What this server can do

45 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

agent_readiness_audit(domain)

Audit any domain for agent-economy readiness: checks the six discovery surfaces agents actually read (x402 discovery doc, A2A agent card, OpenAPI, llms.txt, robots.txt, MCP manifest), validates their key fields, and returns a weighted 0-100 score with concrete recommendations for what to publish next. $1.00/call via x402. Required: domain.

answer_with_sources(question)

Answer a question from current web research and return a concise answer with its cited sources. $0.65/call via x402. Required: question.

base_block_number

Current Base mainnet (eip155:8453) block height, fetched live with automatic RPC failover — use as a chain-liveness anchor or a confirmation baseline. $0.002/call via x402.

base_gas_price

Live Base mainnet gas pricing: eth_gasPrice plus the latest block baseFeePerGas (EIP-1559), returned in both wei and gwei with the block height sampled. $0.002/call via x402.

base_tx_status(hash)

Live USDC balance of a Base mainnet address — balanceOf on the canonical Base USDC contract, returned both atomic (6-decimal units) and as a formatted USDC string. $0.003/call via x402. Required: address.

base_usdc_transfer_check(tx)

Verify a Base mainnet tx hash actually moved USDC: decodes every USDC Transfer log in the receipt (from, to, amount) and answers settled true/false — the check an x402 seller runs before trusting a payment reference. $0.004/call via x402. Required: tx.

bazaar_listing_lint(resource)

Lint an x402 Bazaar listing before buying or before publishing your own: 0-100 quality score combining a live probe of the resource (valid 402? description? output schema? category? above the CDP price floor?) with its day-by-day snapshot history (price churn, delisting). $0.01/call via x402. Required: resource.

bazaar_market_report

The full state of the x402 Bazaar in one JSON dossier — marketplace totals, price distribution and bands, network split, top services and sellers, new entrants, day-over-day movers, and how many listings have real repeat buyers. Built from daily full-catalogue snapshots. $0.50/call via x402.

Full x402 Bazaar market pulse for the latest completed daily snapshot: catalogue totals, top services by call volume, new listings and networks. $0.002/call via x402.
