# AsyncBase > Redis-grade queues with Supabase-grade DX. Idempotent enqueue, exponential > backoff retry, DLQ + redrive, FIFO ordering + dedup, delayed delivery, > per-tenant API keys. HTTP/JSON API with Bearer auth. This file is the LLM discovery index for AsyncBase. Each link points to a markdown doc optimized for LLM code generation: schema-first, short, example-heavy, no marketing. ## Concepts - [Overview](https://api.asyncbase.dev/docs/llm/overview.md): What AsyncBase does, mental model, vs alternatives. - [Authentication](https://api.asyncbase.dev/docs/llm/auth.md): API key format, header, rotation, revocation. - [Errors](https://api.asyncbase.dev/docs/llm/errors.md): Every error code + envelope shape. - [Rate limits](https://api.asyncbase.dev/docs/llm/rate-limits.md): Per-plan limits, 429 semantics, headers. ## Operations - [Enqueue](https://api.asyncbase.dev/docs/llm/enqueue.md): send, idempotency, delay, FIFO, dedup. - [Consume](https://api.asyncbase.dev/docs/llm/consume.md): pull, ack, nack, heartbeat, long-poll. - [Retries + DLQ](https://api.asyncbase.dev/docs/llm/retries.md): Exponential backoff math, DLQ, redrive. - [FIFO + dedup](https://api.asyncbase.dev/docs/llm/fifo.md): fifo_group ordering, dedupe_id window. - [Delayed delivery](https://api.asyncbase.dev/docs/llm/delay.md): delay + scheduled ZSET sweep. - [Tail (SSE)](https://api.asyncbase.dev/docs/llm/tail.md): Live observer stream. ## SDKs - [Node / TypeScript](https://api.asyncbase.dev/docs/llm/sdk/node.md): `@asyncbase/sdk` - [Python](https://api.asyncbase.dev/docs/llm/sdk/python.md): `asyncbase` - [PHP](https://api.asyncbase.dev/docs/llm/sdk/php.md): `asyncbase/asyncbase` - [Go](https://api.asyncbase.dev/docs/llm/sdk/go.md): `github.com/asyncbase/asyncbase-go` ## AI tooling - [MCP server install + config](https://api.asyncbase.dev/docs/llm/mcp.md): `npx @asyncbase/mcp` — 7 tools including `get_docs`. - [Claude Code skill install](https://api.asyncbase.dev/docs/llm/claude-skill.md): `asyncbase` skill that scaffolds the SDK into any project. ## Framework wiring - [NestJS](https://api.asyncbase.dev/docs/llm/framework/nestjs.md): OnApplicationBootstrap consumer pattern. - [FastAPI](https://api.asyncbase.dev/docs/llm/framework/fastapi.md): lifespan-managed consumer. - [Laravel](https://api.asyncbase.dev/docs/llm/framework/laravel.md): Artisan command + service provider. - [Next.js / Node](https://api.asyncbase.dev/docs/llm/framework/node.md): Separate consumer process. - [Go / net/http](https://api.asyncbase.dev/docs/llm/framework/go.md): goroutine + context cancel. ## Spec - [OpenAPI 3.1 (YAML)](https://api.asyncbase.dev/openapi.yaml) - [OpenAPI 3.1 (JSON)](https://api.asyncbase.dev/openapi.json) ## Full dump (single file) - [llms-full.md](https://api.asyncbase.dev/llms-full.md): All LLM docs concatenated in topological order. Use when you want full context without multiple fetches.
