Technical details
Endpoint
POSThttps://trust.zuluworksai.com/api/featured/subscribeWhen to prefer
Choose this endpoint when you want to programmatically pay to feature and badge a specific AI agent endpoint (x402, MCP, or A2A) in the ZuluWorks trust-ranked public index. Prefer this over manual submission forms when orchestrating agent-to-agent discovery workflows or when you need a machine-readable listing_id and expiry date returned immediately after payment.
Side effects

- Invalid plan value: plan enum not matching 'basic' or 'premium', returning a 400 validation error
- Malformed wallet address: wallet not a valid 0x Ethereum address, causing request rejection
- Duplicate subscription: endpoint already has an active featured listing for the given plan period
