# Render literal templates

Build-time release reference. Runtime readiness, deployment, payment settlement and external indexing are not evaluated here. Prices are proposed; this file cannot authorize execution or payment.

Use to fill deterministic text templates without evaluating code. Replaces only exact {{name}} placeholders, where names use ASCII letters/digits/underscore/dot/hyphen and start with a letter or underscore. Values are literal strings and are never re-expanded or escaped for HTML/SQL. All recognized variables must exist; other brace syntax stays literal. At most 1,000 variables, 5,000 replacements, 200,000 value units, and 500,000 output units.

Release: 0.29.0. Built: 2026-10-06T15:38:00Z.

## Choose for
- Substitute literal named values without evaluating expressions.

## Outside this profile

Proposed nominal USD 0.005 per successful call; payer fees excluded. No verified runtime availability.
