For Agents

Run voice and SMS broadcasts, manage phone number inventory, retrieve call recordings, and handle inbound keywords through the CallFire V2 API.

Quickstart

Get started with CallFire API in minutes using your preferred integration method.

# Add to your MCP client config (Claude Desktop, Cursor, Windsurf)
{
  "jentic": {
    "url": "https://api.jentic.com/mcp",
    "auth": "oauth"

# Then ask your agent:
"send an SMS broadcast"

# → Jentic returns the GET /events tool with parameter schema, agent executes.

View OpenAPI Document

CallFire is a voice and SMS communications platform that lets businesses run outbound dialer campaigns, send text broadcasts, manage phone number inventory, and process inbound responses. The V2 API exposes 123 operations across 90 paths grouped by calls, campaigns, contacts, keywords, media, numbers, orders, reports, texts, tickets, and webhooks. It supports broadcast lifecycle management (create, start, stop, archive), recipient batches, call recordings, text-to-speech sound generation, keyword opt-in handling, and account reporting. Authentication is HTTP Basic, which keeps integration simple for server-to-server callers.

Use Cases

Patterns agents use CallFire API API for, with concrete tasks.

★ Outbound SMS Broadcast

Send a one-to-many SMS campaign by creating a text broadcast, attaching a recipient batch, and starting the broadcast. CallFire handles delivery, retries, and per-recipient status, and exposes broadcast stats through the broadcasts/{id}/stats endpoint so the agent can report send rate and reply rate back to the user.

POST a text broadcast with the message body, add a recipient batch, then POST to /texts/broadcasts/{id}/start and poll /texts/broadcasts/{id}/stats.

Voice Broadcast Dialer

Run a recorded voice broadcast or text-to-speech announcement to a contact list using /calls/broadcasts. The lifecycle endpoints — start, stop, archive, toggleRecipientsStatus — give the agent fine-grained control over a campaign in flight, and stats and call detail records are available through the broadcasts/{id}/calls and broadcasts/{id}/stats endpoints.

POST a call broadcast referencing a TTS sound, add recipients, and POST to /calls/broadcasts/{id}/start.

Inbound Keyword Capture

Reserve a short-code keyword via the /keywords endpoints so that inbound texts to a CallFire number trigger a workflow. Combined with webhook subscriptions on /webhooks, an agent can be notified the moment a user texts the keyword and respond with an SMS broadcast or a transactional reply.

Reserve a keyword via the /keywords endpoint and subscribe a webhook on /webhooks to be notified of inbound texts containing that keyword.

Call Recording Retrieval

Pull MP3 recordings of completed calls for QA or compliance review by calling /calls/{id}/recordings to list recordings then fetching /calls/{id}/recordings/{name}.mp3 for the audio. Useful for contact centres that need to surface a specific recording in a CRM ticket without storing audio in their own systems.

GET /calls/{id}/recordings to list recordings then GET /calls/{id}/recordings/{name}.mp3 and attach the audio file to the CRM record.

AI Agent Voice and SMS via Jentic

Through Jentic, an AI agent searches for an intent like 'send an SMS broadcast' and is returned the CallFire text broadcast operation along with its input schema. Because authentication is HTTP Basic, Jentic encrypts both the username and password fragments in the credential vault and assembles the Authorization header at execution time without exposing the raw values to the agent. Setup time is under an hour.

Use Jentic search for 'send an SMS broadcast', load the text broadcast schema, and execute it with the recipient list and message body.

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

CallFire uses HTTP Basic. Jentic stores both the API username and password encrypted in the vault and constructs the Authorization header at execution time, so the agent never holds either value in its prompt or context.

Intent-based discovery

Agents search Jentic by intent (for example 'send an SMS broadcast' or 'retrieve a call recording') and Jentic returns the matching CallFire operation along with its input schema, so the agent can call the right endpoint without reading the 90-path V2 reference.

Time to first call

Direct CallFire integration: 2-5 days for Basic auth wiring, broadcast lifecycle handling, recording fetch, and webhook receiver setup. Through Jentic: under 1 hour — search for the operation, load its schema, execute.

Related APIs

Alternatives and complements available in the Jentic catalogue.

Complementary

CallerAPI

CallerAPI screens and enriches phone numbers; CallFire delivers the actual voice or SMS to those numbers.

Use CallerAPI to clean a contact list, then pass the validated numbers to CallFire as a broadcast recipient batch.

Complementary

Call Control API

Call Control flags spam-reported numbers; useful for filtering destination lists before launching a CallFire campaign.

Run a Call Control reputation check on each number and exclude flagged numbers before adding them to a CallFire broadcast.

Alternative

MiroTalk C2C API

MiroTalk C2C handles peer-to-peer video meetings while CallFire handles voice and SMS — different channels, occasionally compared for outreach workflows.

Choose CallFire for SMS or phone outreach; choose MiroTalk C2C when the conversation should escalate to a video session instead.

FAQs

Specific to using CallFire API API through Jentic.

What authentication does the CallFire API use?

The CallFire V2 API uses HTTP Basic authentication. The agent presents an Authorization header containing the base64-encoded API username and password issued in the CallFire dashboard. Through Jentic, those credentials are stored encrypted in the vault and assembled into the Authorization header at execution time.

Can I send a voice broadcast with the CallFire API?

Yes. POST a broadcast to /calls/broadcasts with the source sound (TTS, file, or call recording), add recipients via /calls/broadcasts/{id}/recipients, then POST to /calls/broadcasts/{id}/start to begin dialling. Stop it any time with /calls/broadcasts/{id}/stop.

How do I retrieve a call recording from CallFire?

List recordings for a call with GET /calls/{id}/recordings, then fetch the audio at GET /calls/{id}/recordings/{name}.mp3. The MP3 stream can be attached directly to a CRM ticket or stored in your own object store for retention.

What are the rate limits for the CallFire API?

The OpenAPI specification does not declare explicit per-endpoint rate limits. CallFire enforces account-level throughput tied to your plan and dialer concurrency — review your plan in the CallFire dashboard before scheduling large concurrent broadcasts.

How do I send an SMS broadcast through Jentic?

Run a Jentic search for 'send an SMS broadcast', load the text broadcast schema, and execute it with the recipient list and message body. Then load and execute the start broadcast schema. Install the SDK with pip install jentic and use the async search, load, and execute pattern.

Is the CallFire API free?

CallFire prices on a per-minute and per-text basis with monthly plans, plus per-phone-number rental fees. Pricing is set on callfire.com rather than declared in the spec — check the dashboard before launching a large campaign.
