# Solana Bundle Sniper Detector

> Solana Bundle Sniper Detector is a paid API for AI agents from api.fadeandco.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-29).

Detects potential bundle-sniping of a Solana token mint by counting distinct fee payers in its first on-chain slot

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability solana-bundle-sniper-detector-637cf276
```

Example prompt: Can you check if the Solana token with mint address EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v was bundle-sniped at launch — specifically how many distinct fee payers were in its first slot?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
