TraceFast knowledge graph
TraceFast knowledge graph: the evidence behind one proven attribute of an address — the facts that were checked with their expected and observed values, the conditions that had to be false, the sources the evidence was read from, and the block the evaluation was pinned to. Path address: The address, `0x`-prefixed, 40 hex characters, any case; attribute_id: The attribute id, `family:name`, as listed by the attributes method. Docs: https://docs.tracefast.xyz/api/address-attribute-proof.md
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
