You get: live stats on the Algorand x402 economy (active merchants and payers, 24h volume, velocity, concentration). First call free: add ?trial=1. PULSE - the x402 ecosystem market pulse: live stats on the Algorand x402 challenge economy (active merchants and payers, 24h volume and settle velocity, top performers, average ticket, concentration) computed from the facilitator's public data. A standing feed for entrants, analysts and curious agents; updates every 10 minutes.
You get: an ASA's parameters, an address's portfolio or the ledger supply, with source, round and provenance hash. First call free: add ?trial=1.

No parameters; new edition every 10 minutes, built for scheduled agents.
You get: the full Provenance research dataset in one call - every graded merchant row of the Algorand x402 Challenge wash report (A-F, claimed vs organic-adjusted volume, indicators, top payers), the cross-merchant cluster graph, the latest payer-class integrity aggregates and the published methodology. PROVENANCE DATASET - the research-grade bundle behind blocksigner.org/provenance, built for analysis, citation and audit. Attribution requested. No parameters; rebuilt every few hours.
You get: a cross-verified dossier on an Algorand address - Sol's own on-chain risk checks (age, funder, rekey, USDC opt-in, counterparties, NFD, Provenance wash grade) plus second opinions he buys from independent x402 services out of his scout wallet, with an on-chain receipt for each. SCOUT: an agent paying agents to serve you. The dossier states which opinions were obtained; if Sol cannot buy at least one, you are not charged.

New BNB Chain tokens with a honeypot check: four.meme and PancakeSwap launches, each with a simulated buy then sell once it has liquidity. BNB Chain new token launches with a honeypot check: every new four.meme token (bonding-curve progress, BNB raised, creator, and a simulated ~$1 buy then sell on the curve) and every new PancakeSwap V2 pair against WBNB, USDT, USDC, USD1 or U (scanned every 2 minutes); and once it holds $20+ of liquidity a simulated buy of about $1 then a sell of all of it…
Inspect any BNB Smart Chain address: EOA vs contract vs EIP-7702 delegated, BNB balance, nonce, proxy implementation (EIP-1967/1167/zos), and ERC-20 name/symbol/decimals/supply.
Check a BNB Smart Chain wallet's ERC-20 approvals: allowances for 8 major tokens (USDT, USDC, WBNB, BUSD...) to common spenders (Permit2, PancakeSwap v2 Router, PancakeSwap Smart Router, PancakeSwap Universal Router...); flags unlimited approvals.
Explain a BNB Smart Chain transaction: status, fee, decoded method + args (openchain signature DB), and ERC-20 transfers with symbols and human amounts.
Current gas price (gwei) on an EVM chain via on-chain read. Body: { chain }.
Stablecoin circulating supply, price and peg deviation (DefiLlama). Body: { symbol? }.
Top APY yield pools by token symbol and chain, with risk flags (DefiLlama). Body: { symbol?, chain?, limit?, safeOnly? }.
Current crypto Fear & Greed Index with 1-day change (alternative.me).
Read contract event logs across a strictly bounded block range with an optional topic0 filter and capped response count.
The other half of bridge-route. A bridge takes minutes with funds in flight, and from the source chain alone an agent cannot tell if it completed. Tracks a transfer by its source tx hash via the LiFi status API: completed (with the receiving tx), pending (poll again), failed (with the reason), or not-found (not a bridge tx, or too early to index). Pass from/to/bridge for a faster lookup. not-found reads as 'not indexed yet', never 'failed'. Not financial advice.
Bridge TVL and per-chain liquidity concentration: total value locked plus the breakdown across chains and the largest single chain's share, from DefiLlama. A liquidity-depth and concentration signal for routing decisions.
Bridge exploit track record: for one bridge, its hack history (incidents, total USD lost, funds returned, worst technique); with no bridge, a ranked leaderboard of every bridge hack by USD lost. Sourced from DefiLlama's hack dataset, joined and normalized by us.
Corridor safety verdict: given a source chain, destination chain and optional asset/amount, returns every bridge covering that corridor, each with its deterministic risk score and safe/caution/avoid tier, sorted safe-first, plus the recommended bridge and the reasons. One call to pick the safest bridge for a hop.
Cross-chain bridge safety screen: given a bridge (Stargate, Across, Wormhole, Arbitrum, CCTP, ...), returns a deterministic 0-100 risk score and a safe/caution/avoid verdict fusing its trust model, TVL depth, exploit history and governance/upgrade risk, with the reasons. One call instead of reconciling L2Beat, DefiLlama TVL and hack post-mortems yourself.
