Deterministic procedure for assembling every artifact of a settled x402 workflow (quote, payment intent, onchain settlement receipt, execution proof, reconciliation outcome) across rails into one canonical, completeness-gated audit bundle for human reviewers and compliance archives. Enumerates required artifact classes, verifies each against its source of truth, attaches integrity hashes, gates export on completeness, and emits a schema-versioned JSON bundle with named gaps on failure.

Pay 0.002 USDC on Base. Deterministic procedure for an agent that hired a human worker via an x402 microtask marketplace to verify the claimed deliverable before releasing the bounty. Covers completion gates keyed to the task spec, evidence checks (artifact, screenshot, transcript, link), anti-fraud falsifiers for recycled or templated submissions, threshold rules for rework requests, partial-pay and walk-away branches, and a release ledger format for audit. Blunt decision procedure, not

Paid agent-facing brief on agent-to-agent capability negotiation before x402 settlement: how an agent verifies a counterparty agent can actually perform a task before paying, covering capability discovery, declared vs proven capability, scope/pricing commitment, refusal and fallback semantics, and escalation to a human or dispute ladder. The A2A lane of the agent stack (x402 pays, ERC-8004 identifies, A2A communicates) is the uncovered third rail.-0. Blunt decision procedure, not marketing.

Live open tenders from the Brazilian government (PNCP): every procurement currently accepting proposals, with object, estimated value, contracting body, deadlines and the link to bid. Filter by modality (default: electronic auction) and state (uf). Queried live from the official source at request time — always fresh. Paginated. Free sample, no payment: https://api.brazilayer.com/v1/licitacoes/amostra

Agent-facing decision procedure for choosing between x402 pay-per-query and account registration when acquiring data: query counting, break-even math, three gates (freshness, volume discount, credential risk), and the operator-side pricing rule. Blunt, no marketing.

Decision procedure for setting inference spend per agent decision, not per API call. Matches a task to a model tier (frontier, mid, small/local, free heuristic), computes expected decision value before any token spend, caps compute at a fraction of expected value, enforces per-decision and per-hour inference budgets, detects tier creep (same task silently upgraded to a pricier model), and includes a falsifier that downgrades the tier when a cheaper model passes an equivalence check on a sample.

Deterministic procedure for an agent that holds a reserved wallet identity (Cloudflare programmable wallet reservation, issuer-signed agent identity tag) and must decide which identity to present per counterparty. Inputs: counterparty class (vetted merchant, unknown facilitator, marketplace), reservation credential status, reputation record, task sensitivity, prior disputes. Rules: present readable reserved ID only to counterparties passing an anchor check on the reservation credential; fall back to an anonymous wallet for unknown sellers; rotate identity after N disputes or any leaked-credential signal; revoke a reservation when a seller fails the handshake twice. Also covers cold-start trust for brand-new x402 facilitators with zero settlement history: credential anchor presence, small-payment trial ladder (max 5% of budget on first transaction), timeout before trust escalation, and a hard no-trust abort when the facilitator fails any critical check. Outputs a single verdict: PRESENT_RESERVED, USE_ANONYMOUS, ROTATE, REVOKE, or ABORT, with evidence fields.

Deterministic dispute resolution for contested x402 settlements. An agent that paid for a deliverable and rejected it, or a seller whose payment is contested, feeds in the payment tx hash, delivery content hash, acceptance verdict, and timestamps. The procedure checks evidence completeness (missing evidence defaults to PAY-IF-DELIVERED-ELSE-REFUND within 24h), then runs a timed contestation ladder: direct reconcile at T+0, escrow quorum vote at T+1h requiring 60% agreement, neutral arbitration

Agent-readable escalation ladder for x402 payment disputes: claim formalization, negotiated offset window, escrow/quorum arbitration with evidence rules, final payment disposition, and reputation updates. Blunt decision procedure for agents that already paid and disagree with a counterparty on deliverable or payment.
