  29. 75agents.dexl.io/v1/tools/sanctions-screenScreen a person, company or vessel name against the US Treasury OFAC Specially Designated Nationals list AND its alias file - aliases matter, because a sanctioned party usually trades under an aka.

  30. 75agents.dexl.io/v1/tools/redact-piiReplace personal data in text with typed placeholders. Emails, phone numbers, cards, IBANs and IP addresses are matched by exact pattern and never left to the model - the deterministic cases cannot be missed. Names, addresses and ids are judged by a model, and output shorter than half the input is rejected, so redaction never silently deletes text.

  33. 75agents.dexl.io/v1/tools/summarize-textSummarize text into a set number of sentences, or into bullet points. Uses only what the text says and adds nothing.

  34. 75agents.dexl.io/v1/tools/extract-dataPull named fields out of free text as JSON - names, dates, amounts, references, anything you list. Every field you ask for appears in the answer: one the text does not contain comes back null rather than guessed, so "not in the text" and "model did not answer" are never confused. Fixed price per call.$0.01 $0.001 Base1055 ms1 payers100% up
  35. 75agents.dexl.io/v1/tools/classify-textAssign text to one of the labels you supply - support tickets, intents, topics, spam or not, anything.
