Why this listing is complete

providerName, providerUrl, serviceName, category, categories, tags, buyerQueries, and targetBuyers are duplicated at the root.
Top endpoint rows include provider/category/search copy, prices, buyer jobs, call schemas, examples, expected response fields, and preview/pay URLs.
Proof boundaries separate internal seed/indexing proof from non-seed customer revenue.
All primary discovery routes are linked from this pack.

Proof boundary

First-party listing metadata is complete and public. Internal seed/indexing proof is not customer revenue, customer adoption, marketplace ranking, partner endorsement, or legal/compliance certification.

Customer traction claim: none. Observed non-seed customer transactions: 0. Observed external volume: $0.

Public campaign copy boundaries

Say the product is live, previewable, x402-protected, and documented.
Say first-party listing metadata is complete on Boundary Guard controlled surfaces.
Do not claim customer revenue, customer adoption, marketplace ranking, partner endorsement, or legal/compliance certification.
Treat Agentic/CDP normalized listing gaps as external propagation work until the live marketplace fields are enriched.
