How this service works
Launch data for Robinhood Chain and Solana, updated every 20 s (≤30 s lag). Robinhood Chain: every ETH-quoted Uniswap v4 and v3 pool created in the last 24 h. Solana: pump.fun tokens 5 min to 4 h old that show curve progress. Buyer bursts, a rug check on who holds each pool's liquidity (per burst, and per token before you buy), new pools, per-minute flow, repeat-buyer crews and copy-leader replays. Robinhood signals are scored 30 minutes later, Solana ones at graduation or 20 minutes, rugs counted. Data, not trading advice. Paid per call with x402 (USDC on Base or Solana); no API keys. Every schema property carries x-available: signal = Known when the burst fires. Safe to use as a feature. signal+seconds = Filled 5-60 s after the signal, computed from chain state as of the signal block. Safe as a feature once present; null until then. signal+30m = Outcome. Exists only after the scoring window closes (Robinhood 30 min; Solana graduation or 20 min). Never use as a feature: a backtest that does uses the future. now = Current state as of the response's generatedAt (or the row's checkedAt). Not tied to a signal. Errors (4xx/5xx) are never charged. /v1 is canonical; the original paid paths are also served unversioned.
Output
A JSON array of historical pump.fun burst events on Solana, each containing: burst timestamp, mint address, token age in minutes, curve progress from/at burst, SOL inflow, window seconds, buyer anatomy (buys, unique buyers, top holder shares, bundled share, repeat buyers), and a scored outcome object including 20-minute return, peak return, rule return, graduation status, and graduation return. Also includes chain identifier, SOL/USD price at time of generation, schema version, and data age in seconds.
Example use cases
Backtesting pump.fun burst signals
“Give me 24 hours of Solana burst history from Paxie so I can see which pump.fun bursts resulted in graduation and what the peak return was for each one.”
Identifying high-inflow token launches
“Pull the last 12 hours of Solana burst events from Paxie — I want to filter for bursts where inflowSol was above 10 and the token was between 5 and 60 minutes old.”
Reviewing repeat buyer crew activity
“Get me the past 3 hours of Paxie Solana burst history so I can analyze which bursts had high repeat buyer counts and what their outcomes looked like after 20 minutes.”
Technical details
Endpoint
GEThttps://api.paxie.fun/v1/sol/bursts/history?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need historical Solana pump.fun burst event data with scored outcomes — ideal for backtesting signal quality, analyzing buyer anatomy over time, or reviewing graduation rates. Prefer this over live burst endpoints when you need lookback data rather than real-time alerts. Choose this over Robinhood Chain burst endpoints when your focus is pump.fun bonding curve tokens specifically on Solana.
Side effects
- hours parameter out of range (must be 1-24) returns validation error
- x402 payment not included or insufficient USDC returns 402 Payment Required
- data temporarily unavailable if chain indexing lag exceeds 30s
- outcome fields null if scoring window has not yet closed for recent bursts
- burst list may be empty if no qualifying pump.fun bursts occurred in the lookback window
