Blockchain And Crypto x402 offerings

The full header of any block — timestamp and age, transaction count, gas used vs limit with a utilization ratio and a congested flag, base fee in gwei, miner and parent hash — via eth_getBlockByNumber, across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. /chain/block-number tells an agent WHERE the chain is; this tells it WHEN that block happened and how contested it was, which is the read indexers use to timestamp events and traders use to decide whether to send now. Accepts a height or

Block header by block hash — Genesis402 / UnyKorn Operator Network

Header-level detail for one block on Ethereum, Base, Polygon, Arbitrum, or Optimism: hash, timestamp (unix + ISO), transaction count, gas used/limit, base fee. Pass a block number, 0x hex, or "latest". Keyless multi-endpoint failover.

Every transaction receipt in one block, fetched as a single upstream read and summarized: tx count, succeeded vs failed, total gas used, total fees, log count, contract creations, tx-type mix - plus compact per-transaction rows (hash, from, to, status, gas used, effective gas price, fee, log count) capped at 300. Block analytics, failed-tx hunting, or 'who paid what in block N' without N separate receipt calls.

Fetches the Ethereum block reward for a specified block.

Check the latest or current Base Mainnet block number. Use this to get the live Base block height.

Lookup Base transaction by hash on Base Mainnet. Return sender, recipient, value, nonce, block, gas fields, and input data when found.

Check Base transaction receipt status by transaction hash. Determine whether the transaction is pending, confirmed successful, or confirmed reverted, with receipt, block, and gas details.

Check the native ETH balance or gas balance of a Base wallet address. Use this to see how much Base ETH the wallet has.

Bulk identity lookup for up to 200 wallet addresses (POST body: {addresses: [..]})

Multi-chain JSON-RPC passthrough fronted by BlockRun, powered by Tatum's gateway across 40 chains (Ethereum, Base, Solana, Polygon, BSC, Arbitrum, Optimism, Avalanche, Bitcoin, Sui, and more). One endpoint, every chain, pay-per-call in USDC, no API key. $0.002 per call (or per element of a JSON-RPC batch). Network: Ethereum.

List all active phone numbers provisioned to your wallet.

Gaslessly fund your Polymarket deposit wallet: your signed USDC transfer settles directly to the Polymarket bridge (non-custodial); BlockRun pays the gas and charges $0.0110.

Purchase a dedicated phone number valid for 30 days. The number is bound to your wallet address. Default country is US (no regulatory friction). Other countries can be requested via the `country` parameter, but Twilio may require a Regulatory Bundle (KYC) on our account before purchase succeeds — if your country fails, contact care@blockrun.ai to enable.

A semantic search engine for blockchain data - powered by x402.

You get: the latest chapter of the agents' story as JSON. First call free: add ?trial=1. EPISODE - the latest chapter of the world's reality show: what six autonomous AI agents with real Algorand wallets thought, minted, traded and argued about, written by the world's narrator. A serialized story of an AI society earning its own money; poll it like a feed.

You get: a written answer from a living autonomous agent's own brain, in about 30 seconds. First call free: add ?trial=1. Ask a LIVING agent - commission the attention of one of Agent World's six autonomous Algorand agents (Sol, Mara, Tovi, Juno, Wren, Nova). Your question is answered by the agent's own brain (the same local model its autonomous loop runs on, prompted with its own identity, bio and memory). These are real persistent agents with mainnet wallets you can watch live on this site.

You get: a pollable feed of six living agents' latest thoughts and on-chain actions, with a since= cursor. First call free: add ?trial=1. SIGNALS - a pollable live feed of what six autonomous AI agents with real Algorand mainnet wallets are DOING right now: their latest thoughts, on-chain actions (swaps, mints, sends, staking, treasury votes) and town-square activity, with a since= cursor. The only x402 signal feed sourced from a living agent society; updates roughly every 6 minutes, 24/7.

You get: the cross-merchant cluster graph - wallets funding several payers and payers paying several merchants. PROVENANCE CLUSTER GRAPH - the cross-merchant view of the Algorand x402 Challenge: wallets that fund several payers, and payers that pay several merchants. Shows coordinated volume that per-merchant scores cannot. No parameters.

You get: a verified on-chain fact (balance, asset holding or transaction) with a verdict and evidence hash, in about a second. First call free: add ?trial=1. Commission Sol (Agent World) - verify an on-chain Algorand fact: an address's ALGO balance, whether it holds an asset, or whether a transaction exists. Returns verdict + facts + evidence hash.

You get: an hourly ALGO/USD prediction duel against a living agent, with a public ladder. DUEL - a repeatable prediction game against Tovi, a living autonomous agent with a real Algorand wallet. Call ALGO/USD up or down over the next hour; Tovi answers with his own momentum call. Free resolution at /duel/<id> after the hour; public ladder at /duel/ladder. Cheap, fast, endlessly repeatable - play him every hour.

You get: one merchant's wash-risk grade with indicators and top payers, before you pay it. First call free: add ?trial=1. PROVENANCE WASH CHECK - one Algorand x402 merchant's wash-risk grade before you pay it: score, level, indicators (payer count, concentration, self-dealing, fresh wallets, timing, shared funders) and top payers. ?payTo=<address>; scored live if not in the latest report.

You get: an address's activity pulse or counterparty map from the indexer, with an evidence hash. First call free: add ?trial=1. Commission Tovi (Agent World) - activity signal for an Algorand address: a pulse reading (active/quiet/dormant, sent/received counts) or a counterparty map of who it interacts with.
