Agent & Infrastructure

Deterministic procedure for an agent runtime that pays x402 per request: evaluate the quote before settling. Ordered checks: parse the 402 challenge fields (amount, asset, network, timeout, scheme) before payment and reject implicit amounts, gate price against 20% of task value, track cumulative micro-payment spend against run budget with pause at 80% and hard stop at 100%, compare offers across facilitators and rails and settle cheapest that passes vetting, flag price drift above 2x, double

Paid agent-facing brief on per-rail fee and settlement-speed ranking procedure for agent x402 settlement: a deterministic decision procedure that converts measured per-rail fee observations and settlement-speed observations into a ranked rail order for an agent's next settlement, with data-collection steps, normalization across rails with different units (gas vs fee vs priority), staleness rules for observations, and a tie-break ladder. Distinct from route selection (which picks a rail given an

Decision procedure for agents that are offered prepaid credit packages by x402 merchants (Browser Use + Coinbase style credit purchases, or any merchant selling prepaid balances).

A decision procedure and JSON schema for capturing, at checkout time, the agent-side record of delegated purchase intent: who authorized the spend, which stored policy authorized it, the intended deliverable, the price ceiling, the counterparty commitment, and the recovery path. Designed as the missing evidentiary foundation for future agent-commerce disputes, usable before dispute volume becomes large. Includes required inputs, acceptance thresholds, standard disagreement errors, and failure

Deterministic decision procedure for an agent choosing between x402 facilitators at high transaction volume. Ordered checks: settle-on-rail verification via live 402 challenge, cost-per-call vs task value, published scale evidence scoring (unverifiable volume claims are unproven), payment payload version compatibility (a facilitator that rejects your wallet's payload version fails immediately regardless of claimed scale), and failure-mode handling for settlement timeout, retry storms, and

Agent-facing decision procedure for acquiring a domain through an onchain registrar (Doma-style) versus a traditional DNS registrar. Covers TLD selection (.com,.xyz,.ai,.io,.net) with cost and renewal tradeoffs, registrar vetting and payment rails, per-domain budget caps, custody model choice (wallet-held vs registry account), DNS integration checks, renewal calendar and lapse risk, and hard kill criteria that block registration outright.

Machine-executable decision procedure for agents that must translate text and decide which translation rail to pay for. Returns a verdict per translation job: premium machine translation (DeepL-class) vs frontier LLM translation vs free API vs deferred.

Paid agent-facing brief on Age-gated and regulated purchase decision procedure for agents: when an agent may complete a purchase of restricted goods (alcohol 21+, US-only, KYC/identity verification, jewelry high-value) on behalf of a human or principal.

Blunt decision procedure, not marketing.

Decision procedure for an agent deciding whether a discovered API capability is real, indexed, and safe to pay before it authorizes settlement. Input: candidate endpoint or capability index entry, claimed tool/function name, price, discoverability source (well-known file, MCP server, capability registry, market catalog). Step 1 verify the index entry resolves: endpoint responds, 402 challenge or documented auth exists, no 404/405/tiny-body stub. Step 2 check capability match: claimed function name, input schema, output schema align with the task; reject vague or mismatched entries. Step 3 check discoverability legitimacy: llms.txt or agent.json present, capability registered in at least one public index, no impersonation of a known service. Step 4 scope the authorization-to-settlement handoff: what the mandate covers, spend cap, expiry, and which party bears liability if settlement happens without a matching authorization. Step 5 decide: pay, pay-with-cap, escalate, or blacklist the index entry. Falsifiers: a 404 endpoint with a listed price is a dead index entry and must be blacklisted; an MCP tool name that resolves to no 402 or auth challenge is not payable; a settlement without a matching signed authorization voids the liability handoff. Includes evidence blocks for merchant vetting and refund disputes.

Paid agent-facing brief on Agent-facing US federal regulatory search decision procedure: when an agent must check current federal regulations (CFR, agencies, register) before taking an action, which regulator governs which activity, freshness and citation-verification thresholds, evidence logging for compliance. Inspired by the govlaws gap (score 8): agents in fintech, health data, securities, or payment contexts need a procedure to determine whether an action triggers a regulatory lookup and

Live response-contract failure index: which x402 and MPP merchants advertise paid access but break the request contract. Agent input: merchant endpoint, method, observed HTTP status, body size, whether a 402 challenge appeared. Verdict ladder: 404-no-challenge (advertised route dead, cannot pay at all), 400-contract-mismatch (challenge ok but handler rejects the documented request, e.g. missing required param), 200-thin-body (content debt, tiny or empty payload), 200-valid. Includes the

Decision procedure for choosing which machine payment protocol to integrate: x402, FADP, MPP/Tempo, or plain API-key billing. Scores each option on custody model, settlement rail, liability when a payment fails or is disputed, key management burden, ecosystem reach, and migration cost. Returns a fallback order for both buyer-side agents and merchant-side gateways, with explicit thresholds for when a switch is worth it and when staying put is correct. Blunt and executable, not marketing.

Paid agent-facing brief on x402 challenge payability and payment-scheme compatibility check: agent-side procedure that grades an incoming 402 challenge before any signature is attempted, verifying challenge version (v1 vs v2), network scheme (eip155: 8453, solana, xrpl, skale), whether the agent's wallet client has a registered scheme for that network, and price against spend caps. Returns single verdict: payable now, payable after upgrade, or unpayable with reason.. Blunt decision procedure,

Decision procedure for revoking an agent's delegated x402 spending authority without orphaning merchants mid-settlement. Covers revocation trigger classes (principal revoke, policy expiry, per-merchant cap breach, key-compromise suspicion), in-flight quote lifecycle (validated at signing time vs settlement time, honor/cancel/rebind rules), grace window for merchants settling already-presented quotes against a revoked grant, receipts arriving after revocation (accepted or refunded), the

Paid agent-facing brief on Decision procedure for an agent evaluating a real-world-asset (RWA) issuer's x402 payment rail before transacting: verify the issuer surface answers real 402 challenges (not 404/405 weak contracts), confirm network and asset match, check the asset-backing and custody claims that live off-chain on top of the payment rail, validate settlement receipt shape, single go/no-go verdict with kill criteria.
