How this service works
The (most) everything API: 575+ pay-per-call endpoints for AI agents — ground-truth data, a full AI gateway, and agent infrastructure (storage, queues, watchers). USDC via x402, no signup, no API keys, and upto billing: pay actual usage, not the quote.
Output
Returns a JSON object with ok: true, an items array containing the created topic's topicId and name, a total count, and a source object with provider, URL, and license metadata.
Example use cases
Price alert event bus setup
“Set up a pub/sub topic named 'price-alerts' so my trading agents can broadcast price threshold events to each other in real time.”
Order processing pipeline channel
“Create a new pub/sub topic called 'order-events' on 2s so I can wire up my fulfillment agents to listen for new orders as they come in.”
Agent health monitoring bus
“I need a pub/sub topic named 'agent-heartbeats' to let my fleet of AI agents publish status pings that a monitoring agent can subscribe to.”
Technical details
Endpoint
POSThttps://2s.io/api/pubsub/create-topicWhen to prefer
Use this endpoint when you need to provision a named pub/sub topic as part of building an event-driven agent pipeline on the 2s platform. It is the first step before publishing messages or subscribing to a channel. Prefer this over general-purpose message brokers when you are already using 2s for other agent infrastructure (storage, queues, watchers) and want pay-per-call pricing with no signup.
Side effects
- Invalid topic name (must be 1-64 chars of [A-Za-z0-9._:-]) returns an error response
- Duplicate topic name may return an error or an existing topic depending on platform behavior
- Payment failure via x402 if USDC balance is insufficient
- Network timeout or 5xx if the 2s platform is temporarily unavailable
