Every endpoint you need

Six endpoint families cover the full XDC chain surface. Every route is documented interactively in the Swagger UI.

Addresses

Balances, coin balance history, and counters for any XDC address.

Tokens

XRC-20 / XRC-721 metadata, holders, and transfers across the network.

Smart Contracts

Verified contract source, ABIs, and read/write methods.

Stats

Network-wide metrics: total blocks, transactions, gas, and prices.

Rate limits & fair use

The XDC API is free for public use under a fair-use policy. Anonymous requests are rate-limited per IP; limits are tuned for typical dApp and integration workloads. If you are building something heavier — indexing, backfills, or high-frequency polling — reach out via the contact form and we will work out a plan.

When a limit is hit the API responds with HTTP 429 — back off and retry, or add caching on your side.
