x402 Production Runway
x402 turns an HTTP 402 payment challenge into signed payment terms and a retried request. On Tangle, a Blueprint is the typed service contract: each paid request becomes one Job declared by it, facilitators verify and settle payment, and operators execute the work.
For pay-per-request service teams, this series covers pricing, quotes, monitoring, deployment, and safe recovery when payment, facilitator, operator, or result state is uncertain.
Start here: x402 Payments Blueprint: Turn HTTP into a Job. Follow the payment lifecycle: map an HTTP payment to a Job; choose a facilitator and price; design quotes, monitoring, distribution, and protected execution; then deploy, recover failures, and assess product fit.
x402 Payments Blueprint: Turn HTTP into a Job
An x402 payment authorizes one Tangle Blueprint job over HTTP; this guide covers settlement, quote expiry, retries, and evidence after execution.
The x402 Facilitator: Trust, Uptime, and Safer Failure
An x402 facilitator verifies and settles payments; compare hosted, self-hosted, and local options for uptime, trust, and safe failure.
Pay-Per-Request API Pricing: Wei and Markup
Pay-per-request API pricing in Tangle explains how wei amounts become accepted-token units, including decimals, markup, and quote freshness.
Subscription vs Pay-Per-Request API Pricing
Compare subscription and pay-per-request API pricing across margins, billing work, customer needs, latency, and a hybrid implementation for teams and agents.
On-Chain Compute Quotes: RFQ and Slashing
Design the quote protocol: bind inputs, operators, and price to a job, restrict result submission, and define evidence and disputes before slashing.
Blueprint Operator Monitoring: Health and Quotes
Choose the runtime, heartbeat, quote, payment, and result signals an operator should expose before a service quietly stops accepting work.
x402 Operator Economics: Pricing Two Payment Paths
x402 operator economics starts by separating HTTP payments from Tangle service fees, then pricing operator costs, stake shares, payouts, and penalties.
Secure Code Execution for AI Agents: TEEs and Payment
Secure AI-agent execution uses payment for admission; trusted environments limit access; attestation identifies workloads; result checks test correctness.
How to Deploy an AI Agent Service With Remote Providers
Deploy an AI agent service with paid HTTP ingress, remote operators, reproducible runtimes, health checks, and rollback for failed jobs.
RFQ Job Quotes on Tangle
Implement signed RFQ fields, expiry, replay protection, result authorization, and recovery when the selected Tangle operator fails.
Operator Health Monitoring: Heartbeats and Recovery
Diagnose stale heartbeats, expired quotes, and worker failures, then decide which checks must pass before reopening paid traffic.
x402 Blueprint Production Deployment Checklist
A rollout checklist for taking an x402-enabled Blueprint from dev to staging to mainnet without silent payment or config failures.
