|---|---|---|---|---|
POST/v1/adler32 Adler-32 checksum (as used by zlib) over the input payload. Faster than CRC-32 but weaker for short inputs. Returns the checksum as an unsigned integer and 8-digit hex. Non-cryptographic. | $0.002 | Base | Coinbase CDP | 1 |
POST/v1/crc16 CRC-16 over the input payload in one of several standard variants (ccitt-false, xmodem, modbus, ibm; default ccitt-false). Returns the checksum as an unsigned integer and 4-digit hex. Non-cryptographic. | $0.002 | Base | Coinbase CDP | 1 |
POST/v1/crc32 CRC-32 (IEEE 802.3 polynomial, as used by zip, gzip and PNG) over the input payload. Returns the checksum as an unsigned integer and 8-digit hex. Non-cryptographic — for error detection only. | $0.002 | Base | Coinbase CDP | 1 |
