INTRODUCTION

What is Xynaptic?

Xynaptic is a pay-per-call platform of 200+ real-world data and intelligence services built for AI agents — and readable by humans. Official sources, fresh data, signed responses.

Your agent sends a request, pays the exact price in USDC through the x402 protocol, and receives structured JSON with proof. No account. No API key. Pay per call — or pick a monthly plan. From $0.01 to $2 per call.

HOW IT WORKS

Designed for autonomous transactions

Services use the x402 payment protocol to let an agent discover a price, authorize a payment and receive the result.

01 / DISCOVER

Find a capabilityYour agent selects an endpoint from the catalog or through MCP.

02 / REQUEST

Call the APIThe agent sends a standard HTTP request to the chosen service.

03 / PAY

Settle with x402The payment challenge specifies the amount and supported network.

04 / RECEIVE

Use the resultAfter payment verification, the endpoint returns its response.

Units = service price ×100 (a $0.02 call = 2 units). Quota exceeded? Calls automatically fall back to pay-per-call x402 — never blocked.

Per-service plan — $4/month for ONE service: POST /v1/sub-buy {"plan":"svc-ai-chat"}. Available 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). ai-brief-me is a store bundle, no unit plan. The relay scopes it: any other endpoint falls back to pay-per-call.

1 — Buy a plan (agent / x402 client)

curl -X POST https://api.xynaptic.io/v1/sub-buy \   -H "Accept: application/json" \   -H "Content-Type: application/json" \   -d '{"plan":"median"}'

2 — Call any service with your key

curl 'https://api.xynaptic.io/v1/company-profile?siren=552100554' \   -H "Authorization: Bearer sub_YOURKEY"

3 — Check your quota (free)

curl -X POST https://api.xynaptic.io/v1/sub-status \   -H "Content-Type: application/json" \   -d '{"sub_key":"sub_YOURKEY"}'

Step 1 returns a 402 challenge of 29 USDC — pay it and the response contains your sub_key.

MCP users: set XYNAPTIC_SUB_KEY in your environment. Details and plan comparison: the pricing page.
