## Tools (as reported by the server, not verified)

- `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', 'verif
- `web\_extract`: \[Web\] Extract clean readable text and metadata from a public webpage as structured JSON. Costs $0.005 \(USDC via x402\).
- `page\_meta`: \[Web\] Get page metadata: title, description, Open Graph, canonical URL, favicon, language. Costs $0.002.

- `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.
- `wallet\_balance`: \[Crypto/Base\] ETH and USDC \(or any ERC-20\) balance for an address on Base. Costs $0.001.

- `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.
- `regex\_test`: \[Dev\] Test a regular expression against text; returns every match with numbered and named capture groups. Deterministic. Costs $0.001.
- `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.
- `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.
- `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.
- `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\_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 x
- `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;
- `embed\_text`: \[AI\] Text embeddings \(1024-dim vector\) for semantic search and RAG. Costs $0.002.
- `extract\_structured`: Structured extraction: JSON Schema plus a URL or raw text in, matching JSON out. Costs $0.005.

Choose this for a human-readable record; use payment\_proof to ASSERT a specific payTo/amount, or settlement\_assurance for a full sc
- `resolve\_basename`: Resolve a Basename \(.base.eth\) to a wallet address on Base. Costs $0.001.
- `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 endpoi
- `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.
