Tool	Description	Behaviour
get_api	Fetch a single live listing by its id or slug, including base_url, price range, network and verification state. Also returns a reliability object: score (0 to 100 or null), band (strong, established, thin, caution or unscored) and computed_at. Reliability is a running score from paid verifications, health history and payTo integrity, not a star rating and not a guarantee; unscored means it has not been computed for that listing yet. Method: https://payapi.market/how-an-agent-finds-payapi. Returns the listing whether or not it is verified, and reports payment_verified honestly. Free and read-only; spends nothing.	Read-only
list_apis	Browse the live catalogue, optionally filtered to one category. Omit category for everything. Returns settlement-verified listings only unless verified_only is false. Free and read-only; spends nothing.	Read-only
search_apis	Free-text search across the live catalogue. Matches listing name, description, category and provider name. Returns settlement-verified listings only unless verified_only is false. Free and read-only; spends nothing.	Read-only
