API v2 (Beta)
Unsigned transaction builders and live on-chain state reads.
The v2 surface is in beta: it builds unsigned transactions for you to sign and broadcast yourself, and reads live on-chain state. It shares a base URL and an API key with v1.
- Transactions — 38 unsigned transaction builders. mallow never signs or broadcasts on your behalf.
- Marketplace — live auction, edition, and raffle state, each wrapped in a
{ viewSlot, ... }envelope. - Accounts — raw program accounts, decoded.
- Fees — mallow's sale fees and per-transaction fees.
- Staking — staking yields, totals, and fee rates.
The Fees and Staking routes are open: they need no API key.
An account that does not exist is a 200 with a null payload, not a 404 —
a settled auction and one that never existed are indistinguishable on-chain. Use
viewSlot to order a read against other reads of the same account.
