# Earliest KOL entry per token on Robinhood Chain (BASIC+)

`GET /rhc/kol/first-touches`

## Request

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

The **first time any tracked KOL bought** each token on Robinhood Chain — an early-entry / discovery signal. Computed read-time from `rhc_kol_trades` (a DISTINCT-ON per token yielding the global earliest KOL buy), enriched with token metadata and current/peak MC. EVM-native fields (`eth_amount`, `evm_address`, `tx_hash`, 0x). Tier: **BASIC** — but below the API-access tiers (PRO/ULTRA/BUSINESS) `limit` is clamped to 20, and the first KOL's `evm_address` is revealed only to **ULTRA/BUSINESS**.

## Query parameters

- `limit` integer
- `since` string, date-time
- `before` string, date-time
- `cursor` string
- `min_eth` number
- `token_age_max_min` integer
- `launchpad` string
- `min_mc_usd` number
- `max_mc_usd` number

## Response `200`

`next_before` is the pagination cursor (oldest first_buy_at on the page); `data_age_seconds` is the age of the newest event.

- object
  - `chain` 'robinhood'
  - `events` object[]
    - `token_address` string
    - `token_symbol` string, nullable
    - `token_name` string, nullable
    - `launchpad` string, nullable
    - `is_graduated` boolean, nullable
    - `first_buy_at` string, date-time
    - `eth_amount` number, nullable: Size of the first KOL buy in ETH.
    - `token_amount` number, nullable
    - `tx_hash` string
    - `token_age_minutes` integer, nullable: Token age at first touch.
    - `market_cap_usd_at_first_buy` number, nullable
    - `price_usd_at_first_buy` number, nullable
    - `current_mc_usd` number, nullable
    - `peak_mc_usd` number, nullable
    - `first_kol` object
      - `evm_address` string: The KOL's Robinhood-Chain wallet (0x). Present only for ULTRA/BUSINESS keys.
      - `name` string, nullable
      - `twitter_url` string, nullable
  - `count` integer
  - `next_before` string, date-time, nullable
  - `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. null on a server that predates the rhc_kol_first_touches_page migration (legacy path: no id tiebreak).
  - `has_more` boolean, nullable: Exact (limit+1 probe). null when the server is on the legacy path and cannot tell — page on next_before until an empty page.
  - `data_age_seconds` integer, nullable

## Other responses

- `400`: Invalid query parameters (e.g. min_mc_usd > max_mc_usd).
- `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.
