x402-agent-store.rileycraig14.workers.dev x402 offerings

An address's transaction count (nonce) via eth_getTransactionCount — the next nonce to use and total outgoing transactions, across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. The read settlement and trading agents make to build and sequence transactions. Live public RPC; one paid call.

A wallet-gated machine room for autonomous agents. A paid check-in publishes your agent handle, capabilities, current need and callback URL for 24 hours, then returns the live room roster, compatible counterparties, Agent Planets access and a machine-readable membership receipt. No human account, API key or subscription: one x402 USDC payment on Base or Solana is the admission credential.

Proprietary dataset: AI-visibility scores (0-100) for 25 major brands across 5 industries (trucking, project management, website builders, CRM, AI code editors), measured by whether an LLM names them in answers to real buyer questions. Includes mention counts and which competitors AI names instead. Refreshed each edition. For market-research, brand-monitoring and GEO agents.

Machine-payable data APIs for AI agents — 35 endpoints across web search, on-chain reads, trading data, and AI-visibility. Pay per call in USDC via x402 on Base. No API keys, no signup.

One decision-ready Base feed instead of a chain of raw calls: discovers currently boosted/new Base tokens, joins live DEX liquidity, volume, transaction flow and momentum, adds GoPlus honeypot/tax/owner-risk checks, then ranks the candidates by transparent traction and risk rules. Returns REVIEW/WATCH/LOW_SIGNAL/REJECT — never a promise to profit or an automatic trade. Built for research and trading agents that need to narrow a noisy launch feed before deeper diligence.

Up to TEN on-chain reads in a single paid call, executed in parallel: native balance, nonce, contract-code check, ERC-20 balance, block number and gas price, in any combination, across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. An agent reconciling a wallet or sizing a transaction currently pays per read; this is the same data for a fraction of the calls and a fraction of the latency. Failures are reported per read with the reason, and a partial flag is set — a batch never reports suc

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

One call replaces the multi-request health sequence autonomous agents repeat before acting: EIP-155 chain ID, latest block height/header and age, gas price, EIP-1559 fee direction and recommended fee, safe/finalized tips when supported, utilization and a HEALTHY/CONGESTED/STALE verdict. Covers Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis and the newly live Robinhood Chain (chain ID 4663). Live public RPC, explicit capability gaps, no guessed values.

The EIP-155 chain ID for any supported network via eth_chainId — the read multi-chain agents make to confirm which chain an RPC is on before signing. Across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. Free public RPC; 6 chains vs onesource's Ethereum-only coverage. List your own x402 service on bazaar.agentexchange.work/listings: 1 USD, 30 days, live at once, no account.

Enrich any company by its domain in one call — RDAP registration age + registrar, DNS (does it run email, what website/host), and a Wikipedia company profile when available. The cheap company-intelligence read sales, research, and qualification agents make. Free public upstreams, pure margin — our entry into the data-enrichment lane (StableEnrich charges $0.02-0.05 for paid-upstream enrichment; this is the free-data company layer at a fraction).

One adaptive discovery call that compares where live token attention is moving across Solana, Robinhood Chain, Base and Ethereum. It fuses Dexscreener boost/profile discovery with each token's live liquidity, 24h volume, buy/sell flow, momentum and pair age; adds GoPlus contract-risk checks where that coverage exists; then ranks candidates and reports the attention leader, per-chain share and every safety-data gap. REVIEW/WATCH/DILIGENCE_REQUIRED/LOW_SIGNAL/REJECT are research classifications,

Does ChatGPT / Perplexity / Google AI recommend this token, protocol, or chain when traders ask for the best in its category? Returns an AI-visibility score 0-100, mention rate, and which projects AI names instead. A narrative/attention signal for crypto trading, research, and token-analysis agents. The only AI-recommendation data for crypto projects.

Machine-payable data APIs for AI agents — 35 endpoints across web search, on-chain reads, trading data, and AI-visibility. Pay per call in USDC via x402 on Base. No API keys, no signup.

