Server instructions

18 pay-per-call services for agents: on-chain anchoring and attestation, wallet sanctions screening, Web3 data (tx/calldata decode, ENS/SNS, token prices), x402 spend accounting, content analysis, and verifiable randomness. No API key and no account. Every tool is priced in its description ($0.001-$1.77) and settles per call in USDC on Base or Solana via x402. Calling a tool without payment is not an error you should give up on: the result comes back with isError=true and a structuredContent.accepts array — that is the x402 challenge. Sign one of those payment options and retry the identical tools/call with a PAYMENT-SIGNATURE header (x402 V2; the V1 X-PAYMENT spelling is also accepted). Read-only tools are marked with annotations.readOnlyHint.

Known tools 18

anchor_hash

Anchor a 32-byte hash to Base + Solana mainnet in parallel.

Inferred read-only

attest_decision

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.

Inferred read-only

aura_read

Read the aura of anything — color, tier (S/A/B/C/D/F), score 0-9999, description.

Inferred read-only

decode_calldata

Decode raw EVM calldata into function name + typed parameters via openchain.xyz + eth_abi.

Inferred read-only

decode_tx

Structured decode of any mainnet transaction by hash.

Inferred read-only

grade_target

Academic letter grade with red-pen marginalia for anything.

Inferred read-only

intel_wallet

Unified wallet intelligence bundle.

Inferred read-only

investigate_wallet

Agent-driven wallet due diligence — multi-step investigation, signed markdown report + JSON sidecar, dual-chain anchored.

Inferred read-only

ledger_report

Signed + dual-chain-anchored x402 expense report (markdown + CSV, async job).

Inferred read-only

ledger_summary

x402 spend accounting for any Base wallet — totals + per-service breakdown reconstructed from chain data.

Inferred read-only

oracle_verdict

Yes/no oracle with dual-chain anchored verdict (Base + Solana).

Inferred read-only

Witty roast of any target — wallet, tweet, idea, code, anything.

Inferred read-only

roll_random

Verifiable RNG — cryptographically-random integer(s) signed by the treasury key.

Inferred read-only

screen_wallet

Wallet risk pre-flight for agent payments: OFAC SDN sanctions plus address-reputation (drainer, phishing, mixer, laundering) resolved to an allow/review/block recommendation with per-signal detail.

Inferred read-only
