## Tools (5)

- `nexez_directory`: Browse published Nexez listings without requiring a buyer query. All filters are optional. Returns directory JSON text with listing summaries and readiness information. Use nexez_search when you need ranked matches for a specific buyer request.
- `nexez_get_page`: Fetch one listing's structured agent manifest as JSON text, including seller profile, offers, configuration requirements, and published actions. Use a slug returned by search or directory; inspect exact offer identifiers and requirements before validation.
- `nexez_search`: Find services or products for a specific buyer request. Returns JSON text with ranked results, structured offers, listing slugs, agent.json URLs, and applied filters. Use nexez_directory for broad browsing, then nexez_get_page to inspect an exact offer before a dry run.
- `nexez_validate_checkout`: Dry-run checkout for an exact published offer. Returns validation JSON text with offer readiness or errors and missing requirements. Inspect the offer with nexez_get_page first. Never charges or creates an order; a successful check is not a completed purchase.
- `nexez_validate_negotiation`: Evaluate proposed terms against an exact offer and the seller's published rules in a forced dry run. Returns rules-evaluation JSON text or validation errors. Inspect the offer first and supply its required terms. Never submits a proposal, contacts a seller, or writes a negotiation.
