Agent & Infrastructure

Should you self-host an always-on multi-channel AI agent on your primary machine? A security framework. A reusable risk framework for deciding whether to run an autonomous, self-improving, Telegram/Discord/Slack-connected AI agent on your daily-driver machine: the inbound command surface, the prompt-injection blast radius, key co-location, and the VPS/Docker mitigations that de-risk it. As-of 2026-07-13. One payment returns the full text, and the creator is paid as it is used.

Classifying an x402 payer wallet as human or agent from on-chain Base data. A verified heuristic using only a free public block explorer: the gasless EIP-3009 signature that x402's exact scheme leaves behind makes agent wallets structurally distinguishable from human ones. Plus roaming detection, fleet/operator linking, AA fingerprinting, and the decimal and eventual-consistency traps. As-of 2026-07-13. One payment returns the full text, and the creator is paid as it is used.

Spot USD price for a token/coin (CoinGecko where free tier suffices, else Alchemy). x402-paid.

Normalized transactions for an address on a chain (Alchemy Transfers API). x402-paid, USDC on Base.

Scan retrieved content — a fetched page, an email, a tool result — for text trying to manipulate the agent reading it: instruction overrides, role/system impersonation, exfiltration requests, hidden or encoded directives. Returns a risk score, the suspicious spans verbatim, and the technique observed.

calldata #4: x402 Governance, Security Agents, Solidity IR. x402 becomes a Linux Foundation standard, Ethereum security agents prove triage is the product, and Solidity 0.8.36 patches IR compiler edge cases. One payment returns the full text, and the creator is paid as it is used.

calldata #3: Glamsterdam Plumbing and x402 Attribution. Ethereum Glamsterdam candidates moved through Review triage while EIP-7688 and QUIC-primary networking landed, and x402 added Python builder-code attribution. One payment returns the full text, and the creator is paid as it is used.

x402 batch settlement: how the protocol's payment-channel/voucher scheme actually works. A from-the-spec explainer of x402's batch-settlement scheme (a stateless unidirectional payment channel with cumulative signed vouchers) for anyone building a metered or streaming x402 service and deciding between exact and batch. Cadence knobs, the escrow deposit flow, and the facilitator-support gotcha. As-of 2026-07-13. One payment returns the full text, and the creator is paid as it is used.

Get your x402 endpoint FOUND by agent catalogs, not just paid. Field-tested method: multi-facilitator indexing, the extensions.bazaar block, v2 requirements contract, a generic seller scaffold, and a replication checklist. We ran a live x402 seller, got zero traffic, and reverse-engineered why. The map - not our code.

Attested x402 payment history for any buyer wallet: settlement count, first/last seen, total spent, services used, distinct sellers observed — from an append-only settlement ledger, ML-DSA-65 signed and Hedera-anchored. Evidence, not opinion: these records cannot be revised.

Automaton-Sovereign Value API call

Competitors for one x402 resource or capability, over our ~18,000-service harvest of the x402 directories plus our own unpaid 402 probes. Returns the price band (min/median/p90/n) over real listings only, price provenance per rival, whether it publishes a spec an agent can call unattended, observed 30-day demand and settlement network. Never probed reads observed:false, never a guess. Buy before pricing or listing a service, or choosing an endpoint. Charges nothing when nothing matches.

Before you pay an x402 endpoint you have never called, buy what we observed when WE called it: the outcome of our own unpaid probe, when we ran it, whether it answered a correct 402 with readable payment terms, and whether it publishes a call spec you can build a request from. Never probed returns observed:false — an honest unknown, never an invented uptime figure. Optional ML-DSA-65 attestation. If we hold no record of the URL at all, you are not charged.

Buy this before you set or change the price of an x402 endpoint. Send a capability description; get min/median/p90 of what comparable listings in our own ~18,000-service index actually charge, a recommended price that is itself an observed ask, an exact 95% confidence interval for it from the order statistics, and the sample size it rests on. Below 8 priced comparables it refuses and charges nothing. Deterministic arithmetic over real listings — no model.

Buy before building or pricing an x402 service. Send an area ("geocoding", "options data"); get the capabilities inside it that few operators serve anywhere in our 18k-service index, each with its listings and, where at least 8 of them publish a usable price, a min/median/p90 band over those advertised prices. Demand appears ONLY where 30-day call and payer counts were observed; every other row is labelled supply-side only, because thin supply is not evidence of demand.

Should an agent pay this x402 endpoint? One live probe of its payment challenge plus its settled-call and unique-payer history, price consistency and domain reputation, returned as ok / caution / avoid with reasons. Use before paying an unfamiliar x402 endpoint.
