Robinhood Chain token discovery (PRO+)

Ordering (all descending unless noted): most recent trade, market cap, current liquidity, all-time-high MC, newest (first_seen_at DESC — the launch feed; unpriced tokens list with null price fields; response adds next_since), or oldest (first_seen_at ASC — a resumable backfill walk through the full historical token set; response adds next_after + has_more).

Only with sort=newest: tokens first seen at or after this ISO8601 time (inclusive — first_seen_at is block-second granularity and several tokens can share one second, so the cursor row repeats; dedupe on token_address). Feed back the response's next_since to poll for launches.

LEGACY — prefer cursor=. Only with sort=oldest: tokens first seen at or after this ISO8601 time (inclusive). With more same-second tokens than limit it cannot advance — use cursor=. Feed back next_after (dedupe on token_address); stop when has_more is false.

Only with sort=oldest (PREFERRED over after=): the next_cursor from a previous page — a strict compound (first_seen_at, address) keyset, so the walk never repeats or skips a row and progresses with limit=1 through runs of identical timestamps. Malformed → 400; cannot be combined with after=.

Filter on whether the token has a discovered pool (primary_pool from rhc_token_prices non-null). A token can be listed (first_seen_at set) before its pool is found — pair with sort=oldest&has_pool=true for a one-time backfill of every RHC token with a pool.

equity = beacon-verified Robinhood tokenized stock/ETF (issuer beacon read from our node — never the name); other = everything else.

Minimum current market cap (USD).

Minimum current liquidity (USD).

Filter by launchpad: pons, flap, clanker, hood.fun, noxa, virtuals.

Value sorts only (market_cap / liquidity / peak_mc): exclude tokens whose last trade is older than this many days. Default 30 — a screener ranks what is tradeable; widen explicitly for dormant tokens.
