# Create an RHC coordination rule (PRO+)

`POST /rhc/kol/coordination/alerts`

## Request

- Base URL: `https://madeonsol.com/api/v1`
- URL: `https://madeonsol.com/api/v1/rhc/kol/coordination/alerts`
- Auth: HTTP bearer

Fires when `min_kols` distinct tracked KOLs buy the same Robinhood Chain token inside `window_minutes` and the cluster scores at least `min_score`. `cooldown_min` suppresses repeats per (rule, token); `score_jump_break` is an **early exit from that cooldown** when the score climbs by at least that many points (the re-fire is flagged `is_rearm`). An unknown market cap is **dropped** by the MC band, never treated as inside it.

**Scoring** uses the same v1 scorer as the Solana coordination alerts, so the number is comparable — with two differences recorded per-signal in `score_inputs`: `quality` is real (from the RHC KOL win-rate matview) while `earliness` is **defaulted**, because RHC has no early-entry measure. `density` is 1.0 by construction inside a rule's own window, so live scores start at 30.

## Request body

- object
  - `name` string
  - `min_kols` integer
  - `window_minutes` integer
  - `min_score` integer
  - `cooldown_min` integer
  - `score_jump_break` integer
  - `min_mc_usd` number, nullable
  - `max_mc_usd` number, nullable
  - `delivery_mode` 'websocket' | 'webhook' | 'both'
  - `webhook_url` string, uri

## Response `200`

Created — includes one-time webhook_secret and a `scoring` block.

- object
  - `chain` 'robinhood'
  - `rule` object
    - `id` string, uuid
    - `name` string, nullable
    - `min_kols` integer
    - `window_minutes` integer
    - `min_score` integer
    - `cooldown_min` integer
    - `score_jump_break` integer
    - `min_mc_usd` number, nullable
    - `max_mc_usd` number, nullable
    - `delivery_mode` 'websocket' | 'webhook' | 'both'
    - `webhook_url` string, uri, nullable
    - `is_active` boolean
    - `created_at` string, date-time
    - `updated_at` string, date-time
  - `webhook_secret` string, nullable: One-time HMAC secret — only present when webhook delivery is configured.
  - `scoring` object
    - `score_version` string
    - `quality` string: Real component, from mv_rhc_kol_scores winrate_7d.
    - `earliness` string: Defaulted — RHC has no early-entry equivalent.
    - `note` string
  - `note` string

## Other responses

- `400`: Invalid body or MC band.
- `401`: Missing or invalid API key, or an expired free-tier key. Authentication-stage error: no `X-RateLimit-*` headers, no `_rid`.
- `403`: Forbidden. One of: the key's tier is below this endpoint's or parameter's gate (`tier_required` with an `upgrade` block); the public demo key used outside its allow-list (`demo_key_endpoint_not_allowed`); an invalid or revoked key; an origin-restricted key called from a disallowed origin (`code` `origin_not_allowed` / `origin_required`). `X-RateLimit-*` headers are present only on `tier_required`.
- `409`: RHC coordination rule limit reached for the tier.
- `429`: Too many requests. Every 429 carries `Retry-After`. A quota 429 (`rate_limit_exceeded`, with `X-RateLimit-*`), a heavy-query concurrency 429 (`error_kind` `concurrency`/`capacity`), or the per-IP authentication-failure block (30 failed auths/min; plain `error` + `retry_after_seconds`, no `X-RateLimit-*`).
- `500`: Unexpected server error from the route (`Internal server error`, with `_rid`). Safe to retry with backoff. A failed API-key lookup is a 503 `auth_backend_unavailable`, never a 500.
- `503`: The API-key or subscription lookup could not be answered (authentication stage). Retryable and not your fault: it is never counted as a failed authentication. Honour `Retry-After`; no `X-RateLimit-*`, no `_rid`.
