How this service works
Validate a URL/product slug against a safe lowercase hyphen pattern — 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 alr…
Output
Returns deterministic machine-readable JSON indicating whether the provided slug conforms to a safe lowercase hyphen pattern, including conformance status, any pattern violations detected, and whether the slug exceeds the optional max_len constraint.
Example use cases
Preflight slug check before publishing
“Before I publish this new blog post, can you validate the slug 'best-coffee-shops-nyc' and confirm it's under 60 characters and properly formatted?”
E-commerce product URL validation
“I'm about to create a new product page — can you check whether 'wireless-noise-cancelling-headphones' is a valid slug?”
API route segment preflight
“We're generating route slugs programmatically — validate 'user_profile_v2' and tell me if it passes the lowercase hyphen pattern check, with a max length of 40.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/slug-validateWhen to prefer
Choose this endpoint when you need a fast, stateless, deterministic preflight check on a slug's format before storing, publishing, or routing it — particularly when you want machine-readable JSON output and a sub-cent cost per call. Prefer it over custom regex logic when you want a standardized, auditable validation result without side effects.
Side effects
- Slug contains uppercase letters — returns non-conformant with pattern violation detail
- Slug contains underscores or special characters — flagged as invalid
- Slug exceeds max_len — returns length violation
- Empty slug input — returns validation error
- max_len set to zero or negative — may return error or undefined behavior
