Agent Mercantile · api.agentmercantile.com
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.
https://api.agentmercantile.com/v1/allowance-exposure
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.
https://api.agentmercantile.com/v1/bazaar-visibility
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.
https://api.agentmercantile.com/v1/payment-authority-snapshot
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.
https://api.agentmercantile.com/v1/portfolio-preflight
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.
https://api.agentmercantile.com/v1/productive-venue-snapshot
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.
https://api.agentmercantile.com/v1/transaction-gas-preflight
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.
https://api.agentmercantile.com/v1/url-context
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.
https://api.agentmercantile.com/v1/web-change-snapshot
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.
https://api.agentmercantile.com/v1/x402-presign-handoff
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.
https://api.agentmercantile.com/v1/x402-service-change-snapshot
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.
