Two public API price pages, read on the dates shown, with the figures as published. Prices change, so check the source before you copy a number. This page is a free reference for the API pricing guide and the pricing checklist.
Source: twilio.com/en-us/sms/pricing/us. Pay-as-you-go, per segment, US long code:
| Type | Outbound SMS | Inbound SMS | Outbound MMS |
|---|---|---|---|
| Long code | $0.0083 | $0.0083 | $0.022 |
Carrier fees apply on top per message, and messages that fail are charged $0.001. The lesson: a usage-based provider prices per unit, then lists the pass-through fees separately. Show the total cost per unit, not just the base rate.
Source: openweathermap.org/price. Prices are in GBP as published.
| Option | Price | Limit |
|---|---|---|
| One Call, pay per call | first 1,000 calls/day free, then 0.0012 GBP per call | per day |
| Startup plan | 30 GBP per month | 600 calls/min, 10M calls/month |
| Developer plan | 140 GBP per month | 3,000 calls/min, 100M calls/month |
| Professional plan | 370 GBP per month | 30,000 calls/min, 1B calls/month |
| Expert plan | 1,200 GBP per month | 100,000 calls/min, 3B calls/month |
The pattern to notice: a free daily allowance, then a low per-call price, plus monthly tiers that are priced by limits (calls per minute and per month), not by features. Each tier's cap is what you're really selling.
A third data point: Stripe's published card fee (2.9% + 30 cents) on $1 to $100 plans is in the Stripe fee table.
