## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-url-join-api-d003c74c -d '<json body>'
```

Example prompt: Can you join these form-data fields into a single URL for me — I have a JSON body with keys 'name' and 'email', the input type is http with bodyType json, and I need the output as JSON?

## When to prefer this

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.

## Known failure modes

- 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

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
