AgentPhone

AgentPhone is the telephony infrastructure layer for AI agents. A single REST API provisions real US/Canada phone numbers for agents with voice calling, SMS, MMS, and iMessage built in, plus unified webhooks, automatic conversation threading, real-time call transcription, hosted-LLM or webhook voice modes, and 10DLC/A2P compliance handled for you. Official Python and TypeScript SDKs and a published MCP server let agents buy numbers, place calls, and send messages through natural language. Founded 2026 (Y Combinator), used by teams at Google ADK, Replit, LangChain, Sim AI, and Alchemy.

AgentPhone publishes 19 API contracts indexed on the APIs.io network, including Agent Webhooks API, Agents API, Calls API, and 16 more. Tagged areas include Company, Telephony, Phone Numbers, SMS, and Voice.

The AgentPhone catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

AgentPhone’s developer surface includes engineering blog, authentication, sandbox, documentation, getting-started guide, support, pricing, and 28 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Telecommunications regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too
Protected Resource Metadata +5 pts — a served /.well-known/oauth-protected-resource carrying `resource` (documented), and naming its authorization_servers (verified)
Agentic Commerce Well-Known Document +5 pts — a parsing /.well-known/ucp.json or acp.json declaring a version and at least one service, OR (0.27) a live x402 payment challenge from _data/x402-adoption.json — `self` when its endpoints are on the provider's own domain, `platform` when they are on a vendor's
Dry-Run / Simulate Mode +4 pts — OpenAPI: destructive operations expose a dry_run / simulate / preview / validate_only parameter

1 more unmet check in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Access Clarity scores 38.2 — up to +12.4 composite points
Operational Transparency scores 10.5 — up to +11.6 composite points
Contract Quality scores 57.1 — up to +10.7 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/agentphone/apis.yml: open an issue on github.com/api-evangelist/agentphone to ask a question or point us at an artifact you publish.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Agent Skills (SKILL.md packages)	builds-on	17.2 (thin)	1	2
Stripe App Marketplace and Partner Ecosystem (builders on Stripe)	builds-on	17.2 (thin)	1	2

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 5

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
