Two primitives for AI trading agents on Base, Ethereum and Arbitrum. Pay-per-call in USDC on Base (x402). Free tier, no signup.
Your task → the ranked x402 / MCP tools that serve it, over the merged x402 Bazaar + MCP Registry catalog (16.7k). One pass, no LLM call. Benchmarked ~1.6× faster than Coinbase Bazaar search with matched pick quality and wider coverage.

Every token-safety tool checks the contract. None check whether the liquidity is real or the price is trustworthy — a Base pool can show $15M TVL and fill $4.

| path | price | what |
|---|---|---|
/v1/{chain}/token/{address}/report | $0.040 | The single call to make before trading an unfamiliar token. Returns real tradeable depth (vs the misleading headline TVL), depth-weighted price corroboration across every pool, and a honeypot / transfer-tax check — in one request sharing one pool read. |
/v1/{chain}/token/{address}/depth | $0.010 | Largest trade that fills within 1% / 2% / 5% price impact, measured from live quotes across every hub pool (Uniswap v3, Pancake v3, Aerodrome + Slipstream), next to the pool's headline TVL. Headline TVL lies — a $15M pool can fill $4. |
/v1/{chain}/token/{address}/corroboration | $0.010 | Derives the token's USD price independently from every pool with real depth and checks they agree. Returns a consensus price only when >=2 deep pools concur; flags single-source or disagreeing tokens and lists the dissenting / dust pools. |
/v1/{chain}/token/{address}/honeypot | $0.005 | Quotes a small buy then an immediate sell on the deepest pool. Flags a honeypot when the sell returns nothing, and reports unexplained round-trip loss (transfer tax or sell restriction) beyond normal pool fees. |
/v1/tools/select | $0.003 | Call this first, before loading tools into context. Give it your task in plain language; it returns the ranked shortlist of x402 services and MCP tools that serve it - from the merged x402 Bazaar + MCP Registry catalog (16k+ entries) - plus a 'works well with' hint for tools that pair. One fast pass over the whole catalog in ~200ms, NO LLM call, and it does not fall back to keyword-only when an embedding service times out.. |
/v1/{chain}/anomalies | $0.025 | Poll this to learn which tokens on a chain just broke: a corroboration break (deep pools started disagreeing on price), a depth collapse (real fillable liquidity dropped >50%), or a newly-appeared honeypot. A continuously-refreshed 'what changed on-chain right now' feed with real depth-truth behind each flag - so an agent does not have to scan the token universe itself. Filter with ?signal=corroboration_break|depth_collapse|honeypot_new, window ?since_s=.. |
/v1/{chain}/vault/{address}/redeem-spread | $0.010 | Compares an ERC-4626 vault share's on-chain redemption value (previewRedeem / convertToAssets) to its live market quote. |
