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.
