AI agent quickstart

Give an AI coding agent (Claude Code, Cursor, Codex, Windsurf, Copilot, or any chat agent) a single link and it can read the entire integration surface:

https://docs.tribridge.xyz/llms-full.txt

Paste this into your agent together with your task. It is written to prevent the most common integration mistakes.

Copy-paste prompt

Integrate Tribridge crypto payments into this app using the official docs.

Read these first (fetch them, do not guess):
- https://docs.tribridge.xyz/llms-full.txt        (all documentation in one file)
- https://docs.tribridge.xyz/openapi/openapi.json (machine-readable API spec)

Rules:
- API base URL is https://api.tribridge.xyz
- Only use endpoints documented in those files. Do not invent endpoints, query
  parameters, response fields, or SDK packages (official SDKs are not released).
- Create payments server-side with the header "x-api-key: tri_test_...".
  The key prefix decides test vs live mode. Never put API keys in frontend code.
- Redirect the customer to the returned "checkout_url" - do not build your own
  chain, deposit address, or amount logic.
- Poll GET /payments/checkout/{id} for status, and treat webhooks as the source
  of truth. Verify the X-Tribridge-Signature header (HMAC-SHA256 over the raw
  request body) before trusting any webhook payload.
- Test mode is simulated, not a testnet: complete a payment with
  POST /payments/checkout/{id}/simulate. No real funds move.

Implement the smallest working flow first (create payment -> redirect to
checkout -> poll status), then add the webhook handler.

Machine-readable resources

Resource	URL	Purpose
Full docs	`https://docs.tribridge.xyz/llms-full.txt`	Every page in one Markdown file
Docs index	`https://docs.tribridge.xyz/llms.txt`	Titles, descriptions, and links
OpenAPI 3.1	`https://docs.tribridge.xyz/openapi/openapi.json`	Endpoints, parameters, schemas, status codes, examples
MCP server	`https://docs.tribridge.xyz/mcp`	Read-only search and retrieval for MCP-capable agents
Any page as Markdown	`https://docs.tribridge.xyz/<slug>.md`	e.g. `/create-checkout-session.md`

Connect the docs as an MCP server

Agents that support remote HTTP MCP servers can read this documentation directly through tools instead of scraping pages:

Example MCP config

{
  "mcpServers": {
    "tribridge-docs": {
      "url": "https://docs.tribridge.xyz/mcp"
    }
  }
}

The server is read-only, requires no authentication, and only exposes the public documentation. It does not call the payments API.

Ground truth

Keep these facts in context; they override anything the agent inferred from another source.

Topic	Value
API base URL	`https://api.tribridge.xyz`
Auth	`x-api-key: tri_test_...` or `tri_live_...` on `POST /payments` only
Mode	Decided by the key prefix, never by the request body
Minimum amount	`0.50`
Rate limit	100 requests per minute per IP (`429` on exceed)
Currency	`currency` is the checkout label; the payer settles 1:1 in `coin_symbol` (`USDC` or `USDT`, default `USDC`)
Chains	Solana and Sui (chosen by the customer at checkout)
SDKs	None published yet - use the REST API
Test mode	Fully simulated: `POST /payments/checkout/{id}/simulate`
Refunds	Automatic for underpayment and overpayment; no manual refund endpoint
Webhook auth	HMAC-SHA256 signature in `X-Tribridge-Signature`, plus `X-Tribridge-Timestamp`

Minimal happy path

Create the payment (server-side)

curl -X POST https://api.tribridge.xyz/payments \
  -H "Content-Type: application/json" \
  -H "x-api-key: tri_test_your_key_here" \
  -d '{"amount":25.00,"currency":"USDC","redirect_url":"https://yoursite.com/success","description":"Order #1234"}'

Abridged response:

{
  "id": "b3f1c2a0-1d4e-4f2a-9c8b-2e7a6f5d4c3b",
  "amount": "25.00",
  "currency": "USDC",
  "status": "pending",
  "is_test": true,
  "expires_at": "2026-08-25T12:30:00.000Z",
  "checkout_url": "https://tribridge.xyz/gateway?payment_id=b3f1c2a0-1d4e-4f2a-9c8b-2e7a6f5d4c3b"
}

Store id against your order. Never expose the API key to the browser.

Send the customer to checkout

Redirect to checkout_url. Tribridge handles chain selection, the one-time deposit address, amount display, and on-chain confirmation.

Track status

curl https://api.tribridge.xyz/payments/checkout/{id}

Key fields: status, chain, wallet_address, tx_hash, expires_at. Terminal states are completed, expired, and cancelled.

Complete a test payment

curl -X POST https://api.tribridge.xyz/payments/checkout/{id}/simulate

Test payments only. This marks the session completed and fires your test webhooks, so you can validate fulfillment without a chain transaction.

Trust webhooks, not the redirect

Verify X-Tribridge-Signature (HMAC-SHA256 over the raw body with your endpoint secret) and make the handler idempotent. Events: payment.confirmed, payment.swept, payment.completed, payment.expired, payment.underpaid, payment.overpaid.

Implementation checklist

Payment creation runs on the server with x-api-key from an environment variable.
The app redirects to checkout_url and never derives its own deposit address.
Status is driven by GET /payments/checkout/{id} and by webhooks, not by the customer’s browser.
Webhook signatures are verified against the raw body before parsing.
Webhook handling is idempotent (dedupe on payment_id + event).
Test mode is exercised end to end with /simulate before switching to tri_live_....
API keys and webhook secrets are never committed or shipped to the client.

What not to do

Do not use dashboard, admin, auth/OTP, payout, wallet, or webhook-management endpoints - they are dashboard-only and not part of the public API.
Do not treat the redirect to redirect_url as proof of payment. Only payment.completed (after signature verification) means funds are settled.
Do not assume a fixed amount in native units - read the amount from the checkout session or webhook payload.
Do not assume exactly-once webhook delivery; retries can repeat an event.
Do not guess response fields. Everything is documented in the API Reference and the OpenAPI file.
