How this service works
Looks at the first Solana slot where a token mint appears (public RPC): if its history fits in 8 pages of signatures, it counts the distinct fee payers of the transactions in that slot. Several different fee payers in one slot is a bundle-sniping signal, not proof. Mints with longer history return HISTORY_TOO_LONG; this tool cannot see Jito bundle metadata.
Output
Returns a JSON object with the mint address, a verdict (such as HISTORY_TOO_LONG or a fee-payer count result), the number of signature pages read (up to 8), the source RPC URL, a timestamp, and an optional note. If the mint's transaction history exceeds 8 pages, it returns HISTORY_TOO_LONG and cannot assess launch behavior. Otherwise it provides the count of distinct fee payers in the first slot as a bundle-sniping signal.
Example use cases
Pre-buy snipe check on new memecoin
“Before I ape into this new Solana memecoin, can you check if mint So11111111111111111111111111111111111111112 shows bundle-sniping signals — like multiple bots hitting the first slot at launch?”
Token launch fairness audit
“I'm evaluating a Solana project and want to know if their token mint 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU had a fair launch or if bundle snipers were active in the first slot.”
Flagging suspicious token for community warning
“Someone in my Discord is shilling a Solana token with mint address DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263 — can you run a bundle sniper check on it and tell me how many different fee payers hit the first slot?”
Technical details
Endpoint
GEThttps://api.fadeandco.workers.dev/api/agent-intel/bundle-sniper-detector?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, low-cost heuristic signal about whether a Solana token mint was bundle-sniped at launch, especially for newer tokens with shorter transaction histories (under ~8000 signatures). Prefer this over manual RPC inspection when automating token screening pipelines or pre-purchase due diligence on memecoins. Note that it cannot access Jito bundle metadata directly and is a signal, not definitive proof.
Side effects
- HISTORY_TOO_LONG returned when the mint has more than ~8000 signatures and the first slot cannot be reached
- Invalid or malformed mint address returns an error
- RPC unavailability or timeout from the Solana mainnet-beta public node
- False negatives: legitimate high-activity launches may show multiple fee payers without sniping
- False positives: cannot confirm actual Jito bundle metadata, only infers from fee payer count
