Consumer quickstart

Open the catalog and pick an API.
Sign in from the dashboard (GitHub OAuth when configured; Dev sign-in only with a shared secret while OAuth is pending).
Create an app → mint a key → subscribe Free.
Call the gateway with your hub key (path-style):

curl -sS "https://gateway.apibroker.dev/v1/finance/v1/health" \
  -H "X-ApiBroker-Key: apb_…"

Hosts and headers

Canonical (path-style): https://gateway.apibroker.dev/v1/{slug}/…
Host-style: https://{slug}.p.apibroker.dev/… — DNS route exists, but multi-label TLS is not ready yet; use path-style until an Advanced Certificate for *.p.apibroker.dev is issued.
Key header: X-ApiBroker-Key: apb_…

Error codes

Code	Meaning
`401`	Missing or invalid hub key
`403`	No active subscription / not entitled for this listing
`429`	Quota or rate limit exceeded for the plan
`502`	Origin upstream error or unreachable through the gateway

MCP

Discovery is live on the MCP worker: GET /v1/tools, GET /v1/registry, and JSON-RPC initialize / tools/list on POST /v1/mcp. Authenticated tools/call proxies through the gateway with your hub key (prefer the MCP worker’s service binding path; public gateway hostname from Workers can 522).
