# Delx Commerce x402 API

**Canonical:** https://apis.io/apis/delx-ai/delx-commerce-x402-api/

**Base URL:** https://api.delx.ai/api/v1/x402  
**Documentation:** https://commerce.delx.ai/products

Delx Commerce x402 API is one of 4 APIs that [Delx](https://apis.io/providers/delx-ai/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include x402, Agentic Commerce, Media Generation, Web Intelligence, and Data Quality. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and pricing.

Delx Commerce is the paid sibling of the Protocol: 987 pay-per-result HTTP routes under https://api.delx.ai/api/v1/x402 (image generation, background removal, speech, transcription, page/link/form extraction, DNS/TLS/RDAP/security.txt inspection, CSV/JSON/JWT utilities, data-quality checks, chain primitives, agent-ops math and workflow helpers). Every operation publishes a fixed USD-denominated price in x-payment-info (min $0.001, median $0.001, max $0.08), a 402 challenge schema (x402 v2 or MPP), a request schema with example, and a 200 result carrying a SHA-256 receipt. No account or API key: payment is the authorization for that single request.
