How this service works

Subscribe a webhook to Agent Paywire alerts for 30 days. POST JSON with webhook_url and one to four topics: sdk-security, lightning-releases, lightning-wallets, protocol-specs. One subscription is 2.00 USDC. The token and HMAC secret are returned once.

Output

Returns a subscription object containing a unique subscription ID (UUID), the list of topics subscribed, and an expiration timestamp indicating when the subscription will lapse.

Example use cases

SDK security advisory monitoring

“Set up an Agent Paywire alert to my webhook at https://alerts.myagent.io/paywire for sdk-security updates so I'm notified immediately if there's a vulnerability in any agent payment SDK.”

Protocol spec change tracking

“Register my endpoint https://infra.mycompany.com/webhooks/paywire with Agent Paywire to watch protocol-specs and lightning-releases — I want a ping every time there's a new x402 or Lightning protocol update.”

Lightning wallet release notifications

“Hook up my server at https://ops.mybot.dev/hooks/agentpay to Agent Paywire and subscribe it to lightning-wallets so my agent knows whenever a new Lightning wallet compatible with machine-to-machine payments drops.”

When to prefer

Use this endpoint when you need proactive, push-based notifications about AI agent payment infrastructure changes rather than polling. It is ideal for agents or CI/CD systems that need to react immediately to security advisories, protocol spec changes, or Lightning wallet/release updates without continuously querying a news or changelog feed. Prefer it over manual polling or RSS feeds when you need structured, signed, machine-readable webhook payloads and want to filter by specific topic categories.

Side effects

Invalid or unreachable webhook_url — endpoint returns an error if the URL is not a valid public HTTP/HTTPS address
Empty or out-of-range topics array — must contain 1 to 4 valid topic enum values; invalid topic strings cause validation failure
Payment failure — as a $2 USDC x402-gated endpoint, failure to include valid payment header results in 402 Payment Required
Duplicate subscription — re-registering the same webhook/topic combination may return a conflict or overwrite existing subscription
Expired subscription — the returned expires_at date means the subscription silently stops delivering after that date unless renewed
