Request parameters

Parameter Type Required Description
text Array Yes The text to be moderated. For more details, see text.
timestamp Number Yes The current UNIX timestamp of the server.
nonce Number Yes Random number
signature String Yes The algorithm used for digital signature is "RSA-SHA256", and the signature will be base64 encoded. Please follow the steps below for authentication:
1. All the parameters involving in the authentication process are secretId, timestamp, and nounce. Separate them with half-width comma, obtain sign string.
2. Use your private key to generate signature based on "RSA-SHA256" algorithm, encode in base64, and obtain value of signature parameter. See Public Key Management to learn how to generate private key and upload your public for authentication.

QPS Limits

  • maximum 50 queries per second
  • maximum 10 text files per query

To increase concurrency, please contact Tuputech team.

text
Parameter Type Required Description
content String Yes The text to be moderated. Text content can be in the form of word or sentence.
contentId String No User custom ID used for specific text searching. Suggested ID format: “secretId + current time + random number”. For more information, see Request Sample.

Response Parameters

Common structure of service response data

Parameter Type Required Description
signature String Yes The algorithm used for digital signature is "RSA-SHA256", and the signature will be base64 encoded. Download Tuputech’s public key certificatefirst, and then follow the steps below for authentication:
1. JSON.parse() parses received JSON data, and return JSON object which is named“data”.
2. “data” consists of two fields: “signature”-digital signature; “json”- string format of valid data.
3. use signature to verify json based on RSA-SHA25 algorithm (output type: base64), and receive the authentication result.
4. After passing the authentication, JSON.parse() json, JSON data returned. For more information, see the description of json below.
json String Yes After parsing json by JSON.parse(json), the result contains:
message：text corresponding to code parameter.
timestamp：The current UNIX timestamp of the server.
nonce：random number

Structure after JSON parsing

Parameter Type Required Description
code Number Yes Status code of the request, see Common Status Code Description.
message String Yes Status message of the request.
timestamp Number Yes The current UNIX timestamp of the server.
nonce Number Yes Random number
summary Array No Summary of the results. Disabled by default, please contact Tuputech to enable.
[taskId] Object Yes Result of tasks. Each task has its own taskID and [taskId] data structure.
... ... No Results of other tasks and requests.
