Source and listing identity
Source: x402 Bazaar
Listing ID: x402:8626e4fba1bdd65c5ec5eb587b9cda7c506296e213375a183d9f6098c8e3f238
Topic categories are inferred from listing text. Prices are source declarations; provider terms take precedence.
A registry entry or matching company name does not establish product authorship. Compare record IDs before treating similar titles as one product.
A two-cent probe of the FactStamp engine: one small claim in, one cited answer out, receipted. Send a dated figure, a company name, a DOI/arXiv id or a package@version and get the verdict, the value and the source it rests on with our retrieval time — the same engine and the same sources the full-price doors read. Unknown is a valid answer and nothing is invented. Paid per call in USDC on Base; no pack code and no unpaid tier.

Categories and declared capabilities
Topic categories are derived from publisher text for discovery, not independently verified capabilities.
The registry does not provide a verified tools list. See the observations, when available, for any tools/list check; a published tools list does not establish that execution succeeds.
Evidence, with its limits.
This listing is indexed. Any domain claim or endpoint observation appears separately with its date and limited scope. No payment execution, factual accuracy or safety certification is inferred.
The listing completeness score measures published information only. No safety or performance score has been assigned. A signature, source listing or successful HTTP response does not certify factual accuracy or safety.
