How this service works
Validate environment variable key shape A-Z0-9 underscore — first-party local utility for agent preflight and proven micro-utils expansion. Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, no web search, no live RPC, and no mediagen. Results are advisory; the caller owns authorization, budgets, and production controls. Sibling of Delx routes that already conve…
Output
A deterministic machine-readable JSON response indicating whether the provided key string conforms to the environment variable naming convention (A-Z, 0-9, underscore, typically not starting with a digit). Includes a pass/fail result and likely details on why a key is invalid.
Example use cases
Preflight env key check in agent pipeline
“I'm about to inject a config key called my-service-token into the environment — can you validate whether that string is a legal env variable name before I proceed?”
Validating user-supplied secret name
“A user wants to store a secret under the name Secret_Key#1 — check if that's a valid environment variable key format so I can reject it with a clear message if not.”
CI/CD config key sanity check
“I have a list of proposed config keys: DATABASE_URL, 3RD_PARTY_KEY, and APP-SECRET — can you validate each one against the A-Z 0-9 underscore rule and tell me which ones fail?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/env-key-validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap, stateless, deterministic check that a string is a valid environment variable key (A-Z, 0-9, underscore) before using it in configuration, CI/CD pipelines, secret stores, or agent environment injection. Prefer it over regex-in-code when you want a canonical, versioned, machine-readable result you can audit. At $0.001 USDC it is negligible cost for preflight safety.
Side effects
- Empty or missing key field returns an error or invalid result
- Keys with lowercase letters flagged as non-conforming
- Keys containing hyphens, spaces, or special characters return invalid
- Keys starting with a digit may be flagged depending on strictness
- Network or payment failure returns no result
