View OpenAPI Document

Change is a donations platform that lets businesses embed nonprofit giving into checkout, transactions, and customer-facing flows. The API exposes endpoints for creating donations, listing and looking up vetted nonprofits, retrieving past donation records, and calculating carbon offset and crypto donation amounts. It is designed for fintech, e-commerce, and crypto products that want to route a percentage of revenue or rounded-up change to charity without managing 501(c)(3) compliance themselves.

Use Cases

Patterns agents use Change API V1 API for, with concrete tasks.

★ Round-Up Donations at Checkout

E-commerce stores and fintech apps can let customers round up purchases to the nearest dollar and donate the difference to a vetted nonprofit. The Change API handles nonprofit selection, donation creation, and tax-receipt generation, so the merchant only needs to surface a checkbox and pass the rounded-up amount to the donations create endpoint. Integration typically takes under a day for a basic rounding flow.

Create a $0.43 donation to a nonprofit selected from the climate category and confirm the donation record was returned with a receipt URL

Carbon Offset Calculations

Travel, shipping, and crypto applications often need to translate a CO2 footprint into a dollar donation amount that funds reforestation or carbon-removal nonprofits. The carbon_calculate endpoint converts a tonnage input into a USD price and the carbon_stats endpoint surfaces aggregate offset totals for transparency dashboards. This removes the need to maintain offset price tables in-app.

Call carbon_calculate for 2.4 tons of CO2 and submit a donation for the returned amount to a verified climate nonprofit

Crypto Charitable Giving

Crypto wallets and exchanges can offer users an easy way to donate digital assets to nonprofits without handling on-chain conversions themselves. The crypto_calculate endpoint returns the fiat-equivalent USD amount for a token quantity, which can then be passed to the donations create endpoint to generate a tax-deductible record.

Use crypto_calculate to determine the USD value of 0.05 BTC and create a donation for that amount to a selected nonprofit

AI Agent Donation Flows via Jentic

An AI agent can take a natural-language instruction like 'donate 5 dollars to an ocean conservation charity' and resolve it end-to-end through Jentic. The agent searches Jentic for the donation operation, lists nonprofits filtered by category, picks a verified charity, and submits the donation create call. Credentials never reach the agent, and the entire flow takes seconds rather than days of direct integration.

Search Jentic for 'create a charitable donation', filter nonprofits by 'ocean conservation', and submit a $5 donation to the top result

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Change uses HTTP Basic auth with a secret key. Jentic stores the key encrypted in the MAXsystem vault and issues scoped, short-lived execution tokens to the agent so the secret never enters the model context or logs.

Intent-based discovery

Agents search Jentic with intents like 'create a charitable donation' or 'list nonprofits by cause', and Jentic returns the matching Change operation with its full input schema so the agent can call it directly.

Time to first call

Direct Change integration: 1-3 days for auth, nonprofit lookup, and donation creation. Through Jentic: under 30 minutes — search, load, execute.

Related APIs

Alternatives and complements available in the Jentic catalogue.

Complementary

Stripe API

Stripe handles the payment capture; Change directs a portion of the captured funds to a vetted nonprofit.

Use Stripe alongside Change when you need to charge the customer first, then route a percentage of the proceeds as a donation.

Complementary

PayPal Catalog Products

PayPal can capture the underlying transaction while Change records the charitable portion.

Choose PayPal as the payment rail when the merchant already accepts PayPal and wants to layer giving on top.

Complementary

FastSpring API

FastSpring handles SaaS checkout while Change routes optional add-on donations.

Pair with FastSpring when monetising a software product and offering customers an opt-in charitable add-on.

FAQs

Specific to using Change API V1 API through Jentic.

What authentication does the Change API use?

The Change API uses HTTP Basic authentication over TLS, with your public and secret keys passed as the username and password. When you call this API through Jentic, your Change credentials stay encrypted in the Jentic vault and the agent receives a scoped execution token rather than your raw secret key.

Can I create one-time donations to any 501(c)(3) nonprofit with the Change API?

Yes. Call POST /api/v1/donations/create with the nonprofit ID (looked up via /api/v1/nonprofits/list) and an amount in USD cents. The donation is recorded against the vetted nonprofit and Change handles the tax-receipt and disbursement workflow.

How do I calculate a carbon offset donation with the Change API?

Use GET /api/v1/donations/carbon_calculate with a CO2 tonnage parameter. The endpoint returns a USD amount that can be passed directly to /api/v1/donations/create against a climate-focused nonprofit to fund verified offsets.

What are the rate limits for the Change API?

Change does not publish a fixed public rate limit; production limits depend on your account tier. Treat the API as a payment-grade integration: implement exponential backoff on 429 responses and avoid bursting more than a few requests per second from a single key.

How do I create a donation through Jentic?

Install the Jentic SDK with pip install jentic, search for the operation with a query like 'create a charitable donation', load the schema for POST /api/v1/donations/create, and execute with the nonprofit ID and amount. Sign up at https://app.jentic.com/sign-up to get an API key.

Does the Change API support crypto-denominated donations?

Yes. The /api/v1/donations/crypto_calculate endpoint converts a crypto token amount into a fiat-equivalent USD value. You then submit that USD amount to the donations create endpoint, which produces a standard tax-deductible record on behalf of the donor.
