Connect Saperly to your AI agent
Saperly is the phone carrier for AI agents — phone numbers, voice, SMS, and compliance in one API.
We set up the connection using your own Saperly account, with keys you control, and keep it running. Your agent picks it up and starts doing the work.
Actions
What your agent can do in Saperly
Each one is a real action the agent can take on its own, the same things a person clicking around Saperly could do. Read-only by default; write actions are confirmed against your policy.
- Bind Connection to Number Attach a connection (the AI persona / answering brain from SAPERLY_CREATE_CONNECTION) to a phone number, so inbound calls and SMS to that number — and outbound calls placed from it — are handled by that connection. A nu…
- Check Consent Check whether a contact currently has active TCPA consent for one of your Saperly numbers, given numberId (your number) and peerNumber (the contact's E.164 number) as query params. Returns {hasConsent: boolean} and, whe…
- Create Connection Create a connection: the AI 'brain' that answers calls and (optionally) SMS on a Saperly phone number. A phone number binds to a connection via SAPERLY_ASSIGN_NUMBER_CONNECTION in order to answer calls. Only `name` is r…
- Delete Connection PERMANENTLY AND IRREVERSIBLY delete a connection (the AI answering brain / persona that handles calls and SMS) by its id. THIS CANNOT BE UNDONE — there is no restore. WARNING: any phone number currently bound to this co…
- End Call End an in-progress call by its id, hanging up and settling the metered cost. This is the safe, cheap, RECOMMENDED companion to SAPERLY_PLACE_CALL: placing a call starts per-minute billing, and this tool is how an agent…
- Get Call Fetch a single call by its id, returning its status, per-minute rate, final duration (durationSec) and cost (costCents), and the hasRecording / hasTranscript flags. costCents and durationSec are NULL until the call sett…
- Get Call Recording Get the audio recording for a call and return it as a downloadable file. The API answers with a 302 redirect to a signed download URL when a recording exists; the recording is fetched and returned as a file reference (u…
- Get Call Transcript Fetch the transcript (conversation turns/segments) of a completed call by its id. Transcripts only exist AFTER a call connects, ends, and is processed. The endpoint uses the same 404 for an unknown call and a valid call…
- Get Connection Fetch a single connection (the AI answering brain / persona that handles calls and SMS) by its id, returning its full config: name, mode, backend, instructions, tts voice, language, compliance/disclosure settings, recor…
- Get Phone Number Fetch a single phone number by its id, returning its E.164 phoneNumber, bound connectionId, webhookUrl, country, numberType, pricing and lifecycle fields. Use after SAPERLY_LIST_NUMBERS to inspect one number's current c…
- Get Usage & Balance Return the workspace usage summary and prepaid balance: calls {count, totalCostCents, totalDurationSec}, messages {count}, and balanceCents (the prepaid balance, in cents). ALWAYS call this before any paid action to che…
- List Calls Return the full voice-call history (inbound + outbound) for the connected Saperly workspace. Each call carries its id, numberId, direction, to and from_number (E.164), status, rateCentsPerMin, durationSec, costCents, ha…
- List Connections Return every connection (the AI persona / answering 'brain' that handles calls and SMS) in the connected Saperly workspace. Each carries id, name, mode (hosted|manual), backend, instructions, llm, tts voice, language, m…
- List Consent Records Return every TCPA consent record in the connected Saperly workspace, with each record's id, numberId (the Saperly number contact is authorized FROM), peerNumber (the contact's E.164 number), consentType (explicit_outbou…
- List Languages Return the spoken languages Saperly supports for voice connections, each as a {code, name} pair (about 42 entries, e.g. {'code':'en','name':'English'}). A language `code` is what you pass as a connection's `language` fi…
- List Messages Return SMS messages in the connected Saperly workspace (both inbound and outbound). Each message has id, numberId, direction, to, from_number, body, segments, status and createdAt. Pass `numberId` to filter to a single…
- List Phone Numbers Return every phone number provisioned in the connected Saperly workspace, with each number's id, phoneNumber (E.164), the connectionId (answering brain) bound to it, webhookUrl, country, numberType, monthlyPriceCents an…
