Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (8)

`compare_apis`read-only	Compare 2-5 APIs side by side (auth, free tier, HTTPS, pricing, docs summary) to choose one. Pass slugs from search_apis.
`get_api`read-only	Everything about one API by slug (from search_apis): documentation summary, endpoints, auth, pricing and links. Use before writing integration code.
`get_deal`read-only	Status of a deal: negotiating, agreed, awaiting_approval, awaiting_payment (payment_url is included), publishing, live (live_url), rejected. Also returns the last messages.
`get_quickstart`read-only	Ready-to-run example code for calling an API, in javascript, python or curl. Use when you are about to integrate an API into code. Verified samples are marked verified=true.
`list_offerings`read-only	Ways to get an API listed or sponsored on PublicAPIs.io, with fixed prices, current sponsorship availability and the rules.
`search_apis`read-only	Find a public API or data source for a task: use this whenever the user (or your code) needs an API, dataset or third-party service, e.g. weather, geocoding, payments, sports scores, crypto prices, jobs, LLMs. Searches 1,500+ APIs on PublicAPIs.io and returns name, description, category, link and signals (auth: none/api_key/oauth, free_tier, https). Filter with auth="none" for APIs that need no key, free=true, https=true.
`send_message`	Reply to the broker in an open deal. Returns the broker's answer and the deal status.
`start_deal`	Open a conversation with the PublicAPIs.io broker agent to list or sponsor an API. Say what you want in plain language and include the API name, website and a contact email if you have them. Returns deal_id and deal_key (keep both; they are needed to continue) and the broker's reply. Every deal is approved by a person before payment.
