description: 'Nitro Software is a document productivity company (San Francisco, CA; part of the Nitro Productivity Platform)
  offering PDF editing, eSignature (Nitro Sign), and document intelligence. Nitro publishes a public developer platform of
  REST APIs at developers.gonitro.com covering two surfaces: a PDF Services / Document Intelligence Platform API (convert,
  extract, transform, redact, OCR, generate/fill forms) and the Nitro Sign API (envelopes, documents, participants, fields,
  sealing, audit trails, and signer signing URLs). The APIs use machine-to-machine OAuth 2.0 client-credentials with short-lived
  bearer JWTs, RFC 9457 problem+json errors, cursor pagination, asynchronous jobs with callbacks, and RFC 9421 signed Sign
  webhooks. API access requires a Nitro Sign Enterprise plan.'
