swiftsign_send_envelope
Send a document for e-signature. Accepts PDF as base64, recipients, and field placement. Sandbox keys (sk_test_) send immediately (watermarked test mail). LIVE keys create a DRAFT and return it for human review unless confirm: true…
swiftsign_confirm_send
Dispatch a DRAFT envelope — use after a human has reviewed an envelope that swiftsign_send_envelope or swiftsign_send_from_template returned as draft_pending_confirmation. This emails the signers. Does NOT work on envelopes already…
swiftsign_send_from_template
Send an envelope from a saved template by assigning signers to roles. Sandbox keys (sk_test_) send immediately; LIVE keys create a DRAFT for human review unless confirm: true — nothing is emailed until confirmed.
swiftsign_check_status
Check the status of an envelope — who signed, who hasn't, download links. Works in both sandbox (sk_test_ keys) and live.
swiftsign_list_envelopes
List envelopes (sent documents) with their status. Scoped to your key's mode — sandbox (sk_test_) keys see test envelopes, live keys see live.
swiftsign_void_envelope
Cancel/void an envelope that hasn't been completed yet. Signers can no longer sign a voided envelope. Works in both sandbox (sk_test_ keys) and live.
swiftsign_download_signed_pdf
Download the completed, sealed PDF (or its Certificate of Completion) for an envelope. Only works once status is COMPLETED — run swiftsign_check_status first. Does NOT work on DRAFT or SENT envelopes; nothing has been signed yet on those.
swiftsign_upgrade
Initiate the upgrade to PRO ($15/mo flat). Returns a Stripe checkout_url that a human opens once to add a card — agents cannot complete the payment themselves. Moves the account from sandbox (sk_test_) to live sends. Returns status…
swiftsign_create_embedded_url
Mint a short-lived embedded signing URL for a recipient (30-minute expiry). Returns a url to embed plus its expiresAt. The envelope must already be SENT. Works in both sandbox (sk_test_ keys) and live.
swiftsign_list_templates
List your saved templates. Scoped to your key's mode — sandbox (sk_test_) keys see test templates, live keys see live.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
