In part 1 we looked at what agents pay per call for PDF, speech to text, Solana reads and company data. This is part 2, with six more categories from the same kind of source: the price printed in each x402 Bazaar listing, in USDC, next to the URL and a description. Anyone can read those prices before spending anything.
The snapshot date for every figure below is 2026-10-10. Each category was matched by keyword, then reviewed by name (the screenshot and sanctions categories also by description), and the counts are distinct offers after review. We run Tanod, so we are one of the sellers being compared. Tanod's own routes are not counted among the offers.
Domain availability
16 distinct priced offers on 14 hosts.
| Measure | Value |
|---|---|
| Lowest listed price per call | USD 0.001 |
| Median | USD 0.0095 |
| Highest listed price per call | USD 0.100 |
| Tanod, one name | USD 0.002: 1 offer lists less, 2 list exactly this, 13 list more |
Tanod charges USD 0.0005 per name with a minimum of USD 0.002 per call, so ten names cost USD 0.005 and fifty names cost USD 0.025. The one 50-name listing we found lists USD 0.100. A per-call price is not a per-name price: some listings cap a call at 10 or 20 names, some take one.
Caveats from the page: one listing is USD 0.001 per call, below Tanod's USD 0.002 minimum for a single name. One listing says it returns a registration price, which Tanod does not. Tanod's answer says a name looks free, not that you can buy it, because premium and reserved names can look the same.

WHOIS and RDAP lookups
51 distinct priced offers on 47 hosts.
| Measure | Value |
|---|---|
| Lowest listed price per call | USD 0.001 |
| Median | USD 0.005 |
| Highest listed price per call | USD 0.400 |
| Tanod, one RDAP call | USD 0.002: 3 offers list less, 5 list exactly this, 43 list more |
Tanod charges USD 0.002 per RDAP call, and the same route also covers IP addresses and AS numbers.
Caveats: three listings are USD 0.001 per call. Tanod returns RDAP data only, not raw WHOIS text, and takes one query per call, while a few listings take up to 10 domains.

Public holidays and business days
109 distinct priced offers on 58 hosts.
| Measure | Value |
|---|---|
| Lowest listed price per call | USD 0.0005 |
| Median | USD 0.007 |
| Highest listed price per call | USD 0.050 |
| Tanod, one call | USD 0.001: 1 offer lists less, 13 list exactly this, 95 list more |
Tanod charges USD 0.001 per call for public holidays and USD 0.001 per call for business-day counting. One host lists 21 of the 109 URLs, one per country, so the histogram leans toward its USD 0.01 price.
Caveats: the holiday data is computed from the python-holidays rules, not an official calendar, so lunar, religious and one-off holidays can be estimates or missing for some years. Confirm with an official source for legal or payroll use. One listing is USD 0.0005, and one says it takes up to 25 date calculations in one call, where Tanod takes one.

IBAN, BIC and EU VAT validation
Two groups: 124 distinct priced IBAN or BIC offers on 32 hosts, and 57 distinct priced EU VAT offers on 26 hosts.
| Measure | IBAN and BIC | EU VAT |
|---|---|---|
| Lowest listed price per call | USD 0.001 | USD 0.001 |
| Median | USD 0.005 | USD 0.005 |
| Highest listed price per call | USD 0.211 | USD 0.025 |
| Tanod, one call | USD 0.001: 0 list less, 18 exactly this, 106 more | USD 0.001: 0 list less, 7 exactly this, 50 more |
Across both groups there are 181 offers on 46 hosts, median USD 0.005. One host lists 98 of the 181 URLs, one per country. Without it, the IBAN and BIC median is USD 0.003 (46 offers) and the VAT median is USD 0.005 (37 offers).
Caveats: Tanod's check is offline and covers format and check digits only. Its VAT kind makes no VIES call, so it does not confirm that a number is registered. Of the VAT listings, 19 name a VIES check, and those are the ones to use if registration status matters. Some IBAN listings return bank data or validate up to 2000 IBANs in one call; Tanod takes one identifier per call.

Website screenshots
34 distinct priced offers on 33 hosts.
| Measure | Value |
|---|---|
| Lowest listed price per call | USD 0.001 |
| Median | USD 0.01 |
| Highest listed price per call | USD 0.054 |
| Tanod, one screenshot | USD 0.005: 7 offers list less, 6 list exactly this, 21 list more |
Tanod is not the lowest price here: seven listings are below USD 0.005, from USD 0.001, though we have not tested them. Tanod returns PNG or JPEG as base64, takes a URL rather than your own HTML, and refuses private and internal targets. A refused target, an image over 8 MB or a page that cannot load is not charged. There is no free tier on this route.

OFAC and sanctions address screening
41 distinct priced offers on 36 hosts, all of them screening a crypto address.
| Measure | Value |
|---|---|
| Lowest listed price per call | USD 0.001 |
| Median | USD 0.005 |
| Highest listed price per call | USD 0.1 |
| Tanod, one address | USD 0.002: 3 offers list less, 7 list exactly this, 31 list more |
| Tanod, batch | USD 0.0005 per address, at least USD 0.002 per call, up to 1,000 addresses (USD 0.5) |
Tanod is not the lowest price for a single address: three listings are USD 0.001. Tanod checks the OFAC SDN list only, while some listings say they also check UN, EU, UK or Japan lists. Tanod does not screen by name. For small batches, listings that take 20 or 50 addresses for USD 0.005 are lower than Tanod's USD 0.01 for 20 and USD 0.025 for 50, if they perform as described. One Tanod call takes up to 1,000 addresses, against 20, 25 and 50 in the batch listings we found.

One related note on demand, from the same index. In the CDP Bazaar on 2026-10-10 (Tanod and onesource.io excluded), 31.5% of GET endpoints (3,575 of 11,344) had three or more unique payers in 30 days, against 14.5% of POST endpoints (3,717 of 25,691). That is a correlation, not a cause: GET endpoints are often simple reads, and automated sweepers may prefer them. Details: x402 Bazaar agent demand data
Method and limits
The source is Tanod's index of the x402 Bazaar, queried on 2026-10-10. Each category was matched by keyword, reviewed by name (and by description for screenshots and sanctions), then deduplicated by URL. We excluded adjacent products, for example per-TLD registry pages from WHOIS, VAT rate calculators from VAT validation, and screening by person or company name from sanctions. A looser rule would find more, and a different reviewer might draw the lines differently.
A listed price is the first payment requirement, not a measure of accuracy, freshness, speed or uptime, and some endpoints charge differently by input. Listings can be stale. A few large hosts shape several medians, as the holiday and IBAN/VAT pages show. We have not called the endpoints we list as examples.
