You can search by symbol:

$ curl -X POST -H 'Content-Type: application/json' --data \
     '{"symbols": {"strncpy": "db0", "strcat": "0x000000000d800"}}' \
     'https://libc.rip/api/find'

  {
    "buildid": "d3cf764b2f97ac3efe366ddd07ad902fb6928fd7",
    "download_url": "https://libc.rip/download/libc6_2.27-3ubuntu1.2_amd64.so",
    "id": "libc6_2.27-3ubuntu1.2_amd64",
    "md5": "35ef4ffc9c6ad7ffd1fd8c16f14dc766",
    "sha1": "a22321cd65f28f70cf321614fdfd22f36ecd0afe",
    "sha256": "f0ad9639b2530741046e06c96270b25da2339b6c15a7ae46de8fb021b3c4f529",
    "symbols": {
      ...
    }
  }
]

Or by hash (buildid, sha1, md5, sha256):

$ curl -X POST -H 'Content-Type: application/json' --data \
     '{"sha1": "15ecf5c58e8749650d5fe5d641f77f3a0fffab16"}' \

    "symbols": {
      ...
    }
  }
]

Or a combination (combined via AND):

$ curl -X POST -H 'Content-Type: application/json' --data \
     '{"sha1": "15ecf5c58e8749650d5fe5d641f77f3a0fffab16", "buildid": "5ae879fe5a9ff3e6622cf0dbb19fc3a80b78ec9f", "symbols": {"dup2": "690", "puts": "2b0"}}' \

      ...
    }
  }
]

To dump a specific set of symbols, given the id of the library:

$ curl -X POST -H 'Content-Type: application/json' \
    --data '{"symbols": ["strcat"]}' \
