What is APIbase?

Production MCP server that gives AI agents access to 300 real-world API tools through a single endpoint. Agents connect once to https://apibase.pro/mcp and can search flights, get stock quotes, translate text, check weather alerts, generate images, send emails, look up holidays, shorten URLs, detect fires by satellite, decode VINs, look up food products — and 200+ more tools across 30+ categories.

Built for AI agents, not humans. Auto-registration, zero setup, pay-per-call via x402 USDC micropayments on Base.

How Payment Works

No subscriptions. No minimums. Agent pays only for successful calls. Failed provider calls are auto-refunded.

13-Stage Pipeline

Every tool call passes through:

AUTH → IDEMPOTENCY → CONTENT_NEG → SCHEMA_VALIDATION → TOOL_STATUS →
CACHE → RATE_LIMIT → ESCROW → PROVIDER_CALL →
ESCROW_FINALIZE → LEDGER_WRITE → CACHE_SET → RESPONSE

• Escrow-first: USDC locked before provider call, refunded on failure
• Idempotent: same request + same key = same result, no double charges
• Cache: per-tool TTL (5s for stock prices, 7 days for walkability scores)
• Fail-closed: Redis down = reject all, no silent degradation

Authentication

Auto-registration: agents get API keys instantly on first request. No forms, no approval.

Error Codes

MCP Discovery

GET /.well-known/mcp.json → MCP server metadata
GET /api/v1/tools → Full tool catalog with schemas (all 300 in one response)
GET /health/ready → System health check

Integrations

Architecture

• 16 Docker containers: API, Worker, Outbox, PostgreSQL, Redis, Nginx, Prometheus, Grafana, Loki, Promtail, Alertmanager, exporters
• Single Hetzner server with automated health checks, graceful shutdown, and 27 Prometheus alert rules
• PostgreSQL = source of truth for financial data (append-only ledger)
• Redis = cache, rate limiting, single-flight deduplication
• Fail-closed: any infrastructure failure = reject requests, never pass through

Self-Hosting

git clone https://github.com/whiteknightonhorse/APIbase.git
cp .env.example .env    # configure secrets
docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d
