Configuring Prometheus to scrape the hostd endpoint

1

I have this in prometheus.yml

scrape_configs:
  - job_name: "sia_hostd"
    static_configs:
      - targets: ["localhost:9980"]
    metrics_path: "/api/metrics?response=prometheus"
    basic_auth:
      username: "admin"
      password: "***"
    scrape_interval: 300s

The problem is with the question mark character from the metrics path. Prometheus changes it to %3F, and the hostd daemon gives 404 page not found

To be more clear, if I open in a web browser this link http://myhost:9980/api/metrics?response=prometheus I see the metrics.

If I open http://myhost:9980/api/metrics%3Fresponse=prometheus I get 404 page not found

What do I write in prometheus.yml? Already tried using %3F in there, it’s worse.

Prometheus version 2.50.0-rc.0
hostd version 1.0.3-beta.1

You can set query parameters in the params field

scrape_configs:
  - job_name: hostd_host_state
    scrape_interval: 30s
    metrics_path: /api/state/host
    scheme: http
    params:
      response:
        - prometheus
    basic_auth:
      password: sia is cool
    static_configs:
      - targets: ['localhost:9980']
  - job_name: hostd_metrics
    scrape_interval: 30s
    metrics_path: /api/metrics
    scheme: http
    params:
      response: 
        - prometheus
    basic_auth:
      password: sia is cool
    static_configs:
      - targets: ['localhost:9980']
  - job_name: hostd_consensus_state
    scrape_interval: 30s
    metrics_path: /api/state/consensus
    scheme: http
    params:
      response:
        - prometheus
    basic_auth:
      password: sia is cool
    static_configs:
      - targets: ['localhost:9980']
  - job_name: hostd_wallet
    scrape_interval: 30s
    metrics_path: /api/wallet
    scheme: http
    params:
      response: 
        - prometheus
    basic_auth:
      password: sia is cool
    static_configs:
      - targets: ['localhost:9980']
  - job_name: hostd_alerts
    scrape_interval: 30s
    metrics_path: /api/alerts
    scheme: http
    params:
      response: 
        - prometheus
    basic_auth:
      password: sia is cool
    static_configs:
      - targets: ['localhost:9980']
  - job_name: hostd_volumes
    scrape_interval: 30s
    metrics_path: /api/volumes
    scheme: http
    params:
      response: 
        - prometheus
    basic_auth:
      password: sia is cool
    static_configs:
      - targets: ['localhost:9980']