- List Voices List the text-to-speech voices available for Saperly connections. Each voice has an id, name, gender and language; a voice id is what you pass as tts.voiceId when creating or updating a connection (SAPERLY_CREATE_CONNEC…
- Place Call PAID / METERED — places a REAL outbound voice call that RINGS A REAL PHONE and BILLS PER MINUTE (~26¢/min); it keeps billing until hung up — end it with SAPERLY_END_CALL to stop the meter. Calls FROM a Saperly number (`…
- Provision Phone Number PAID / METERED: provision (buy) a new phone number in a country. This SPENDS MONEY — it charges the workspace prepaid balance an upfront fee plus a RECURRING MONTHLY rent (US local ~ $1.79/mo, varies by country/type). B…
- Quote Number Price READ-ONLY and FREE: quote the price to provision a phone number in a country/type, returning { customerMonthlyCents, customerUpfrontCents }. This DOES NOT provision, reserve, or charge anything — despite the name it has…
- Record Consent Record TCPA consent for a contact so outbound SMS (SAPERLY_SEND_SMS) and calls (SAPERLY_PLACE_CALL) from your number are permitted. Saperly's compliance gate: for a cold contact call this BEFORE sending; confirm with SA…
- Release Phone Number PERMANENTLY AND IRREVERSIBLY release a phone number back to the carrier. THIS CANNOT BE UNDONE: the number leaves the workspace, is returned to the carrier pool, and CANNOT be recovered or reclaimed. Inbound calls and S…
- Revoke Consent Revoke a contact's TCPA consent for a given Saperly number, blocking further outbound contact to them. CALL THIS WHEN A RECIPIENT SAYS 'STOP' / 'UNSUBSCRIBE' / 'do not contact me' — honoring an opt-out is a legal compli…
- Send SMS PAID / METERED: send a single SMS from one of your Saperly numbers to an E.164 destination. This SPENDS REAL MONEY and sends a REAL text message to a REAL phone (~2 cents per 160-character segment; a long body is split…
- Set Number Caller ID Name Set the outbound caller ID name / CNAM (1-15 characters: letters, digits, spaces) presented to recipients on outbound calls from a Saperly phone number, or pass callerIdName=null to CLEAR it. callerIdName is required —…
- Set Number SMS Sender ID Set the alphanumeric SMS sender id (1-11 alphanumeric chars, e.g. a brand name) shown as the 'from' on outbound SMS from this number, or pass smsSenderId=null to CLEAR it. Returns the updated number object. NOTE: sender…
- Set Number Webhook Set the HTTPS webhook URL that Saperly POSTs this number's events (inbound SMS/calls, status) to. The url is required and must be https://. Returns the updated number object. NOTE: this endpoint has no way to clear the…
- Transfer Call PAID / METERED — BLIND-transfers a LIVE, in-progress voice call to another destination `to` (an E.164 number like +15551230000, or a `sip:` URI). BLIND means the call is handed off UNCONDITIONALLY: there is NO confirmat…
- Update Connection Partially update a connection (the AI answering brain bound to a number). Send only the fields you want to change (name, mode, instructions, llm, tts, language, mcpServers, callControl, complianceEnabled, smsAutoReply,…

How we connect it

Connect your account
You create a key in Saperly, a key you create and control, and paste it in once. It lives in a secrets store on your server, not with us.

Set the guardrails
Read-only by default. You choose which write actions the agent may take, and anything outside that policy gets confirmed with you first.
- 3
We keep it running
Health checks on every connection, updates handled for you, and we watch the first week of activity to make sure the work lands.
FAQ
Saperly questions, answered.
With a key you create and control. You paste it in once, it is stored in a secrets store on your server, permissions are scoped to the minimum the agent needs, and you can revoke it at any time.
The actions Saperly's API allows, the same things a person clicking around the app could do. Connections start read-only by default; write actions are confirmed against the policy you set before the agent takes them.
Connections are priced per tool on top of the base plan. Some are included, some are premium. See pricing for how connection charges work.
Standard tools are ready inside 7 business days of the setup call. We test the connection end to end, walk you through how the agent uses it, and watch the first week of activity.
