, retry the identical request up to 3 times with a 2–3 second pause between attempts before reporting the error.
Cache first	Always check the local .keyapi-cache/ directory before issuing a live API call.
