Basename lookup: resolve a Base name such as jesse.base.eth to its wallet address, with avatar and profile text records. Input: name

Simulate a read-only contract call on Base (eth_call) without sending a transaction: returns the raw result or the revert reason. Use it to dry-run a call before signing

Pay-per-request governance APIs for AI agents using x402. Check budgets, log payments, classify invoices, and generate audit-ready spending records. Built for autonomous agents, USDC/Base payments, and JPY/JPYC reporting workflows. Also supports duplicate lookup prevention and market data budget control for AI agents using paid data APIs.

The trust layer for AI-agent payments on Base. One live x402 endpoint that certifies agents pay safely, scores any wallet's payment risk, and escrows agent deals with automated on-chain arbitration. Real USDC, verifiable on-chain.

Pre-flight check before a swap or transfer: ERC-20 allowance, balance, decimals and symbol in one call, read live from the chain at the latest block. Pass an amount and get a straight would_succeed verdict with the blocking reason and the action needed. Base, Ethereum, Arbitrum, Optimism, Polygon. A missing approval burns the gas of a failed transaction - this call costs a fraction of that.

What happened to my transaction? Status, block, gas used, fee paid - and if it failed, the revert reason in plain text, recovered by replaying the call against its block. The receipt alone does not carry that reason.

One-shot agent grounding snapshot in 200-400ms — factor breadth, top/bottom composite assets with regime, recent signal aggregation, platform counts, and pipeline status. Call before any market reasoning task. Runs across 200+ digital assets — BTC, ETH, SOL, top-cap + long-tail coverage.

Volume-anomaly observations across newly created BSC pools, from a 15-minute monitoring sweep: pools whose hourly volume spiked vs the prior hour (floor $1,000 and 100x), with pool name, hourly volume, spike ratio, price move and source link. Machine-readable monitoring feed for agents tracking early on-chain activity. Observation data only — thresholds uncalibrated; not signals, not financial advice. Refreshed every 15 minutes; data age disclosed in every response.

Verified market-moving events for crypto agents: headlines categorized (liquidations, macro, regulation and more) and tagged to BTC/ETH, each with source, publisher, timestamp, original link, and a trust tier distinguishing primary official sources from aggregated headlines. Filter by symbol, category, and count. Fresh every 15 minutes.

Multi-timeframe market state for BTCUSDT, ETHUSDT, SOLUSDT, XRPUSDT & DOGEUSDT USD-M perpetual futures in one call: mark & index price, funding rate, open interest change, taker buy share, per-timeframe (4h/1h/15m) EMA-20/50, RSI-14, ATR and prior 20-bar high/low. Structured for trading agents needing clean market context. Descriptive data only — not financial advice. Refreshed every 15 min; data age disclosed in every response.

Send one SMS to a mobile number, paid per message in USDC with x402. Use it when an agent must notify a person by text. The 402 quotes the exact price for the destination and message length. No account and no API key: any wallet that pays sends in one call. An opt-out link is appended to the message, and numbers that opted out are refused. Returns an order; poll GET /v1/orders/{id} for delivery status.

Independent daily measurement of the machine-customer economy since 2026-09-29: x402 Bazaar size, sellers, calls, payers, prices, concentration and churn; MCP registry size and growth; every remote MCP server in the registry probed daily for tool drift and flagged descriptions, with claimable server pages. Skills are plain HTTP GET endpoints documented in llms.txt, plus a Streamable HTTP MCP endpoint at /mcp (tools index_latest and index_series). There is no A2A JSON-RPC endpoint. Free: summary, series, census, per-server data, CSV dumps, RSS, MCP. Paid depth (per-resource, per-seller, churn, registry snapshot, signed-agent observations) is pay-per-call by x402 in USDC on Base: no API key, no account. Data license CC BY 4.0.

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.
