# Signal Scorecard catalog

`GET /signals`

## Request

- Base URL: `https://madeonsol.com/api/v1`
- URL: `https://madeonsol.com/api/v1/signals`
- Auth: HTTP bearer

Discovery index of every available signal, its methodology, and the performance endpoint to fetch live efficacy. Open to any authenticated tier.

## Response `200`

OK

- object
  - `name` string
  - `description` string
  - `signals` object[]
    - `name` 'dump_cluster_count' | 'runner_rate' | 'recycled_early_buyer_count' | 'coordination_count' | 'scout_first_touch'
    - `methodology` string
    - `performance_endpoint` string, uri
  - `docs` string, uri

## Other responses

- `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`.
- `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`.
