# Xynaptic

> Real-world data for AI agents — pay per request via x402 (USDC). 200+ live services. No API key, no account. Every response is cryptographically signed and verifiable at https://xynaptic.io/trust

Xynaptic provides real-time, verifiable data for AI agents: French company registry, crypto & DeFi, SEC & EU stocks, banking & payments, energy & grid, aviation, rail, health, real estate, insurance, news. Built for agents: HTTP 402 flow, MCP server, signed responses.

## Quick start for AI agents
- Full API catalog (machine-readable, with live prices and examples): https://api.xynaptic.io/
- Trust & verification page (human + machine readable): https://xynaptic.io/trust
- Live trust card (JSON): https://api.xynaptic.io/trust
- MCP server for Claude / Cursor: https://mcp.xynaptic.io/mcp — or `npx xynaptic-mcp`
- Docs & landing: https://xynaptic.io
- Try for free (no payment): https://api.xynaptic.io/v1/ticket-status

## How it works
1. GET any endpoint without payment -> 402 response with price and payment info
2. Complete the x402 payment (standard HTTP 402 protocol)
3. Retry with payment header -> 200 with data + Ed25519 signature

## Payments
- Networks: Base (eip155:8453), Polygon (eip155:137), Solana (solana:mainnet)
- Prepaid tickets: POST /v1/ticket-buy ($0.50-$20) -> 20% discount via X-TICKET header, 90-day validity. Check balance: /v1/ticket-status

### Monthly plans (optional, no account)
- `llm` $9/mo - the 14 `ai-*` endpoints, 2,500 units, 100 units/hour
- `starter` $15/mo, `median` $29/mo, `pro` $49/mo - full catalog (1,000 / 3,000 / 8,000 units)
- `devkit` $15/mo - 6 dev endpoints. `security` $19/mo - 9 audit endpoints
- `svc-<service>` $4/mo - ONE service only, on the 16 AI Skills endpoints (ai-chat, ai-search,
  ai-agent, ai-company, ai-finance, ai-energy, ai-health, ai-property, ai-insurance,
  ai-industry, ai-bank, ai-translate, ai-validate, skill-crypto-token-audit,
  skill-payment-fraud-screening, skill-supplier-due-diligence)
- Units: units = price_usd x 100 (a $0.02 call = 2 units). A $4 per-service plan carries
  570 units, about $5.70 of calls (30% off). Overage always falls back to pay-per-call.
- Flow: POST /v1/sub-buy {"plan":"svc-ai-chat"} -> 402 challenge (4 USDC / 30 days) -> pay
  with an x402 client (EIP-3009) -> the response carries sub_key -> send it as
  Authorization: Bearer sub_... Scope is enforced per plan; other endpoints return
  403 endpoint_not_in_plan and fall back to pay-per-call.
