What's supported

What the API can and can’t do, which plan includes it, browser-run marketplaces, testing, and building for other sellers.

Webhooks

Register an endpoint, verify a signature, and handle retries correctly.

Webhook events

Every webhook event we send, what it carries, and when it fires.

MCP server

Let an AI assistant work a FLUF account directly.

UCP for AI shopping agents

FLUF speaks the Universal Commerce Protocol: agents can discover, search and look up secondhand inventory.

Machine-readable

Two OpenAPI documents, both public — you don't need a token to read them. Point a client generator at either.

openapi.yaml — the endpoints you call
events.yaml — the events we send
GET /events — every event with a sample payload, generated from the running code
