How this service works
Call when an agent needs text rewritten with the constant case transform. No network and no LLM. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/case-constant first.
Output
The input text returned as a CONSTANT_CASE string — all letters uppercased and words separated by underscores (e.g. 'hello world' becomes 'HELLO_WORLD'). No metadata, no LLM interpretation, purely deterministic string transformation.
Example use cases
Environment variable name formatting
“Take the phrase 'database connection timeout' and convert it to constant case so I can use it as an environment variable name.”
Code constant identifier generation
“I need to turn 'maximum upload file size' into a constant case identifier for my codebase — can you do that?”
Config key normalization
“Rewrite 'api base url' in CONSTANT_CASE format for my app's config file.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/case-constant?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, offline, pure constant-case (SCREAMING_SNAKE_CASE) text conversion without any LLM interpretation or network dependency. Prefer the free sandbox endpoint (/v1/sandbox/case-constant) first; use this paid endpoint when the sandbox is unavailable or rate-limited. Ideal for programmatic code generation, config key normalization, or environment variable naming at scale.
Side effects
- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Payment of exactly $0.009 USDC required; incorrect payment amount causes a 402 response
- Non-string input type causes schema validation failure
