AgentLine
AgentLine provides AI-native telephony APIs, offering US and Canada phone numbers for AI agents to make and receive calls, send and receive SMS, and access call transcripts. The platform integrates with popular AI runtimes like Claude, OpenAI, and custom MCP skill files, delivering ready‑made voice agent templates and SDKs for rapid development.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles AgentLine the way a machine reads it — 35 machine-readable artifacts across 2 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — AgentLine scores 46.4/100 (developing), with a separate agent-readiness read of 54/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Why this profile is thin
the company serves an API surface but requires credentials before any description of it can be read
An API exists — we simply could not reach the contract without credentials or a sales conversation. This one is AgentLine's to change: publishing the reference and a machine-readable spec at a public URL, while keeping key issuance behind whatever gate they like, would let an integrator evaluate the API before committing to a call.

Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile AgentLine
Each block below is one kind of artifact we hold for AgentLine. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 17
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
AgentLine Agent Integration API
The Agent Integration API from AgentLine — 2 operation(s) for agent integration.
AgentLine Agent Recharge API
The Agent Recharge API from AgentLine — 1 operation(s) for agent recharge.
AgentLine Agents API
The Agents API from AgentLine — 2 operation(s) for agents.
AgentLine Auth API
The Auth API from AgentLine — 7 operation(s) for auth.
AgentLine Billing API
The Billing API from AgentLine — 6 operation(s) for billing.
AgentLine Calls API
The Calls API from AgentLine — 5 operation(s) for calls.
AgentLine Contacts API
The Contacts API from AgentLine — 2 operation(s) for contacts.
AgentLine Events API
The Events API from AgentLine — 2 operation(s) for events.
AgentLine Feedback API
The Feedback API from AgentLine — 1 operation(s) for feedback.
AgentLine Health API
The Health API from AgentLine — 2 operation(s) for health.
AgentLine Messages API
The Messages API from AgentLine — 2 operation(s) for messages.
AgentLine Numbers API

Agent Skills 4
An agent skill packages the how-to for driving these APIs from an assistant — the prompts, the sequence, the guardrails — so the knowledge to use the API travels with it.

AGENT SKILLPricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
Event Specifications 1
Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.
AsyncAPI definitions for this provider's event-driven and streaming APIs.
Agentline Cloud Webhooks
ASYNCAPISemantic Vocabularies 1
JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.
JSON-LD contexts and semantic vocabularies used across these APIs.

JSON-LDSpectral Rules 1
Governance rulesets we run against this provider's specs — the automated checks behind parts of the score. Profiling them makes the quality bar explicit and re-runnable, not a matter of opinion.

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.

This is an independent, third-party profile of AgentLine, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
