# Standalone crypto analysis

It's better to create an applicant action or request a payment method to perform the crypto check for particular applicants. But if there is no way to bind a crypto wallet or a transaction to an applicant then you should use standalone methods.

# Entities interactions

GET /resources/standalone/crypto/btc/interaction/{from}/{to}

# REQUEST ATTRIBUTES
Name Type Required Description
from String Yes Source of interaction (sender)
to String Yes Target of interaction (receiver)
# Example request
# Example response

# Crypto transactions

GET /resources/standalone/crypto/btc/txn/{txn}/info

# REQUEST ATTRIBUTES
Name Type Required Description
txn String Yes Transaction hash
# Example request
# Example response

# BTC wallet info

GET /resources/standalone/crypto/btc/wallet/{wallet}/info

# REQUEST ATTRIBUTES
Name Type Required Description

# Example request
# Example response

# BTC wallet statistics

GET /resources/standalone/crypto/btc/wallet/{wallet}/stats

# REQUEST ATTRIBUTES
