Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

`hash_string`	FREE (no wallet needed): SHA-1/256/384/512 hex digest of a string.
`http_check`	[Web] Liveness/latency pre-flight for a URL: is it up, HTTP status and class, response latency in ms, whether it redirects and where, content-type and server. Costs $0.001. Use before relying on a dependency.
`http_error_explain`	[Web] Explain an HTTP status code: meaning, common causes, fixes, retry guidance. Costs $0.001.
`http_errors_list`	FREE (no wallet needed): index of documented HTTP status codes (use http_error_explain for a paid detailed explanation).

`payment_proof`	[x402] Verify an x402 settlement on Base OR Solana from a tx id (0x hash or base58 signature): confirm it succeeded, decode its USDC transfers, optionally assert payTo/amount - returns a single verdict. Costs $0.003. Choose this when you only need the yes/no did-it-land answer; use settlement_assurance for the full scored report (proof + receipt + optional endpoint audit).
`payment_receipt`	[x402] Formatted settlement receipt for a Base transaction (0x hash) or Solana settlement (base58 signature): timestamp, decoded transfers, explorer link. Costs $0.002. Choose this for a human-readable record; use payment_proof to ASSERT a specific payTo/amount, or settlement_assurance for a full scored verdict.
`public_holiday`	[Dev] Is a date a public holiday in a country (2-letter ISO code)? Returns the holiday name, its types, and the next upcoming holiday. Costs $0.001. Useful for scheduling.
`qr_generate`	[Web] Generate a QR code as SVG (or terminal text with format=text). Costs $0.002.
`quartermaster_info`	Free: catalog, prices, and payment instructions for this server.
`random_numbers`	[Dev] Cryptographically-secure random integers in a range (CSPRNG, unbiased) — real entropy an LLM cannot produce itself. Costs $0.001.
`random_pick`	[Dev] Pick one or several options at random from a caller-supplied list (CSPRNG), optionally without replacement. Costs $0.001.
`regex_test`	[Dev] Test a regular expression against text; returns every match with numbered and named capture groups. Deterministic. Costs $0.001.
`resolve_basename`	Resolve a Basename (.base.eth) to a wallet address on Base. Costs $0.001.
`settlement_assurance`	[x402] FLAGSHIP: from a tx id on Base (0x hash) or Solana (base58 signature), prove a completed x402 payment is real and sound - onchain success, USDC transfer match to an expected wallet/amount, a receipt, and an optional audit of the issuing endpoint - as one 0-100 scored report with a verdict. Costs $0.03. This is the most complete post-payment check; use payment_proof if you only need a plain pass/fail, tx_status for raw status, or x402_audit to grade a seller endpoint by URL (no payment yet).
`summarize_url`	[AI] AI summary of a public webpage (fetch + extract + summarize). length: short\|medium\|long. Costs $0.01.
`text_diff`	[Dev] Compact line-level diff between two texts. Costs $0.001.
`text_stats`	[Dev] Word/sentence counts, reading time, and readability score for text. Costs $0.001.
`tldr_text`	[AI] Summarize raw text you pass in directly (not a URL). length: short\|medium\|long. Costs $0.005. Use summarize_url when you have a URL instead.
`token_price`	[Crypto/Base] USD price for major tokens by symbol or any Base ERC-20 by address. Costs $0.001.
`translate_text`	[AI] AI translation into any target language; source auto-detected. Costs $0.005.
`tx_decode`	[Crypto/Base] Decode a Base transaction's calldata into the function it called and its arguments — ERC-20 transfer/approve and the EIP-3009 transferWithAuthorization used by x402 settlements. Recognizes x402 settlement transactions and formats USDC amounts. Costs $0.003. Use tx_status for pass/fail; use this to see WHAT a transaction did.
`tx_status`	[Crypto/Base] Check a Base transaction: success/reverted/pending, confirmations, gas, explorer link. Costs $0.002. Choose this for a quick raw status; use payment_receipt for decoded transfers, or settlement_assurance to PROVE an x402 payment settled to the right wallet/amount.
`unshorten_url`	[Web] Expand a shortened/redirecting URL: follow the redirect chain and return every hop plus the final destination. Each hop is SSRF-validated. Costs $0.002. Safe way to see where an untrusted link goes.
`usdc_normalize`	Convert USDC amounts between atomic units and human decimals. Costs $0.001.
`wallet_balance`	[Crypto/Base] ETH and USDC (or any ERC-20) balance for an address on Base. Costs $0.001.
`web_extract`	[Web] Extract clean readable text and metadata from a public webpage as structured JSON. Costs $0.005 (USDC via x402).
`x402_audit`	[x402] WORKFLOW: full scored audit of an x402 SELLER endpoint (a URL) in one call - verifies the 402 challenge, payment fields, Bazaar discovery metadata, and the origin's discovery surfaces; returns a 0-100 score, checks with evidence, and recommended fixes. Costs $0.01. Use this to grade an endpoint before trusting/publishing it; use settlement_assurance instead when you already have a transaction hash and want to prove a completed PAYMENT settled correctly.
`x402_discover`	[x402] Search the Coinbase x402 Bazaar for paid resources by natural-language query. Costs $0.001.
`x402_inspect`	[x402] Inspect and lint any x402 paid endpoint: decode the 402 challenge, identify network/asset, flag misconfigurations and Bazaar-readiness. Costs $0.002. Choose this for a quick one-shot decode+lint; use x402_audit for a full 0-100 scored report with origin discovery probes and recommended fixes.
`x402_merchant`	[x402] List all x402 Bazaar resources under a merchant payTo wallet. Costs $0.001.
`x402_router`	START HERE. One tool for anything x402, Base chain, or web/AI: describe your goal in plain English (q) and Quartermaster picks and runs the right underlying tool, returning the answer plus which tool it used. Examples: 'audit https://api.example.com/paid', 'price of eth', 'is 0x… a contract', 'verify settlement 0x…', 'search the bazaar for weather'. Use this when you don't want to choose among the individual tools below. Costs $0.03 (USDC via x402).
`x402_simulate`	[x402] Pre-flight a payment BEFORE you spend: decode an endpoint's 402 challenge, report the cost on every rail (Base and Solana) and the cheapest, and — with an optional payer address — verify the wallet can afford the call on Base. Costs $0.003. Use this before paying an unfamiliar endpoint; use x402_inspect to lint an endpoint you own.
`x402_test_vector`	[x402] Free: example x402 payment-requirement objects with field explanations.

Schemas: list_tools.
