Templated URL... fill in a valid value first

This resource URL still contains an unresolved template placeholder (e.g. {slug}, :slug or %7B…%7D), so the literal URL can't be paid as-is. Substitute a real parameter value before paying. Our health metrics (uptime, latency, spec-compliance) are still measured correctly and apply to the resolved URL. Price and pay-to may vary per item; that per-item variance carries no stability or hijack penalty. This is a per-item endpoint: we saw 2 distinct pay-to wallets over 30 days (one per item/author is expected, not a hijack). Always pay the pay-to in the live 402 quote, not a cached listing.

Advertised descriptionEVM Contract Introspection (arbitrum). Arbitrum contract introspection: contract vs wallet (incl. EIP-7702 delegation), bytecode size, proxy detection (EIP-1967 and legacy OpenZeppelin slots) and ERC-20 name, symbol, decimals, total supply.(Provider-supplied: an unverified claim, not checked by us. The trust grade above is our independent measurement.)
