How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object containing the result of joining or composing the provided HTTP request body into a URL structure. The response shape matches the provided output example schema, returning transformed URL or request data as key-value JSON.
Example use cases
Merge API params into URL
“I have a POST request with a JSON body containing 'userId' and 'action' fields and I need those merged into a single URL-join format — can you run that through the url-join API and give me back the resulting JSON?”
Convert form-data to URL structure
“Take this form-data body with fields 'product_id' and 'quantity' and pass it through the url-join endpoint so I get back a clean composed URL as JSON output.”
Automate URL construction for agent pipeline
“In my agent workflow I need to combine a structured JSON body — with keys 'sessionId' and 'redirectPath' — into a joined URL format using the Delx url-join API, paying per result in USDC, so I can feed it to the next step.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/url-join?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-use URL joining or composition operation without signup or subscriptions, and when you want verifiable delivery with USDC micropayments on Base or Solana via x402. It is well-suited for agentic pipelines that need to programmatically construct or merge URL parameters from structured HTTP request bodies on demand.
Side effects
- Missing required 'input' or 'output' fields returns a validation error
- Invalid bodyType enum value (not json, form-data, or text) causes a schema rejection
- Payment not completed via x402 results in a 402 Payment Required response
- Malformed JSON body causes a parse error
- Unsupported HTTP method (not POST/PUT/PATCH) in the input type triggers an enum validation failure
