Call when an agent needs ERC-20 metadata, proxy and owner flags, a 30-day recent
Call when an agent needs ERC-20 metadata, proxy and owner flags, a 30-day recently_deployed heuristic, and an optional holder balance for one Base token. Send token and optional holder. No LLM. Read-only. Send JSON {"token":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","holder":"0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"}. Exact $0.01 USDC on Base. Try unpaid POST /v1/sandbox/base-token-facts first.
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.
