Base Token Batch Screen is a paid API for AI agents from base-facts.yankii.fr, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-12).
Batch-screens up to 10 Base token addresses in one call, simulating buy/sell to detect honeypots, taxes, and trading risks without executing real trades.

How this service works
Base token BATCH sell check: up to 10 token addresses in one call and one payment. For each token it simulates a small buy and an immediate sell inside eth_call (no trade is sent) and returns buy tax, sell tax, round-trip loss, flags and a plain summary; a token it cannot simulate is returned as not_simulated with the reason. Built for bots that screen many new tokens: $0.03 for up to 10 (single check: $0.005). Facts, not advice.
Output
For each submitted token address, returns buy tax percentage, sell tax percentage, round-trip loss, risk flags (e.g. honeypot, high tax), and a plain-language summary. Tokens that cannot be simulated are returned with status not_simulated and a reason explaining why.
Example use cases
New token launch honeypot sweep
“I just saw 8 new tokens launch on Base in the last hour — can you batch screen all 8 addresses at once and tell me which ones have high sell tax or are honeypots? Here are the addresses: 0x111..., 0x222..., 0x333..., 0x444..., 0x555..., 0x666..., 0x777..., 0x888...”
Meme coin sniper bot pre-trade filter
“Before my bot buys any of these 10 new Base meme coins, screen them all for buy tax, sell tax, and round-trip loss so I can skip the ones that are rugs: 0xA1..., 0xB2..., 0xC3..., 0xD4..., 0xE5..., 0xF6..., 0xA7..., 0xB8..., 0xC9..., 0xD0...”
Portfolio entry risk check
“I'm considering buying into 6 Base tokens someone recommended — can you simulate a buy and immediate sell for each of these addresses and flag anything with a sell tax above 5% or that can't be sold: 0x101..., 0x202..., 0x303..., 0x404..., 0x505..., 0x606...?”
Technical details
Endpoint
POSThttps://base-facts.yankii.fr/v1/batch?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to screen multiple Base tokens in a single API call and payment, making it 6x cheaper per token than the single-token endpoint ($0.03 for 10 vs $0.005 each). Ideal for bots monitoring new token launches, sniper bots that need to pre-filter many candidates quickly, or any workflow where you have a batch of token addresses to evaluate simultaneously. Prefer the single-token endpoint only when you need trade-size-specific simulation or have just one address to check.
Side effects
- Token address is not a valid 0x-prefixed 20-byte hex — returns validation error
- Token contract not deployed on Base or is a non-standard contract — returned as not_simulated with reason
- More than 10 addresses submitted — request rejected
- Simulation fails due to contract logic (e.g. paused trading, blacklisted addresses) — returned as not_simulated
- Payment insufficient or x402 protocol error — call rejected before processing
