Honeypot Check – EVM Token Sell Simulation
x402
Honeypot Check – EVM Token Sell Simulation is a paid API for AI agents from obol-x402.fly.dev, paid per call via x402, $0.15/call, status down (last checked 2026-09-15).
Simulates whether an EVM token can actually be sold after purchase, detecting honeypot traps and measuring exact sell tax across multiple chains using KyberSwap round-trip simulation fused with honeypot.is/GoPlus per-chain analysis.

How this service works
Can you SELL this EVM token after buying? KyberSwap two-way round-trip FUSED with per-chain sellability sims — honeypot.is fork sim + exact sell tax on base/ethereum/bnb, GoPlus on arbitrum/optimism/polygon. Buyable-but-not-sellable = honeypot BLOCK. ALLOW|CAUTION|BLOCK, never ALLOW from a partial result. Query: address, chain (default base). Free teaser: /v1/evm/sell-sim/preview. Cryptographically signed (Ed25519) — every response is independently verifiable via /.well-known/obol-pubkey.
Output
Returns a signed verdict of ALLOW, CAUTION, or BLOCK indicating whether the token is sellable. Includes the simulated sell tax percentage, chain-specific simulation source (honeypot.is fork for base/ethereum/bnb, GoPlus for arbitrum/optimism/polygon), and a KyberSwap round-trip result. Response is cryptographically signed with Ed25519 and independently verifiable.
Example use cases
Pre-trade honeypot scan for new token
“I'm about to ape into this token on Base — address is 0xabc123... — can you check if it's a honeypot and whether I'd actually be able to sell it before I buy?”
Sell tax check before sniper bot entry
“My sniper bot is about to buy 0xdeadbeef... on BNB chain — run a sell simulation first and tell me the exact sell tax and whether it gets ALLOW, CAUTION, or BLOCK.”
Safety audit of token on Arbitrum
“Can you verify that this Arbitrum token at 0x9988ff... isn't a honeypot? I need to know if selling is actually possible and what verdict the simulation returns.”

Endpoint
GEThttps://obol-x402.fly.dev/v1/evm/sell-simWhen to prefer
Choose this endpoint when you need to verify whether a specific EVM token can actually be sold after purchase — especially before executing a buy trade. It is superior to generic token scanners because it performs an actual KyberSwap round-trip sell simulation fused with honeypot.is fork analysis (for base/ethereum/bnb) or GoPlus (for arbitrum/optimism/polygon), and it never returns a false ALLOW from a partial result. Prefer it over static contract scanners when you need sell-tax precision and chain-aware simulation rather than just ownership or code heuristics.
Side effects
- Invalid or non-existent token contract address returns an error
- Unsupported chain value returns validation error
- Token with no liquidity may produce inconclusive simulation
- Partial simulation results are never returned as ALLOW — they default to BLOCK or CAUTION
- Network timeout on-chain may cause delayed or failed response
- Token recently deployed with no trading history may lack simulation data
