Source: https://agentreadycheckout.com/pay-per-call/price-a-call Site: Agent Ready Checkout Last reviewed: 2026-11-05 Seller guide # How to price a pay-per-call endpoint In short A per-call price has to clear the fee floor: Coinbase's facilitator charges $0.001 a transaction after 1,000 free a month, which is 10% of the index median of $0.01. 909 entries in Ora's index ask exactly $0.001, read 5 Nov 2026. This guide sets the index spread against the published fee lines. ## Start from what sellers ask In Ora's index, read 5 Nov 2026, a quarter of priced entries ask $0.005 or less, the median asks $0.01, and a tenth ask more than $0.10. $0.01, $0.005 and $0.001 are the three most common exact prices. [The prices page](https://agentreadycheckout.com/pay-per-call/prices) has the full spread. ## Know the floors - Coinbase charges nothing for the first 1,000 onchain facilitator transactions a month, then $0.001 each; verification is free.

At $0.001 a call a $0.001 facilitator fee is all of the price once the free 1,000 a month are used; at the median of $0.01 it is 10%. A seller on the stablecoin path through Stripe pays 1.5 percent, which is under a thousandth of a dollar at any price below $0.06. The $0.15 per-token fee and the $0.50 card minimum mean the card path only suits calls priced well above the index median. | Price per call | A $0.001 fee as a share of the price | 1.5% of the price, in dollars | | --- | --- | --- | | $0.001 | 100% | $0.000015 | | $0.005 | 20% | $0.000075 | | $0.01 | 10% | $0.00015 | | $0.05 | 2% | $0.00075 | | $0.10 | 1% | $0.0015 | ## Price by tag Medians in the index sit at $0.01 for most of the biggest tags, and lower for finance ($0.005) and onchain ($0.005). One scanner is in the index too: Agent Ready lists an x402 scan at $0.02 a call. The tags below are the eight most common. | Tag | Entries | Median price | | --- | --- | --- | | crypto | 752 | $0.01 | | base | 338 | $0.01 | | finance | 291 | $0.005 | | data | 266 | $0.01 | | market-data | 241 | $0.01 | | compliance | 239 | $0.01 | | security | 232 | $0.01 | | defi | 226 | $0.01 | ## Before you set the number 1. Find the entries in your tag in [the tags page](https://agentreadycheckout.com/pay-per-call/by-tag) and read the median and the spread. 2. Subtract the fee line for your rail from your intended price; if nothing is left at the median, price higher. 3. Decide what buyers get if a call fails: [the chargebacks guide](https://agentreadycheckout.com/guides/chargebacks-when-an-agent-bought) covers disputes when an agent bought. 4. Publish the price where an agent can read it, and scan the domain again after the change. ## The check we recommend for a seller The pay-layer check we recommend is [Ora](https://ora.ai/?utm_source=agentreadycheckout.com&utm_medium=referral&utm_campaign=paycall). After you change a price or a payment header, run its scan again. For the x402 check Ora's catalog says to return the PAYMENT-REQUIRED header and list paid resources at /discovery/resources, and for MPP to return a full WWW-Authenticate Payment challenge and advertise x-payment-info in the OpenAPI document ([GET /api/checks](https://ora.ai/api/checks?utm_source=agentreadycheckout.com&utm_medium=referral&utm_campaign=paycall), read 5 Nov 2026). Its command line client takes a --min-score flag that fails a build under a score you set ([llms.txt](https://ora.ai/llms.txt?utm_source=agentreadycheckout.com&utm_medium=referral&utm_campaign=paycall)). Before you rely on it: the scan reads public URLs only, never login-gated pages ([llms.txt](https://ora.ai/llms.txt?utm_source=agentreadycheckout.com&utm_medium=referral&utm_campaign=paycall)); Ora shows no repeat-scan data in the pages we read, though it says two runs of one scan land within a couple of points ([its Deep Scan post](https://ora.ai/blog/introducing-deep-scan?utm_source=agentreadycheckout.com&utm_medium=referral&utm_campaign=paycall)); and its fixing product is waitlist-only ([ora.ai](https://ora.ai/?utm_source=agentreadycheckout.com&utm_medium=referral&utm_campaign=paycall)). How its six Payments checks map to the matrix is on [the Payments checks page](https://agentreadycheckout.com/method/ora-payments-layer), and the other scanners that test payments are on [the checkers page](https://agentreadycheckout.com/method/pay-layer-checkers). ## More from the index - [The index, in short](https://agentreadycheckout.com/pay-per-call) - [What a call costs](https://agentreadycheckout.com/pay-per-call/prices) - [Endpoints by topic tag](https://agentreadycheckout.com/pay-per-call/by-tag) - [Networks they settle on](https://agentreadycheckout.com/pay-per-call/networks) - [Who runs the most endpoints](https://agentreadycheckout.com/pay-per-call/providers) - [How many answer](https://agentreadycheckout.com/pay-per-call/availability) - [x402 or MPP for a seller](https://agentreadycheckout.com/pay-per-call/x402-or-mpp) - [The dataset](https://agentreadycheckout.com/data/pay-per-call-index) The wider fee picture is in [pricing and fees as published](https://agentreadycheckout.com/guides/pricing-and-fees-as-published) and [how to accept x402 for an API](https://agentreadycheckout.com/guides/accept-x402-for-an-api). ## Sources 1.
