# Recent first-KOL-touch events

`GET /kol/first-touches`

## Request

- Base URL: `https://madeonsol.com/api/v1`
- URL: `https://madeonsol.com/api/v1/kol/first-touches`
- Auth: HTTP bearer

Every 'first KOL buy on a token mint' event. Filterable by scout tier (S/A/B/C from `mv_kol_scout_score`), KOL winrate, token age, mint suffix. Backtest: top scouts attract ≥3 follow-on KOLs within 4h ~50% of the time vs ~14% baseline. Median lead time before second KOL is 12s — for trading, subscribe to the `kol:first_touches` WebSocket channel (PRO+) rather than polling.

## Query parameters

- `include` string
- `limit` integer
- `since` string, date-time
- `before` string, date-time
- `cursor` string
- `kol` string
- `min_kol_winrate_7d` number
- `min_scout_tier` 'S' | 'A' | 'B' | 'C'
- `min_n_touches` integer
- `strategy` 'scalper' | 'day_trader' | 'swing_trader' | 'hodler' | 'mixed'
- `token_age_max_min` integer
- `min_first_buy_sol` number
- `mint_suffix` string
- `preset` 'scout' | 'fresh_launch'
- `min_mc_usd` number
- `max_mc_usd` number

## Response `200`

OK — returns `{ events, count, next_before, data_age_seconds }`. Each event has `first_kol.{name, winrate_7d, strategy, scout_tier, scout_score, n_first_touches_30d}`. ULTRA also gets `first_kol.wallet`.

  - `events` object[]
    - `token_mint` string
    - `token_symbol` string, nullable
    - `token_name` string, nullable
    - `token_image_url` string, nullable
    - `first_buy_at` string, date-time
    - `sol_amount` number, nullable
    - `token_amount` number, nullable
    - `tx_signature` string, nullable
    - `token_age_minutes` integer, nullable: Null when the token's first-seen timestamp is unknown
    - `market_cap_usd_at_first_buy` number, nullable
    - `price_usd_at_first_buy` number, nullable
    - `market_cap_usd` number, nullable: Current market cap
    - `last_price_usd` number, nullable: Current price
    - `first_kol` object
      - `wallet` string: ULTRA only
      - `name` string, nullable
      - `twitter_url` string, uri, nullable
      - `winrate_7d` number, nullable
      - `strategy` 'scalper' | 'day_trader' | 'swing_trader' | 'hodler' | 'mixed', nullable
      - `scout_tier` 'S' | 'A' | 'B' | 'C', nullable
      - `scout_score` number, nullable: Alias for swarm_3plus_pct
      - `n_first_touches_30d` integer, nullable
    - `followers_4h` integer: Only present when include=followers_4h was requested
  - `count` integer
  - `next_before` string, date-time, nullable: Pass as ?before= to page further back
  - `next_cursor` string, nullable: Opaque keyset cursor for the next (older) page — pass as `cursor=`. PREFERRED over next_before, which is a strict timestamp bound that skips same-timestamp siblings of the boundary row.
  - `has_more` boolean: false only when the feed is exhausted (not merely when the page is short).
  - `scan` object: Present when a filter had to be applied after the candidate fetch (audit F09): has_more is then false only when the candidates ran out, and scan_truncated=true means the per-request scan budget ran out first — more matches MAY exist past next_cursor.
    - `post_filtered` boolean
    - `scanned` integer: Candidate rows examined
    - `scan_truncated` boolean: The per-request scan budget ran out before `limit` matches — more matches MAY exist past the cursor/offset
    - `scan_budget` integer
  - `next_since` string, date-time, nullable: Pass as ?since= to poll only newer rows
  - `since` string, date-time, nullable
  - `data_age_seconds` integer, nullable
  - `stream` object, nullable: WS stream pointer for kol:first_touches
  - `included` string[]: Present when include=wallet was honored
  - `include_truncated` object: Present when the wallet include capped at 20 distinct wallets
  - `include_errors` object: Present when a requested include was invalid or unauthorized (e.g. include=wallet below ULTRA)

## 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`: Temporarily unavailable — a Postgres statement timeout while the dataset is under load or maintenance (`statement_timeout`, with `X-RateLimit-*` and `_rid`), or the API-key lookup itself unavailable (`auth_backend_unavailable`, authentication stage: no `X-RateLimit-*`, no `_rid`, not counted as a failed authentication). Always carries `Retry-After`; honour it.
