All projects matching “transactions”

Explorer for x402 activity: servers, transactions and facilitators.

Settlement-backed machine evidence for autonomous agents. Returns a signed-payment transaction reference and machine-readable proof after exact USDC settlement.

Get $X402LAND tokens via the base x420 protocol with zero gas fees.Note: 1 transaction = 1000 $X402LAND

Address Watch for 30 days: every confirmed transaction paying to or spending from one Bitcoin address, in a private feed (web, JSON, RSS) and as phone push (ntfy). Optional feed=<id> adds the address to, or extends it in, an existing feed. Returns the feed links.

Fast wallet lookup on Base or BNB Chain (?chain=bsc): OFAC sanctions, first seen, last active, sent transactions, native and USDC balances, and the first funder (sanctioned, exchange or hub, or funder of many wallets). Verdict hold / review / no_flags with one reason; a never-used Base address planted as an address-poisoning decoy gets hold; a payer that is a px402 privacy pool relayer gets review

Verify that a Base mainnet transaction paid at least N USDC to an address (optionally from a given sender, with K confirmations). Returns matched transfer, block time and confirmations. Read-only.

Spot FX: one ECB reference conversion, plain text. Conversion is calculated from the ECB reference rate (amount × rate). Indicative only. Not a trade quote, not for settlement. Informational only / not for transaction use. Source: ECB statistics. These reference rates are free at https://www.ecb.europa.eu (and via Frankfurter). Not sold or endorsed by the ECB.

Post a message to the board — a public, permanent, paid message wall. Every message costs $0.001 USDC, making economic proof-of-intent the spam filter. Messages are public, timestamped, and attributed to the paying wallet's transaction hash.

Use this before signing a transaction for a Solana program: who can change its code (single key, Squads multisig with threshold and time lock, DAO, or immutable), when it last changed, verified build, security.txt. Instant, per request.

Parses a bank statement (CSV from any bank, camt.052/053/054, MT940, OFX/QFX, QIF) into normalized JSON: accounts, balances and signed transactions with ISO dates, counterparty, reference and OCR number. Deterministic, no AI, nothing stored. JSON body up to 1000 KB. Failed calls (4xx/5xx) are not settled.

Run before setting a priority fee. Gives the price in the exact unit Compute Budget expects (micro-lamports per compute unit) and the total cost in SOL, so a unit mix-up never overpays. Turns recent on-chain priority fees into three prices: cheap, normal and fast. Pass your transaction to get its compute limit and exact cost at each price.

Use before an AI agent pays a vendor or counterparty. Returns an action-oriented allow/review/block evidence preflight: legal-entity resolution, potential sanctions signals, RDAP domain evidence and company-domain consistency. x402 payment safety decision support only; not legal or transaction approval.

Read-only Solana financial-action firewall: decode and simulate an unsigned transaction, bind observed effects to declared intent and policy, and return a signed PASS/FAIL/REVIEW receipt

Spot FX: one ECB reference conversion, plain text. Conversion is calculated from the ECB reference rate (amount × rate). Indicative only. Not a trade quote, not for settlement. Informational only / not for transaction use. Source: ECB statistics. These reference rates are free at https://www.ecb.europa.eu (and via Frankfurter). Not sold or endorsed by the ECB.

On-chain snapshot for a Base address: contract vs EOA, transaction count, ETH balance, USDC balance, risk flags, and a simple recommendation (safe_to_pay | review | avoid). Use before your agent sends USDC to an unknown payTo wallet.

Simulate and inspect an unsigned Base transaction for approvals, privileged selectors, reverts and target-code anomalies.

Verify a Base (mainnet, default) or Base Sepolia transaction is a successful, confirmed transfer of native Circle USDC (not a look-alike token) to an expected recipient for an exact or minimum amount. Checks receipt status, canonical block, confirmations, optional payer, notBefore/maxAge windows; returns verdict valid|invalid|pending|not_found with machine-readable reasons and the matched Transfer

Quorum-verified Base USDC receipt across two of three public RPC sources: transaction status, recipient, amount and confirmations
