Introduction

DYLI provides APIs for reading marketplace data, building white-label commerce experiences, and using DYLI for fulfillment.

APIBase pathUse it for
Read/api/public/v1Catalogs, listings, market activity, users, Boxes, Fair Drops, metadata, rewards, and analytics.
Commerce/api/commerce/v1Build your own storefront on top of DYLI with white-label purchasing, Boxes, Collection, and fulfillment.
3PL/api/3pl/{company}Company-scoped inventory, address validation, shipping rates, outbound shipments, tracking, and vault transfers for inventory stored with DYLI.

The same API key works across the Read API and white-label catalog reads. Provisioned 3PL integrations also use their company slug.

Looking to source inventory? Buying campaigns let DYLI Pro members fund offers on cards already in PSA Vault or finishing PSA grading. DYLI places the offers based on your criteria and budget, buys cards when owners accept, and adds them to your Collection after arrival and warehouse processing.

What You Can Build​

  • Search experiences for DYLI products and collectibles.
  • Seller pages, holder views, and portfolio tools.
  • Sales, GMV, and marketplace analytics.
  • Completed collector-to-collector trade feeds.
  • Token metadata resolvers and product detail pages.
  • Box odds, inventory, pull history, and RNG verification.
  • Fair Drop, rewards, referral, digital pack, contract, and transaction widgets.
  • White-label storefronts using primary listings, secondary listings, Boxes, approved eBay inventory, USDC or card checkout, Collection delivery, and shipping redemptions.
  • Shipping and vault workflows for inventory stored with DYLI.

API Shape​

Endpoints return JSON. Read endpoints commonly use page and pageSize; Commerce resources use limit and offset. Rows that map to DYLI pages include a canonical url when available.

Send your API key with x-api-key or Authorization: Bearer <api_key>.

curl "https://www.dyli.io/api/public/v1/listings?page=1&pageSize=25" \
  -H "x-api-key: $DYLI_API_KEY"

Live Discovery​

The overview endpoint is the API index. It shows live endpoints, key requirements, and routes that are currently not supported.

curl "https://www.dyli.io/api/public/v1/overview" \
  -H "x-api-key: $DYLI_API_KEY"

See Read APIs for live endpoints, the Commerce API for partner checkout and fulfillment, and Roadmap for planned routes. Standalone raw Markdown references for all APIs are linked from the Quickstart.

Use DYLI as Your 3PL​

DYLI can receive, store, manage, vault, and ship your graded-card and sealed-product inventory. Use the 3PL API to connect fulfillment directly to your application, or use the inventory dashboard for day-to-day warehouse operations.
