README

legible-check — pay-per-call data tools for AI agents (x402 + MCP)

An MCP server and x402 seller that exposes on-chain data tools an agent can call and pay for per request in USDC on Base. No signup, no API key, no subscription: an unpaid call answers HTTP 402 with the price, the payer signs a USDC authorization, and the tool runs.

MCP endpoint (Streamable HTTP): https://legible-check.ezealfa.workers.dev/mcp
OpenAPI: https://legible-check.ezealfa.workers.dev/openapi.json
Health: https://legible-check.ezealfa.workers.dev/health
Receiving wallet: 0xF3D5de46f73d9f55DFce23F4AAF3Db5505c823c5 (Base)

{  "mcpServers": {    "legible-check": {      "type": "streamable-http",      "url": "https://legible-check.ezealfa.workers.dev/mcp"    }  }}

The server answers JSON-RPC 2.0 over POST /mcp, and also in text/event-stream frames when the client sends Accept: text/event-stream.

Methods: initialize, tools/list, tools/call.

Tools

tool	price (USDC)	what it returns
`evm_block`	0.001	block number, timestamp, base fee, gas used, tx count
`evm_gas`	0.001	gas price split into base and priority fee
`evm_balance`	0.002	native balance in wei and native units
`evm_token_balance`	0.003	ERC20 balance with decimals and symbol
`evm_nonce`	0.002	next transaction nonce
`evm_tx`	0.002	decoded transaction by hash
`evm_tx_status`	0.001	success / reverted / pending with confirmations
`evm_receipt`	0.002	receipt: status, block, gas used, effective gas price
`evm_transfers`	0.003	ERC20 transfers for an address over N blocks
`evm_token_info`	0.002	name, symbol, decimals, total supply
`evm_contract`	0.003	is-contract check, bytecode size, Sourcify ABI
`evm_portfolio`	0.005	native balance + nonce + up to 10 token balances in one call
`evm_decode`	0.003	calldata decoder: selector, signatures, decoded arguments
`crypto_price`	0.001	live prices with 24h change and market cap
`dex_quote`	0.002	DEX pair quotes with liquidity and 24h volume

Chains: base, polygon, arbitrum (pass ?chain= on HTTP, or chain in the tool arguments).

How payment works

Call a tool without payment. The server answers 402 with accepts[]: payTo, amount (atomic USDC, 6 decimals), asset, network (eip155:8453).
Sign an EIP-3009 TransferWithAuthorization for that amount.
Retry the same request with the PAYMENT-SIGNATURE header containing the base64 payload { x402Version: 2, accepted: <requirement>, payload: { type: "eip3009", signature, authorization } }.
The server verifies and settles through the CDP facilitator and returns the data plus a PAYMENT-RESPONSE header with the settlement transaction.

Parameter names are query parameters on HTTP (?address=, ?token=, ?hash=, ?chain=). Unsupported chains are rejected with 400 before any payment is requested.

Why this exists

The agent economy pays per call, but most endpoints are undocumented wrappers with no schema. This server publishes a machine-readable contract: OpenAPI with x-payment-info, an MCP tool list with input schemas, and answers that always state the chain and the block they were read at.

工具

evm_block

Block number on Base: the latest block height, timestamp, age, base fee, gas used and transaction count. Use it when an agent needs the current block number or the chain head. Price: 0.001 USDC per call over x402 on Base.

输入参数chain

evm_gas

Gas price on Base in gwei, split into base fee and priority fee, with the block it was read at. Use it to estimate gas fees before sending a transaction. Price: 0.001 USDC per call over x402 on Base.
