GET
Get passkey account
Retrieves detailed information about a passkey account including its relying party ID, public key, and current session key if not expired.

Path Parameters

  • passkey_account_address (required): The on-chain Solana address of the passkey account

Response

Returns passkey account details:

Session Key Validation

The endpoint performs session key expiration validation:
  1. Checks Blockchain Clock: Queries Solana for current slot/timestamp
  2. Validates Expiration: Compares session expiration against blockchain time
  3. Returns if Valid: Includes session_key in response if not expired
  4. Omits if Expired: session_key field not included if expired
Session validation is performed against the Solana blockchain clock, not the API server time. This ensures consistent validation across all Grid services.

Use Cases

Check Session Status

Determine if an existing session key is still valid:

Verify Passkey Existence

Check if a passkey account exists before operations:

Get Relying Party Information

Retrieve the relying party ID for cross-origin validation:

Response Fields

relying_party_id

The WebAuthn relying party identifier associated with this passkey. Limited to 32 bytes. Used for validating WebAuthn operations.

pubkey

The passkey’s public key in base58 format. This is the cryptographic public key used to verify signatures from this passkey.

session_key (optional)

Only included if a session key exists and has not expired:
  • key: Session public key in base58 format
  • expiration: Unix timestamp when session expires

Important Notes

  • Blockchain Validation: Session expiration checked against Solana clock
  • Expired Sessions: session_key omitted if expired (not an error)
  • Passkey Persistence: Passkey data persists even after session expiration
  • RP ID Limit: Relying party IDs are limited to 32 bytes
  • Cross-Origin: Relying party ID must match WebAuthn origin

Error Handling

Common errors:
  • NoValidExternallySignedAccount: Passkey address not found
  • InvalidExternallySignedAccountAddress: Malformed address
  • NotFound: Passkey account does not exist
