Optional API key: Bearer vulcx_.... Anonymous calls are allowed but capped at a small per-IP rate limit — see Rate limits.
Example:
"Bearer vulcx_..."
Body
application/json
Parameters for building the route instruction as a CPI target. Like InstructionsRequest, but the signer is a calling program's PDA (the on-chain authority that will invoke_signed into route) rather than a wallet.
The calling program's PDA authority — owns the token accounts and signs the swap via invoke_signed inside the integrating program.
Example:
"EJxE7RDaP5pmoVzzHRb4fufCNq3wsCgdUbJ8PCXHZNUP"
Example:
"So11111111111111111111111111111111111111112"
Example:
"uSd2czE61Evaf76RNbq4KPpXnkiL3irdzgLFUMe3NoG"
Amount in the smallest token units.
Example:
"1000000000"
Available options:
ExactIn, ExactOut Example:
"ExactIn"
Example:
50
Route corridor: multi-hop routes may only pass through these mints, closing the requiredTokenAccounts set over ATAs you pre-provisioned. Input and output mints are implicitly allowed. Empty/omitted = unrestricted.
Maximum array length:
16Example:
[ "So11111111111111111111111111111111111111112" ]
Cap on route length (1 = direct pools only). 0/omitted = server default.
Example:
2
Optional referrer wallet (base58). Receives integratorFeeBps in full, paid on-chain in the output token in the same transaction as the swap. Required whenever integratorFeeBps is set.
Example:
"EJxE7RDaP5pmoVzzHRb4fufCNq3wsCgdUbJ8PCXHZNUP"
Your own fee rate in basis points of the output, kept by you in full. Requires referrer — a rate with no wallet to pay it to returns 400. Added to platformFeeBps, not carved out of it; the sum may not exceed 100 bps.
Required range:
0 <= x <= 100Example:
20
Response
Route CPI account list built successfully.
Example:
true
The route instruction shaped for a CPI caller. Forward routeInstruction.accounts into your program's route CPI and sign with the PDA seeds. requiredTokenAccounts are the ATAs the authority PDA must own and fund before the CPI runs — this builder emits no ATA-create or wrap/unwrap instructions.
