How this service works
Join URL or filesystem-like path segments without traversal escape — 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 alre…
Output
A deterministic JSON response containing the joined and normalized path string constructed from the provided parts array, with directory traversal sequences neutralized, returned as machine-readable JSON.
Example use cases
Safe API route construction
“I have these route segments — ['api', 'v2', 'orders', '1099'] — can you join them into a clean path I can use as an API endpoint URL?”
Sanitize user-supplied file paths
“A user provided these path components: ['documents', '../secret', 'notes.txt'] — join them into a safe path that blocks any traversal escape attempts.”
Build asset URL from parts
“Combine these parts — ['static', 'images', 'avatars', 'user_42.png'] — into a properly joined URL path for my CDN asset URL.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/path-joinWhen to prefer
Use this endpoint when you need a lightweight, stateless, guaranteed-safe path join operation — especially when user-supplied input is involved and traversal attacks are a concern, or when you want a deterministic micro-utility that costs fractions of a cent and leaves no state behind. Prefer this over ad-hoc string concatenation in agent pipelines where path safety is critical.
Side effects
- Missing or empty parts array returns an error response
- Non-string elements in parts array may cause validation failure
- Payment failure via x402 protocol returns 402 status
- Malformed JSON input body returns 400-level error
