# Launch-bundle detection on a Robinhood Chain token (BASIC+)

`GET /rhc/tokens/{address}/bundle`

## Request

- Base URL: `https://madeonsol.com/api/v1`
- URL: `https://madeonsol.com/api/v1/rhc/tokens/{address}/bundle`
- Auth: HTTP bearer

Detects a coordinated launch bundle in a token's earliest-buyer cohort and measures how much of what the bundle bought it still holds. Mirrors the Solana `/tokens/{mint}/bundle` detector: rank the first 20 distinct buyers by on-chain order, flag a bundle when 3+ of them make their first buy in the **same block**, then report the cohort's current-held %. Robinhood Chain is an Arbitrum Orbit L2 with no atomic multi-signer transaction, so there is no `atomic_tx` kind — a detected bundle is `same_block` (else `none`). Scores tokens ingested live (the near-launch window where bundling happens). Field-gated by tier: **BASIC** gets the scalar `bundle` signal only; **PRO** adds the top-10 wallets; **ULTRA** returns the full cohort enriched with alpha-wallet identity (win-rate, bot, KOL).

## Path parameters

- `address` string, required

## Query parameters

- `include_balances` boolean

## Response `200`

OK. `wallet_count` 0 with `bundle_kind: none` when no same-block early-buyer cluster is present.

- object
  - `chain` 'robinhood'
  - `token_address` string
  - `bundle` object
    - `wallet_count` integer: Bundle-cohort size (0 when none).
    - `bundle_kind` 'same_block' | 'none': `same_block` = 3+ early buyers first-bought in one block; `none` = no cluster. `atomic_tx` does not exist on EVM.
    - `held_ratio` number, nullable: Net tokens still held ÷ tokens bought, [0,1]. The primary signal.
    - `held_pct_of_supply` number, nullable: Net tokens held ÷ total supply, [0,1]; null when supply is unknown.
    - `fully_exited` boolean: True when the cohort holds ≤0.5% of what it bought.
    - `buy_volume` number: Cohort cumulative buy-side token volume (human-scaled).
    - `tokens_held` number: Cohort net position (Σbuys − Σsells, human-scaled).
    - `holdings_basis` 'swap_only' | 'swap_and_transfers': swap_only = token transfers are not applied: a member that transferred tokens out and sold elsewhere still reads as holding.
  - `held_now` object: Only with include_balances=true (PRO+). Balance-based, next to the swap-derived bundle.* figures.
    - `source` 'rhc_node_balanceOf_latest'
    - `checked_at` string, date-time
    - `wallets` integer
    - `verified_wallets` integer
    - `holding_wallets` integer
    - `complete` boolean: True only when every cohort wallet was read.
    - `incomplete_reason` string, nullable
    - `tokens_held_raw` string, nullable: Exact uint256 sum; null unless complete.
    - `tokens_held` string, nullable: tokens_held_raw / 10^decimals, exact; null unless complete.
    - `held_pct_of_supply` number, nullable: RATIO in [0, 1] of total_supply_raw (like bundle.held_pct_of_supply); null unless complete and supply known.
    - `supply_basis` 'total_supply_raw' | 'null', nullable
  - `wallets` object[]: Empty for BASIC; top-10 for PRO; full cohort for ULTRA.
    - `rank` integer: Early-buyer rank (1 = first buyer).
    - `wallet` string: Buyer wallet (lowercase 0x).
    - `held_ratio` number, nullable
    - `has_sold` boolean
    - `is_kol` boolean: Wallet is a tracked RHC KOL.
    - `balance_now` object, nullable: Only with include_balances=true: this wallet's current balanceOf(token) from our node; unverified never means zero.
      - `status` 'verified' | 'unverified'
      - `balance_raw` string, nullable
      - `decimals` integer, nullable
      - `balance` string, nullable
      - `holding` boolean, nullable
      - `reason` string, nullable
    - `win_rate` number, nullable: ULTRA only — historical win-rate [0,1].
    - `likely_bot` boolean: ULTRA only — bot heuristic from mv_rhc_alpha_wallets.
    - `tokens_held` number: ULTRA only — net position, human-scaled.

## Other responses

- `400`: Invalid EVM token address.
- `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.
