# A Robinhood Chain developer's launches and own-token buys/sells as one timeline (PRO+)

`GET /rhc/deployer-hunter/{address}/activity`

## Request

- Base URL: `https://madeonsol.com/api/v1`
- URL: `https://madeonsol.com/api/v1/rhc/deployer-hunter/{address}/activity`
- Auth: HTTP bearer

The REST timeline behind the `rhc:dev_activity` WS channel (2026-10-15). Events: `launch` (a token whose recorded deployer is this address), `dev_buy` / `dev_sell` (a trade of one of those tokens by this address itself, the effective trading account with ERC-4337 senders resolved). Same developer definition as the WS producer, and `event_id` equals the WS event id, so REST and WS can be joined. `attribution` `creator` = seen at launch, `pool_creator` = only the first pool's creator is known (weaker).

One event per trade leg, newest first, keyset paged over both sources with `next_cursor`. The trade scan is bounded: `coverage.scan_truncated` + `next_cursor` say where it stopped, never a false end. Window: `since` (default 30 days, at most 90). `coverage.dev_trades_complete_from` is the later of the window start and the Postgres floor; older months are in the archive and not read (`archive_required_before`).

**Not included (v1):** developer token transfers, trades from other wallets of the same person, history below `dev_trades_complete_from`. An empty timeline is not proof that nothing happened outside those bounds.

## Path parameters

- `address` string, required

## Query parameters

- `limit` integer
- `since` string, date-time
- `types` string
- `cursor` string

## Response `200`

OK. An address with no attributed token returns an empty timeline with `coverage.tokens_attributed: 0`.

## Other responses

- `400`: Invalid address or query parameters
- `401`: Missing or invalid API key, or an expired free-tier key. Authentication-stage error: no `X-RateLimit-*` headers, no `_rid`.
- `403`: Tier gate - PRO 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
