Get a provider's certificate

Returns the performance certificate this node holds for a given provider. A node answers from its own certificate when it is that provider, and otherwise from the certificates it has cached from gossip.

provider is the provider's hex-encoded ed25519 public key.

curl https://<node>/certificate/<provider>

The response body is the same certificate object documented on Get this node's certificate.

Errors

{ "error": "no certificate for provider" }

That response carries HTTP 404 — returned both for an address the node holds no certificate for and for one that is not a provider at all. Omitting the address entirely (/certificate/) does not reach this endpoint; the router answers 404 for it.

Consistency

Certificates reach a node by gossip, so this read reflects only what that particular node has cached. A provider whose certificate has not yet propagated, or whose certificate has been superseded, can read differently from one node to the next. The value that binds a lease is the certificate_hash recorded on the lease block, not whatever the provider is advertising now.
