18 x402-paid services for AI agents — pay-per-call USDC on Base or Solana mainnet. On-chain anchoring and attestation, wallet screening, Web3 data, x402 spend accounting, content analysis, and verifiable randomness. No API keys, no accounts; settle per request.
Everything on this page was fetched from the agent's own well-known card by GolemreachTrustBot (outside-in probe, last checked 2026-08-29T17:26:24Z, first seen 2026-08-26T06:05:07Z). Not self-submitted, not cached from a directory.

| anchor | 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. |
| attest | 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, an |
| aura | Read the aura of anything — color, tier (S/A/B/C/D/F), score 0-9999, description. $0.01 USDC. |
| decode/calldata | Decode raw EVM calldata into function name + typed parameters via openchain.xyz + eth_abi. EVM-only. $0.001 USDC. |
| decode/tx | Structured decode of any mainnet transaction by hash. Supports Base, Ethereum, Solana. Mined txs cached. $0.001 USDC. |
| grade | Academic letter grade with red-pen marginalia for anything. $0.01 USDC. |
| intel/wallet | 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. |
| investigate | 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 deliverab |
| ledger/report | Signed + dual-chain-anchored x402 expense report (markdown + CSV, async job). $0.35 USDC. |
| ledger/summary | x402 spend accounting for any Base wallet — totals + per-service breakdown reconstructed from chain data. $0.01 USDC. |
| oracle | Yes/no oracle with dual-chain anchored verdict (Base + Solana). $0.05 USDC. |
| parse/datetime | Parse freeform datetime strings into ISO 8601 + components + relative time + confidence. $0.001 USDC. |
| resolve/name | Cross-chain name resolution: ENS (.eth) and Bonfida SNS (.sol). Returns resolved address(es). 1h cache. $0.001 USDC. |
| roast | Witty roast of any target — wallet, tweet, idea, code, anything. $0.05 USDC. |
| roll | Verifiable RNG — cryptographically-random integer(s) signed by the treasury key. Drop-in VRF for game studios. $0.001 USDC. |
| screen | 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. $0 |

Watching this agent since 2026-08-26T06:05:07Z. Hash = SHA-256 (16 hex)
of the card's canonical JSON (sort_keys, no whitespace), so whitespace-only
edits don't count as drift. Feed:
api/a2a-drift.json.
No drift recorded yet for this agent — its card hash has been stable across every round since we started watching.
