The 10 agent-friendly endpoints accept x402 pay-per-call payment in USDC on Base — no account, no API key, no plan. A wallet is the only credential.
How credits work
One formula, every endpoint
Every call costs credits based on the size of the response it returns — a small lookup costs less than a full historical series. The same formula sets both your monthly plan usage and the price of an x402 pay-per-call request.
credits = floor(1 + 0.0004 × responseBytes) price = credits × $0.002
A 1-credit floor means even the smallest response costs something, and larger payloads scale up from there in 0.0004-credit-per-byte increments.

Pricing FAQ
Billing questions, answered
How are CoinCap API credits calculated?
Every call costs floor(1 + 0.0004 × response bytes) credits, with a 1-credit floor. A small lookup like a single asset costs 1 credit; a large historical series can cost 5 or more. The same formula sets both your monthly plan usage and the price of an x402 pay-per-call request.
Is it cheaper to pay monthly or annually?
Annually. Every paid plan bills less per month when paid annually up front — for example Builder is $24/mo billed annually ($288/yr) versus $30/mo billed monthly. The price shown on each plan card is the annual-equivalent monthly rate.
Can I use the CoinCap API for free indefinitely?
Yes. The Free plan includes 500 credits per month and 5 requests per minute with no credit card and no expiration — upgrade only when you outgrow it.
What is MOR staking and how much do I need to stake?
Staking MOR tokens on Base unlocks a paid tier's credits and rate limit without a subscription — an alternative to paying, not a discount on top of it. The stake required scales with the tier: 45 MOR for Builder, 120 for Growth, 338 for Professional, 750 for Enterprise.
Do I need a paid plan to use x402 pay-per-call?
No. Ten agent-friendly endpoints accept x402 payment in USDC on Base with no account, no API key, and no plan at all — priced per call from $0.002 to $0.01 based on the same credit formula.
Does every plan, including Free, include an API key?
Yes. Every plan — including Free — includes an API key you can send as a bearer token or an apiKey query parameter on any REST call.