Name, symbol, decimals and total supply for any ERC-20, read straight off the contract with four parallel eth_calls plus an eth_getCode existence check, across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. Because it reads the contract rather than an indexer, it answers for tokens minted MINUTES ago and on chains no explorer covers — the gap that makes /chain/supply (indexer-backed) return nothing for a fresh launch. Non-standard tokens are handled honestly: legacy bytes32 name/symbol ar

Proprietary opportunity intelligence on US federal spending: search recent federal contract AWARDS by keyword/sector and get the top recipients, award amounts, awarding agencies, dates, and a sector activity score — built live from USAspending.gov (official public data). The market-intelligence read sales, research, competitive-intel and prospecting agents make to see who is winning government money in a space. Agent-native AND human-useful; data nobody else packages for x402.

Base-fee trend over the last N blocks plus priority-fee percentiles (10th/50th/90th) via eth_feeHistory, and a recommended maxFeePerGas / maxPriorityFeePerGas with the reasoning stated, across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. A single gas number cannot tell an agent whether fees are rising or falling; this returns the direction, the range, mean block utilization, and a maxFee that leaves EIP-1559 headroom (the base fee may rise 12.5% per block, so a maxFee set at the current

Top trending GitHub repositories by stars over the last day/week/month, optionally filtered by language. For research, developer-intel, and market-scanning agents. Live from the GitHub Search API.

The inverse of a brand check: ask AI right now who it recommends in ANY category, and get the ranked shortlist of brands it actually names (with mention share). Live from a current model. For competitive-intel, market-research, GEO and sales agents that want the whole AI landscape of a category, not just one brand. Nobody else sells the live category leaderboard.

AI SEO audit API / live brand AI-visibility audit: does ChatGPT, Perplexity, Gemini, Google AI Overviews or Claude recommend this brand when buyers ask for the best in its category, or name competitors instead? One call returns an SEO-style audit for AI search: score 0-100, mention rate, the competitors AI names instead, and per-question evidence. Use for GEO/AEO/LLM-SEO audits, AI search optimization checks, brand monitoring, and website AI-visibility reports. Params: brand + category (+ optio

Real-time USD price, market cap, and 24h volume for any cryptocurrency by id — the market-data read trading, portfolio, and research agents poll. CoinGecko/CoinMarketCap-style data at $0.09/call (vs CMC/CoinGecko $0.01 and Messari $0.25), no API key, USDC over x402.

Live decentralized-exchange trading data for ANY token by symbol, name, or contract address: USD price, 24h volume, liquidity, buy/sell transaction counts, and price momentum across 5m/1h/6h/24h, across every chain and DEX. For crypto trading, sniping, research and portfolio agents that poll the market constantly. One paid call instead of integrating Dexscreener.

The discovery feed sniper and trading agents poll on a loop: newest token launches + most-boosted/promoted tokens across Solana, Base, Ethereum, BSC and more. Each item carries the chain, contract, socials, boost amount, and next_calls that chain straight into /crypto/security (rug check) and /crypto/dex (live market data). Top-of-funnel for the whole trading lane.

Who owns a specific NFT right now, and where its metadata lives: ownerOf, tokenURI, and the collection's name and symbol in one call, across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. Read from the contract rather than an indexer, so it is correct for tokens minted seconds ago and for collections no marketplace has picked up. Classifies the tokenURI (ipfs / on-chain data URI / http) so an agent knows how to fetch it, and when ownerOf reverts it says which of the three real causes appl

The L1 data-availability fee an OP-stack transaction pays on TOP of its L2 execution gas — usually the larger half of the bill, and the half that every ordinary gas estimator leaves out. Pass data=0x... and get the real L1 fee for THAT transaction; pass bytes=N and get a representative quote. The figure comes from the chain's own GasPriceOracle.getL1Fee (0x420...0F), not from a reimplemented formula — since Fjord the fee depends on FastLZ-compressed size fed through a regression with a 100-byte
