The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
build_launch_directory_list Build a list of places to launch a product ~495
Build a ranked list of places to submit a product launch: startup directories, product launch sites, newsletters, communities, subreddits, marketplaces, press and review pages, and optionally curated GitHub lists. Describe the product and each row comes back with the submission link, price, dofollow or nofollow, audience, rules, and a fit score, checked live today (up, moved, parked, gone, login first, submit form, prices shown, newest date on the page) and ranked by Tranco popularity. The places come from the public domain awesome-submitlist catalog. A run that does not succeed is returned as an error with its run ID. Read-only; requires an APIFY_TOKEN and is billed per place row.
| Name | Type | Req | Description |
|---|---|---|---|
| categories | array | – | Any of ai, analytics, business, community, design, developer-tools, ecommerce, indie, marketing, productivity, saas, social, software, startup. |
| check_live | boolean|string | – | Check each place's submission page today. Default true. |
| dofollow_only | boolean|string | – | Keep only places marked dofollow. Default false. |

| include_rank | boolean|string | – | Add the Tranco popularity rank. Default true. |
| keywords | array | – | Extra words to score places by. |
| max_charge_usd | string | – | Optional. The run stops before a charge that would pass this amount. |
| max_rows | – | – | Place rows per run. Default 100. |
| min_fit_score | – | – | Keep places scoring at least this, 0 to 100. Needs a description, keywords, or categories. Default 0. |
| only_new | boolean|string | – | Skip places an earlier run with the same state_key returned (free). Default false. |
| product_description | string | – | What you are launching and who it is for, for example AI meeting notes for B2B sales teams. |
| proxy_mode | string | – | auto reads a site that refuses a direct request through the Apify proxy; direct never uses a proxy. A reliability setting; it does not change the price. Default auto. |
