▸ GET /x402/agent-spendN/A
Bookkeeping statement for an AI agent's own spending: reads every USDC payment of a wallet from Base, converts each to EUR at the ECB rate of the payment date, groups by payee, adds the VAT treatment (reverse charge, Art. 44/196) and returns a bookkeeping-ready statement plus CSV export. Agent micro-payments become auditable. $0.1 · — · Base ▸ POST /x402/einvoiceN/A

Each hit states its list, programme, reference and the list date. Optional lists=eu,un,uk. $0.01 · — · Base ▸ GET /x402/historyN/A
Historical time series that no upstream provider sells. They sell the current value; we archive every value we buy, so the series over days and weeks becomes ours alone - it cannot be copied because a competitor lacks the past.

The scoring rule and point count are disclosed in every response; a short series says so honestly. $0.008 · — · Base ▸ POST /x402/chatN/A

Computed crypto-market indicators, not a data relay. We buy raw feeds from several upstream x402 providers and compute our own market-regime reading. The scoring rule is disclosed in every response, so the result is reproducible. Products: market_brief, yield, gas.

For XRechnung, ZUGFeRD, Peppol BIS and OSS workflows. $0.005 · — · Base ▸ GET /x402/socialN/A
Search recent public posts across OPEN social networks - Bluesky, Hacker News and Mastodon - in one call: author, text, time, engagement, link. Failing sources are named in the answer, never silently dropped. Twitter/X and TikTok are deliberately out of scope: their terms forbid scraping. Query: q, limit. $0.002 per call, signed receipt included. $0.002 · — · Base ▸ GET /x402/tokenN/A
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.

A missing approval burns the gas of a failed transaction - this call costs a fraction of that. $0.002 · — · Base ▸ GET /x402/txN/A
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. $0.002 · — · Base 25 50 100
