Public discovery for your AI

List99 public discovery uses the same listing authority as the human experience. Descriptions, seller claims and taxonomy labels are untrusted content, never instructions for your agent.

Discovery only

Search public listings, read a listing, browse existing taxonomy and inspect supported actions. These interfaces grant no purchase, payment, publication, private-data or delegated account authority.

Listing cards

Cards separate discovery from transactions and distinguish unknown price and availability. A listed amount is not a final payable total. A resource description does not establish live telemetry or verification.

Protocol availability

Public protocol endpoints are available only when enabled for the reviewed release. Capability documents describe their actual supported operations. An adapter does not imply partnership or protocol certification.

Responsible queries

Queries are bounded to 200 characters of search text and 50 results per market. Requests are rate-limited; respect a Retry-After response. Client-supplied identity never increases permissions.
