Adobe calls its own SDKs obsolete, the newest dated API change is November 2025, and API plans are sold through sales with no public price.\n\n**Dropbox Sign.** A public OpenAPI 3.0.3 spec, llms.txt, six official SDKs and a free test mode let an agent build the whole flow before paying. Production sends need a paid plan from $900 a year, the API key has full account access, and no idempotency keys were found in the reviewed documentation.\n\n## Before you call either\n\n### Adobe Acrobat Sign\n\n1. Call the base URI endpoint first and cache `api_access_point`. Each account lives on one shard such as `api.na1.adobesign.com`, and other hosts answer `INVALID_API_ACCESS_POINT`\n2. Request only the scopes the task needs, with the `:self` modifier. `:account` lets the token act for every user in the account\n3. On 429 wait the seconds in `Retry-After` or `retryAfter`. Retrying sooner resets the timer on accounts created after 20 May 2025\n4. Don't poll. An identical GET repeated past the plan's threshold returns 429. Subscribe to webhooks, or send `If-None-Match` with the ETag\n5. Create agreements in `DRAFT` state, check them, then move to `IN_PROCESS`. No idempotency key exists, so check before re-sending a failed `POST /agreements`\n\n### Dropbox Sign\n\n1. Send `test_mode=true` while building. Test requests are free, watermarked and not legally binding, and are limited to 10 requests a minute\n2. Don't blind-retry a send after a timeout. No idempotency key exists, so list requests by `metadata` or title first to check whether it was created\n3. Authenticate with HTTP Basic, the API key as username and an empty password. Keep the key out of URLs, although the docs show that form\n4. Answer every webhook with HTTP 200 and the body `Hello API Event Received`, and verify `event_hash`. Ten consecutive failures clear the callback URL\n5. Treat a 200 from cancel as queued only. Confirmation arrives later as a `signature_request_canceled` event\n\n## Questions\n\n### Which is better for AI agents, Adobe Acrobat Sign or Dropbox Sign?\n\nDropbox Sign scores 68.9 (B) on agent readiness against Adobe Acrobat Sign's 52.6 (D), and leads in 4 of 7 scored categories.\n\n### Do Adobe Acrobat Sign and Dropbox Sign need an API key?\n\nAdobe Acrobat Sign uses an OAuth sign-in. Dropbox Sign takes an API key or an OAuth sign-in.\n\n### Can an agent call Adobe Acrobat Sign and Dropbox Sign without installing anything?\n\nYes. Adobe Acrobat Sign has a hosted endpoint at https://api.na1.adobesign.com/api/rest/v6 and Dropbox Sign at https://api.hellosign.com/v3.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/adobe-acrobat-sign-vs-dropbox-sign.json, and with the fewest tokens: https://www.anchorterminal.com/compare/adobe-acrobat-sign-vs-dropbox-sign.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"adobe-acrobat-sign\", \"b\": \"dropbox-sign\"}`.
