}Router
Route and Pay from a Commerce Grant
The OAuth counterpart of POST /api/v1/router/route, for a credential minted from a
commerce authorization. Identical behaviour and identical response — with one difference:
you do not choose the delegation. It is derived from your grant: the capped, expiring
mandate the user approved when they connected you. Sending a delegationId is refused, not
ignored.
The cap, its expiry, and the user revoking the grant are the boundary on what you can spend. The routing fee is drawn from that same cap, in addition to each merchant’s price.
A plain (non-OAuth) API key cannot use this route — it has no grant to derive from. Use
POST /api/v1/router/route and name your own delegationId instead.

}Authorizations
Your Nevermined API Key (starts with 'nvm:'). Get one at nevermined.app under Settings > API Keys.
Body
application/json
Idempotency key — REQUIRED for routed payments (mode B). The Router makes the upstream call and pays automatically, so a retry after a dropped connection must not double-spend. At most one payment is minted per (caller, requestId); a duplicate returns 409 (BCK.ROUTER.0002) carrying the original paymentId, rather than paying again.
Example:
"order-1234"
Absolute upstream URL to route to (http/https only). Provide EXACTLY ONE of url or slug — both together is a 400. Use slug for a cataloged service (the opaque broker); url is for an off-catalog target you already hold the URL of.
Example:
"https://agent.example/api/resource"
Catalog slug to invoke via the opaque Router broker. The Router resolves the slug to the real upstream server-side, so the URL is never exposed. Mutually exclusive with url.
Example:
"webscrape-pro"
Optional subpath appended to the resolved upstream when slug is used (e.g. scrape → the merchant's /scrape). Path segments only — it may not change the host, so //, @, .. and an embedded absolute URL are rejected (400). Ignored when url is used.
Example:
"scrape"
HTTP method to use for the upstream request.
Available options:
GET, POST, PUT, PATCH, DELETE Headers to forward to the upstream (e.g. the agent’s own auth). Optional.
Request body to forward (JSON). Optional.
Payment protocol. On the mode-B proxy (/route, /proxy) this is ADVISORY: the Router AUTO-DETECTS the protocol from the upstream 402 — WWW-Authenticate: Payment → mpp; accepts / PAYMENT-REQUIRED → x402 — and the DETECTED protocol is authoritative for the mint (a mismatching hint here does not change what gets paid).
Available options:
x402, mpp Response
Upstream response, relayed.
The upstream HTTP status code that was relayed.
Example:
200
The upstream response body (parsed JSON when the upstream returned JSON, else a string).
Example:
{ "ok": true, "data": "the paid resource" }
Whether a payment was made (false = the upstream was free).
Example:
true
The payment made, when paid is true.
