The status page records three incidents affecting document creation, sending or the API between 15 July and 6 September 2026, and writes have no idempotency keys.\n\n**airSlate SignNow.** The REST API has a public OpenAPI 3.0 spec with 354 operations, Markdown docs, a free Development mode with 500 invites and a hosted MCP server with OAuth. API keys don't expire and carry full account access, no idempotency keys were found, and the MCP server's GitHub repository was archived when checked on 7 October 2026.\n\n## Before you call either\n\n### PandaDoc\n\n1. Wait for `document.draft` before sending. Creation is asynchronous and a new document stays in `document.uploaded` for a few seconds\n2. Match the region. Accounts on app.pandadoc.eu use api.pandadoc.eu and mcp.pandadoc.eu, and the global hosts reject them\n3. Check for an existing document before retrying a create. There's no idempotency key and each production create uses a usage credit\n4. Retry 409 after a pause and back off on 429. A sandbox key allows 10 requests a minute per endpoint\n5. Don't rely on webhooks alone. Failed deliveries aren't retried, so poll the status endpoint as a fallback\n\n### airSlate SignNow\n\n1. Call https://api.signnow.com with `Authorization: Bearer \u003cAPI key or access token\u003e`. Development and Live share this host, and Development documents carry a watermark\n2. Request OAuth tokens with a narrow `scope` such as `document/* GET/user`. The default `*` grants every API action\n3. Read `X-RateLimit-Remaining` and `X-RateLimit-Reset` on each response. The limit is 500 requests an hour in Development and 1,000 in Live, and 429 has no Retry-After\n4. Check invite status before resending. No idempotency key exists, and a repeated invite call counts as another charged invite\n5. Set `secret_key` when creating an event subscription and verify `X-SignNow-Signature` (HMAC SHA-256 of the body) on every callback\n\n## Questions\n\n### Which is better for AI agents, PandaDoc or airSlate SignNow?\n\nairSlate SignNow scores 68.5 (B) on agent readiness against PandaDoc's 63.1 (B), and leads in 4 of 7 scored categories. PandaDoc leads on schema \u0026 documentation and maintenance \u0026 community.\n\n### Do PandaDoc and airSlate SignNow need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call PandaDoc and airSlate SignNow without installing anything?\n\nYes. PandaDoc has a hosted endpoint at https://api.pandadoc.com/public/v1 and airSlate SignNow at https://api.signnow.com.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/pandadoc-vs-signnow.json, and with the fewest tokens: https://www.anchorterminal.com/compare/pandadoc-vs-signnow.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"pandadoc\", \"b\": \"signnow\"}`.
