How this service works
Liquidity pools created on Base mainnet in the last 24 hours, newest first, one page per call, filterable by exchange and flag. Each pool carries measured facts, each with the block it was read at, and true/false/unknown flags, with evidence for every true or unknown one; anything missing is stated in words. No score. Payment on Base mainnet.
Output
A paginated list of liquidity pools newly created on Base mainnet within the last 24 hours, ordered newest first. Each pool includes measured on-chain facts (each tagged with the block they were read at) and a set of true/false/unknown flags (e.g. empty_pool, token_has_owner, v4_hook_present), with evidence provided for every flag that is true or unknown. Missing data is stated explicitly in words. A next_cursor is included for fetching subsequent pages.
Example use cases
Monitoring suspicious new token launches
“Pull the latest new liquidity pools on Base from the last 24 hours where token_code_appeared_in_window is true — I want to see which fresh tokens showed up in the detection window, with their evidence.”
Finding non-empty pools on a specific DEX
“List the newest Aerodrome Slipstream pools on Base mainnet that are NOT flagged as empty, starting from the most recent ones.”
Screening for proxy token pools
“Show me new Base mainnet liquidity pools from the past 24 hours where token_is_eip1967_proxy is flagged true, so I can review the on-chain evidence for each one.”
Technical details
Endpoint
GEThttps://assay.cascadiantech.com/v1/pools/new?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fresh, on-chain-verified data about newly launched liquidity pools on Base mainnet with structured flag evidence rather than a raw score. It is ideal for DeFi monitoring agents, rug-pull screening workflows, or DEX analytics that require per-pool on-chain facts and paginated traversal with exchange-level filtering. Prefer it over generic blockchain explorers when you need pre-computed flag signals (e.g. token ownership, proxy detection, v4 hooks) with evidence attached.
Side effects
- Invalid cursor format returns an error (must match block:log_index pattern)
- Unrecognized dex or flag enum value rejected
- Conflicting flag and not_flag for the same value may return empty results
- No pools found in the 24-hour window returns an empty list
- Payment not completed on Base mainnet results in 402 response
