Trust signals, by the request.

Every call is a paid x402 endpoint your buyer agent invokes directly. EIP-191 signed receipts, sub-second cached reads, zero API keys.

POST /api/route

mako_route

Single-call routing. Submit a canonical task; MAKO composes Verifier + Pulse + Pricing + Reputation into one decision plus a signed receipt valid for 60s.

$0.05 USDC · per call

POST /api/agent-commerce/verify

mako_verify

Pre-spend trust check. Validates a target's /.well-known/x402.json, route schemas, settlement readiness. Verdicts: callable / proceed_with_caution / not_callable.

$0.25 USDC · per call

GET /api/pulse/score

mako_pulse

Per-endpoint reliability score (0-100) from the verification ledger. Callable rate, schema compliance, settlement success, latency p50/p95.

$0.02 USDC · per call

GET /api/pricing/index

mako_pricing

Category market-rate distributions — min, p25, median, mean, p75, p95, max — across 9 task categories. For routing agents and budget agents.

$0.02 USDC · per call

GET /api/reputation/wallet

mako_reputation

Per-wallet operator trust. Aggregates callable rate, schema compliance, settlement readiness across every endpoint that wallet operates. ERC-8004 aligned.

$0.03 USDC · per call

GET /api/markets/aggregate

mako_markets_aggregate

Top prediction markets across Polymarket + Kalshi + Limitless in one signed call. Normalized schema, snapshot persisted for v2 calibration.

[ POST /api/route ] [ $0.05 ]

The composition apex.

One buyer-agent call returns the best x402 service to invoke for a canonical task — plus up to 3 ranked alternatives and an EIP-191 signed receipt valid for 60 seconds. Composes Verifier preflight, Pulse reliability, Pricing Index fairness, and Reputation Score operator trust into a single decision.

Prediction markets, normalized.

One call returns the top markets across Polymarket gamma-api, Kalshi elections-api, and Limitless markets/active — normalized to a single schema, ranked by volume, EIP-191 signed. Every response persists a snapshot row that feeds a forthcoming calibration dataset.

MAKO Pulse is wired into AsterPay's facilitator response.

Every /v1/scan/full call through AsterPay's x402 facilitator carries MAKO Pulse data under extensions.reliability. Buyer agents pay a chained $0.02 settlement; AsterPay's facilitator forwards our share on every Pulse-attached call. Same EIP-191 signing recipe, same RFC 8785 canonical bytes, same envelope shape both directions.
