Observe factual Aave V3 lending supply APR and Lido staking APR for on
Observe factual Aave V3 lending supply APR and Lido staking APR for one Ethereum/Base asset, with timestamps, evidence, explicit rate labels, optional filters/sort, and limitations. No ranking or investment recommendation. Call when you need currently observed supported-venue rates for one asset, not a ranking.
Fetch deterministic, token-efficient context from one public HTTPS URL
Fetch deterministic, token-efficient context from one public HTTPS URL: canonical URL, title/description, headings, clean main content, structured-data types, freshness observations, evidence, and limitations. Call when you need a bounded JSON reading of one public page without a browser, login, crawl, or LLM.
Inspect one Base ERC-20 owner/token/spender allowance with same-block
Inspect one Base ERC-20 owner/token/spender allowance with same-block balance and token metadata plus factual exposure flags. No wallet access, signing, or transaction execution. Call when you need a same-block Base allowance-versus-balance snapshot for one owner/token/spender triple.
Bounded Ethereum/Base wallet/portfolio holdings evidence: inventory, p
Bounded Ethereum/Base wallet/portfolio holdings evidence: inventory, partial DEX pricing coverage, concentration, and evidence gaps. Pre-action evidence-readiness check for whether that evidence is sufficiently complete for downstream factual reasoning. Not guaranteed net worth, investment advice, transaction approval, or execution.
Return bounded factual eth_estimateGas units and recent eth_feeHistory
Return bounded factual eth_estimateGas units and recent eth_feeHistory execution-fee evidence for one unsigned Ethereum or Base transaction. Not execution, signing, custody, trading, or a guaranteed final cost. Call when you need point-in-time gas units and recent execution-fee context before signing or submitting.
Produce a factual snapshot of current x402 payment authority for one u
Produce a factual snapshot of current x402 payment authority for one unpaid v2 requirement and one public EVM payer: selected scheme/network/asset/amount/payTo/transfer method, same-block token balance, canonical token-spender allowance when that path applies, and declared recovery-path classification. Does not sign, approve, construct a transaction, judge native gas, or recommend whether to buy.
Produce a normalized pre-sign evidence packet for one exact unpaid x40
Produce a normalized pre-sign evidence packet for one exact unpaid x402 v2 exact Base USDC requirement: request identity, selected requirement, public payer coverage, caller ceiling, optional baseline evidence, and an integrity digest. Does not sign, pay, construct a transaction, or recommend whether to buy.
Determine whether a previously accepted x402 service payment contract
Determine whether a previously accepted x402 service payment contract is still equivalent enough to proceed. Compares one live unpaid 402 challenge, using a caller-supplied GET or POST request shape, against a caller-held baseline bound to that request identity. Not uptime monitoring, a trust score, a webhook, a marketplace crawl, or a generic POST {} probe of every x402 resource.
Determine whether the bounded normalized representation of one public
Determine whether the bounded normalized representation of one public HTTPS webpage has changed since a caller-held baseline. Returns fingerprints and change status, not continuous monitoring, alerts, webhooks, semantic importance, AI summaries, or site-wide crawling.
Observe whether one x402 seller resource appears in Coinbase Bazaar me
Observe whether one x402 seller resource appears in Coinbase Bazaar merchant discovery and where the exact resource sits in the first 20 results for 1–3 buyer-supplied job-language searches. Factual evidence only. Call when you need a point-in-time Bazaar presence and top-20 search observation, not a trust, SEO, or remediation score.
