Start here
Read in this order:- Platform API quickstart — your first authenticated request.
- Stand up an account — bring a user online end-to-end: creation, onboarding, KYC, first wallet.
- One of the product quickstarts, depending on what you’re building:
- Perpetual Search for agentic shopping flows.
- On-ramp with Meld for fiat on/off-ramp.
- Issue a card for the wallet-funded card flow.
- Payment links for x402 payment link flows.
Reference material you’ll come back to
- Onboarding guide — the state machine your users move through.
- KYC guide — SumSub integration and attestation handling.
- Wallets guide — multi-chain wallets and Safe smart accounts.
- IPA guide — orchestrating in-product and agent-driven actions.
- Scopes reference — the capability envelope for PINTs.
- Authentication — how your app authenticates against the Platform API.
What to skip for now
- The Verifier Guide is for services that receive Sumvin credentials, not build them. Skip it unless you are also acting as a merchant.
- The SIS Dashboard is only relevant if you are operating a federated SIS integration — configuring your own auth provider, environments, and API keys.
