# Delx Commerce — X402 Resource Summary

> Delx Commerce — X402 Resource Summary is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Discovers and lists all pay-per-result x402 API resources available at a given URL, returning their endpoints, tool names, and supported blockchain networks

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-x402-resource-summary-cc88a8fc -d '<json body>'
```

Example prompt: Can you check what pay-per-result x402 API tools are available at https://api.delx.ai and list them out, using a 10-second timeout?

## When to prefer this

Use this endpoint when an agent needs to dynamically discover what x402 pay-per-result API tools are available at a given URL before deciding which ones to invoke. It is the right choice for bootstrapping agent toolchains, auditing available capabilities on a Delx-compatible service, or verifying resource availability before committing a payment. Prefer this over hardcoding resource URLs when the set of available tools may change or is unknown.

## Known failure modes

- Target URL is unreachable or returns non-200 — resource list may be empty or status reflects upstream error
- Timeout exceeded (max 15 seconds) — partial or empty result if the upstream service is slow
- Invalid URL format — request rejected with validation error
- No x402 resources found at the URL — returns empty resources array with count 0
- Network-level failure reaching the target — error response with no resource data

## 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 a status code, a list of resource objects (each with its URL, tool name, and supported blockchain networks), the total resource count, and the top-level tool name for this summary call itself.
