EchoRelay

Hooksbase is event infrastructure for AI agents. It ingests events over four channels — HTTP webhooks, email, hosted forms, and scheduled cron — verifies and persists each one, then routes, transforms, and delivers to five typed outbound destinations: HTTP, AWS SQS, AWS EventBridge, GCP Pub/Sub, and S3-compatible storage. Delivery includes retries with exponential backoff, strict FIFO ordering, a dead-letter queue, and deterministic replay from persisted dispatch snapshots, so an agent can recover events it missed. Five verified provider packs (Stripe, GitHub, Clerk, Slack, Resend) validate signatures on ingest; outbound signing is Standard Webhooks-compatible with rotation overlap. Free starts at 5,000 deliveries/month with no card; Starter $25, Pro $79, and Business $249 add transforms, FIFO, and higher volume.

The collaboration platform for API development. Simplify each step of building an API and streamline collaboration so you can create better APIs—faster. Postman is a collaboration platform for API development. Postman's features simplify each step of building an API and streamline collaboration so you can create better APIs—faster. Quickly and easily send REST, SOAP, and GraphQL requests directly within Postman. Automate manual tests and integrate them into your CI/CD pipeline to ensure that any code changes won't break the API in production. Communicate the expected behavior of an API by simulating endpoints and their responses without having to set up a backend server. Generate and publish beautiful, machine-readable documentation to make your API easier to consume. Stay up-to-date on the health of your API by checking performance and response times at scheduled intervals. Provide a shared context for building and consuming APIs, and collaborate in real-time.
