Create a crypto charge
The headless rail: render this flow inside your own site.
The fence on POST /v3/payments exists because collecting a card means PCI
scope and a tokenizer we do not hand out. Neither applies here · the payer’s
wallet is the instrument, and a deposit address or a calldata payload is
public information. Nothing sensitive crosses the boundary.
Returns the charge plus the instruction that completes it:
qr_deposit gives an address and the exact amount to send (with a BIP21 URI
on Bitcoin); wallet_connect gives calldata for the connected wallet to
sign · ABI-encoded on EVM, a base64 transaction on Solana.
Poll GET /v3/payments/{id} for the outcome. Its deposit envelope
carries expected / received / remaining and a confirmations
counter, which is what lets you show “payment detected, 1/3 confirmations”
instead of leaving the payer on a QR code.
Where the funds end up is not decided here. Settlement routing · same-chain, or bridged to your account’s convergence target · is an account setting applied after the deposit lands. A treasury decision does not belong in a checkout call.
It does constrain ONE thing, though: an account that converges to a
stablecoin on another chain can only be paid through qr_deposit, because
the bridge needs a Suby-held address to move funds out of. Asking for
wallet_connect on such an account returns
CRYPTO_AUTOSWAP_MODE_NOT_SUPPORTED rather than quietly settling in the
source asset on the source chain.

Secret API key. sk_live_… (production) or sk_sandbox_… (sandbox).
Headers
Optional key (≤255 chars, e.g. a UUID v4) that makes this POST safe to retry: the first request executes and its response is cached for 24h; a retry with the SAME key replays that response instead of re-executing (no duplicate payment/subscription). A reused key with a different request → 422 IDEMPOTENCY_KEY_CONFLICT; a retry while the first is still in flight → 409. See the Idempotency guide.
Maximum string length:
255Example:
"5f3b9c2e-1a4d-4f2b-9c31-7e2a1b6d8c04"
Body
application/json
Pricing: productId (the product's price snapshot) OR priceCents + currency. A customer is always required · the deposit address is HD-derived from one, and receipts, refunds and access all hang off it.
qr_deposit returns an address the payer sends to; wallet_connect returns calldata their wallet signs.
Available options:
qr_deposit, wallet_connect From GET /v3/crypto/assets.
Example:
8453
The token's ticker on that chain, case-insensitive. (chainId, asset) is the public key · there is no numeric asset id on this surface, because ours means nothing outside our database.
Required string length:
2 - 12Example:
"USDC"
How a customer is named in a request body: exactly one of id or email. With id the name fields are ignored · the customer already has them on file. With email the customer is created on the fly (email is the get-or-create key). Supplying both, or neither, is a validation error.

Example:
"pro_abc123"

Pattern:

Pattern:

200Maximum string length:
500wallet_connect only · the connected wallet's address (Solana fee payer, EVM sender). Omit to charge the customer's HD-derived address.
Maximum string length:
120Key-value pairs. ≤50 keys, keys ≤40 chars, values are
strings ≤500 chars (or null to clear). Nested structures must be
JSON-stringified into a single string value.
