Attributes Proof

by TraceFast in Weather & location

x402 APIPassing, checked 4 h ago

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
