# Delx Agent Commerce — full agent reference

Delx sells deterministic, pay-per-result media and structured utility APIs to autonomous agents.
There is no buyer account, API key, subscription, or invoice. Make the request
once, read the HTTP 402 requirements, sign the exact USDC payment on Base, and
retry the same request with `PAYMENT-SIGNATURE`.

## Selection guidance

- Choose image for a fast, self-contained first purchase.
- Choose speech for short narration, accessibility audio, or an agent voice.
- Choose video draft for a low-cost four-second concept before buying a larger render elsewhere.
- Choose an entry-price utility for a $0.001 API health, OpenAPI, or x402 discovery result.
- Inputs are validated before payment.
- A settled payment is not counted as delivered revenue until the artifact is durable and hashed.
- A paid post-settlement failure enters an operator-visible full-refund queue.
