Tool-Callable Commerce API

Tool-Callable Commerce API

A tool-callable commerce API for teams that need OpenAPI, single-file agent references, and order-backed workflows that fit structured automation.

Flint publishes both a machine-readable OpenAPI spec and a compact `SKILL.md` reference specifically designed for coding agents.
The same public API contract covers orders, checkout, refunds, subscriptions, invoices, and onboarding, which keeps tool-calling systems on one coherent schema.
Agent tooling works better when the API surface already explains state machines, auth conventions, and object prefixes in one place instead of burying them across many pages.

Workflow Outline

01

You need an API contract that coding agents, tool routers, and automation systems can consume directly from OpenAPI or a compact reference file.

02

The team wants one structured public contract for orders, checkout, refunds, subscriptions, and onboarding rather than scattered docs and hidden conventions.

03

Your internal tooling depends on machine-readable schemas plus human-readable guidance that stays aligned with the same public API.

What This Solves

Teams searching tool-callable commerce APIs usually want a public contract that is explicit enough for agent tooling, codegen, and structured automation to consume without scraping normal docs pages manually.

Step 1

Coding-agent context injection

Give a coding agent one `SKILL.md` URL with auth conventions, API surface, and state-machine guidance instead of forcing it to scrape many docs pages.

Step 2

OpenAPI-driven tool generation

Use the public OpenAPI spec for codegen, tool definitions, and validation so your agent system stays aligned with the published contract.

Step 3

Automated onboarding loops

Bootstrap a merchant and initial API key through the public API when an automation or agent needs to handle setup end to end.

Step 4

Structured commerce toolchains

Keep orders, invoices, checkout sessions, and refunds on the same tool-callable API family so agent orchestration does not fragment across several vendors.

Why Flint Fits

Flint publishes both a machine-readable OpenAPI spec and a compact `SKILL.md` reference specifically designed for coding agents.
The same public API contract covers orders, checkout, refunds, subscriptions, invoices, and onboarding, which keeps tool-calling systems on one coherent schema.
Agent tooling works better when the API surface already explains state machines, auth conventions, and object prefixes in one place instead of burying them across many pages.

Choose Another Path When

Use the broader agent-commerce page when the main question is business workflow design rather than schema and tool-calling format.
Use scoped API-key pages when the current problem is auth boundaries instead of API readability for agent tooling.
Use regular integration pages when the workflow is purely human-operated and not tool-routed or agent-assisted.
