x402-paid agent tools: 18 over HTTP, 14 over stdio. USDC per call, no API key.
Scored across 18 tools
Most tools target clearly distinct actions/resources (anchoring, decoding, name resolution, price, rng, novelty generators). The wallet cluster (intel_wallet, investigate_wallet, screen_wallet, ledger_summary) and the two decoders (decode_calldata vs decode_tx) partially overlap, but descriptions scope them by depth, output, and input type. No two tools appear to do the same thing outright.
Everything is uniformly lowercase snake_case with no case/style chaos. The pattern mixes verb_noun (anchor_hash, decode_tx, screen_wallet) with noun_noun (token_price, oracle_verdict, ledger_report) and one reversed noun_verb (aura_read), which is a minor deviation rather than an inconsistent convention.
18 tools is on the heavier side, but this server is explicitly a paid microservice aggregator where each tool is a distinct billable product, so most earn their place. A few novelty entries (aura_read, roast_target, grade_target) stretch the scope but don't create redundancy.
Sub-domains are reasonably covered: anchoring (anchor_hash, attest_decision, oracle_verdict), wallet intel (intel/investigate/screen/ledger_summary), decoding (calldata/tx), plus utilities. Minor gaps such as no dedicated anchor-verify or batch tool exist, but each tool is self-contained with no true dead ends.
Anchor a 32-byte hash to Base + Solana mainnet in parallel. Returns both tx URLs as cryptographic proof of when the hash existed. $0.005 USDC.
Inputs: data, hash, note.
Attest a decision over (input_hash, output_hash, decision): sign it yourself, or omit the signature and the treasury signs for you — then dual-chain anchor. Returns the signer, on-chain proof URLs, and a free re-verify URL. $0.010 USDC.
Inputs: decision (required), input_hash (required), output_hash (required), scheme, +2 more.

Inputs: chain (required), tx_hash (required).
Academic letter grade with red-pen marginalia for anything. $0.01 USDC.
Inputs: target (required).
Unified wallet intelligence bundle. ONE call: balances on Base + Ethereum + Solana, USDC, tx counts, ENS/SNS reverse, sanctions verdict. 8-10 parallel sources. $0.005 USDC.
Inputs: wallet (required).
Agent-driven wallet due diligence — multi-step investigation, signed markdown report + JSON sidecar, dual-chain anchored. Async — returns job_id; poll /v1/investigate/status/{job_id} for the deliverable. ETA 5-10 min. $1.77 USDC.
Inputs: address (required).
Signed + dual-chain-anchored x402 expense report (markdown + CSV, async job). $0.35 USDC.
Inputs: wallet (required), to, from, title, +6 more.
x402 spend accounting for any Base wallet — totals + per-service breakdown reconstructed from chain data. $0.01 USDC.
Inputs: wallet (required), to, from, group_by, +3 more.
Yes/no oracle with dual-chain anchored verdict (Base + Solana). $0.05 USDC.
Inputs: question (required).
Parse freeform datetime strings into ISO 8601 + components + relative time + confidence. $0.001 USDC.
