Agent Tools · SEC Filing Proof

Live · $0.05 USDC · Base mainnet

Does the company’s SEC filing actually support this financial claim?

Send a ticker or CIK plus one financial claim. SEC Filing Proof identifies the issuer, the relevant 10-Q / 10-K period, and the matching XBRL fact, then returns supported, contradicted, or a fail-closed state with official SEC evidence. It is not a market-data feed, stock picker, or investment advice.

Production endpoint OpenAPI A2A Agent Card

# 402 is expected without an x402 payment signature.
