How this service works
TokenBrief: Analyze a Base ERC-20 address with block-linked supply, owner/proxy observations and Uniswap v2/v3 + Aerodrome Slipstream pools (USDC/WETH). Returns spot quotes, pool inventory and evidence; wallet checkout and PNG cards at /tokenbrief. Optional narration=ai adds OpenAI commentary; default rules. No security verdict, holder concentration or sellability test. Cache up to 60s, disclosed. Source or AI failures are not settled.
Output
Returns a structured brief containing: block-linked token supply, owner and proxy contract observations, scoped Uniswap v3 pool data (USDC/WETH pairs), spot price quotes, pool inventory figures, and supporting evidence. If narration=ai, also includes OpenAI-generated commentary. A share-card viewer is available at /tokenbrief. Response is cached up to 60 seconds. Does not include security verdict, holder concentration analysis, or sellability assessment.
Example use cases
DeFi researcher vetting a new token
“Can you pull a TokenBrief on the Base token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA0291 and give me the AI narration so I understand the supply situation and Uniswap pool depth?”
Trader checking spot price and pool liquidity
“What's the current spot price and Uniswap v3 pool inventory for the Base ERC-20 token at 0x4200000000000000000000000000000000000006 — use rules narration, I just need the raw data.”
Developer auditing token contract ownership
“Run a TokenBrief on 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb on Base and tell me what the owner and proxy observations look like along with any evidence flagged.”

Endpoint
POSThttps://agent-research-api.onrender.com/v1/token-brief?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, consolidated on-chain snapshot of a Base network ERC-20 token — supply, ownership, proxy status, and Uniswap v3 liquidity — in a single call. Prefer it over generic block explorers when you need structured, agent-consumable output with optional AI narrative framing. Not suitable when you need security scoring, holder concentration analysis, rugpull detection, or multi-chain token data.
Side effects
- Invalid or non-Base ERC-20 address returns validation error
- Token not found on Base chain returns empty or error response
- Uniswap v3 pool not found for USDC/WETH pair returns missing pool data
- OpenAI narration failure when narration=ai returns partial result or falls back to rules
- Rate limiting or upstream RPC failures may return 5xx errors
- Cached stale data (up to 60s) may not reflect the most recent on-chain state
- Render.com cold start may cause initial latency spike
