# Sendclap

> Sendclap (https://sendclap.com) gives creators and open-source maintainers one page for memberships, tips and digital products. Supporters pay by card or crypto, and Sendclap takes a flat 1% fee with no monthly cost.

## What it does

- Memberships: monthly or yearly tiers with members-only posts, similar to Patreon.
- Tips: one-off payments ("claps") with a message, a public supporter wall and a monthly goal, similar to Buy Me a Coffee.
- Digital products: files and software with their own checkout links, download delivery, license keys and a license validation API, similar to Lemon Squeezy.

## Pricing

- 1% of each payment. No monthly fee and no setup fee.
- Card payments also carry Stripe's processing fee (2.9% + 30¢ in the US), charged by Stripe on the creator's own account.
- Crypto payments cost only the 1%.
- From a $10 card payment a creator keeps about $9.31; from a $10 crypto payment, $9.90.

## How payments work

- Cards: each creator connects their own Stripe account (Stripe Connect Standard). Cards, Apple Pay, Google Pay and Link are supported, and Stripe pays the creator out directly.
- Crypto: supporters pay from any wallet with most tokens on major chains; the payment is converted to USDC on Base and sent straight to the creator's wallet by a public smart contract.
- Crypto memberships use a USDC allowance: the member approves once, and each period exactly the membership price is pulled. Members can cancel or revoke the allowance at any time.
- Sendclap is non-custodial: it never holds creator funds. It is not a merchant of record, so creators handle their own taxes.

## Accounts

- Log in with an email magic link; there are no passwords.
- Supporters don't need an account to pay. They can log in with their email to manage memberships, downloads, license keys and receipts.

## Open source

- Maintainers can add their Sendclap page as a `custom:` link in `.github/FUNDING.yml` so it shows on GitHub's Sponsor button.

## API

- Docs: https://sendclap.com/docs
- `POST /api/v1/checkouts` (bearer API key from the dashboard) creates a checkout for a tip, product or membership and returns a URL to send the payer to; `GET /api/v1/checkouts/{id}` reports whether it is `pending` or `paid`.
- `POST /api/v1/licenses/activate`, `/validate` and `/deactivate` manage license keys per device and need no API key.

## For AI agents

- Look up any creator (public, no key): `GET https://sendclap.com/api/v1/creators/{handle}` returns their tiers, products, prices and payment URLs.
- Pay with x402 (no account, no key, the same 1% fee): `GET https://sendclap.com/x402/{handle}/tip?amount=5` or `GET https://sendclap.com/x402/{handle}/products/{id}?email=you@example.com`. The server answers HTTP 402 with a `PAYMENT-REQUIRED` header (x402 v2, exact scheme, USDC on Base); repeat the request with a `PAYMENT-SIGNATURE` header. The `payTo` address is the creator's split address, a public contract that forwards 99% to the creator and 1% to Sendclap. Product purchases return the license key and download URL.
- MCP server: `https://sendclap.com/mcp` (HTTP transport, stateless). Public tools: `get_creator`, `create_checkout`, `get_checkout`. With a creator's API key as a bearer token: `get_stats`, `list_payments`, `get_payment`, `list_members`, `list_licenses`, `list_disputes`.
- REST data for a creator's own account (bearer API key): `/api/v1/me`, `/payments`, `/payments/{id}`, `/members`, `/licenses`, `/disputes`, `/products`, `/memberships`.
- If you are helping a person pay, use `create_checkout` (or `POST /api/v1/checkouts`) and give them the returned URL.
