Agent Tools (pay-per-call utilities for AI agents)

payment-readyonline

payment-ready until 2026-11-11

Three pay-per-call utilities for AI agents, USDC on Base or Solana: /web/read turns any public web page into clean LLM-ready Markdown ($0.001, honors robots.txt, not charged on fetch errors); /compliance/sanctions screens up to 50 crypto addresses against the OFAC SDN digital-currency list ($0.002 per batch); /x402/preflight checks an x402 endpoint's 402 offer before an agent pays it (network, canonical stablecoin, price vs max, payTo contract/OFAC screen, host mismatch) and returns ok/caution/review/do_not_pay ($0.002).

Method	Path	Description	Price	Network	Asset	402 channel	Captured
GET	/compliance/sanctions	Screen up to 50 crypto addresses (EVM, Bitcoin, Tron, Solana, Litecoin, Monero, Zcash and more) against the digital currency addresses on the US Treasury OFAC SDN list. Returns sanctioned true/false per address, the SDN asset tags, list size and list update date (refreshed every 6 h). Use before an agent pays or accepts funds. Params: address or addresses (comma separated, max 50). $0.002 per call (whole batch) in USDC on Base or Solana. Exact-match screen only; not legal advice.	$0.002	Base+Sol	USDC	header	since 11-04
GET	/web/read	Fetch a public web page and return clean Markdown for LLMs: title, description, canonical URL, language, word count, body as Markdown (headings, lists, links, tables, code) and the list of absolute links. Uses the page main/article element when present; scripts, styles and (by default) nav/footer/sidebars are stripped. No headless browser, so JavaScript-only pages return little text (flagged with a hint). Honors robots.txt. Params: url (required), max_chars (500-100000, default 20000), links (true/false), include_nav, images, full_page (true/false). $0.001 per URL in USDC on Base or Solana. Not charged if the page fails, is blocked by robots.txt or is not HTML/text.	$0.001	Base+Sol	USDC	header	since 11-04
GET	/x402/preflight	Check an x402 endpoint BEFORE your agent pays it. Calls the URL unpaid, decodes the 402 offer (v2 PAYMENT-REQUIRED header or v1 body) and returns every payment option normalized: network, token, canonical-stablecoin check, human price in USD, payTo, payTo contract-or-wallet, OFAC SDN screen of payTo, resource-host mismatch, testnet-only, missing discovery metadata, and price above your max_usd. Verdict ok / caution / review / do_not_pay. Params: url (required), method (GET\|POST), max_usd (optional). $0.002 per check in USDC on Base or Solana.	$0.002	Base+Sol	USDC	header	since 11-04

How the score works

What the score read on this service: status online, 100% uptime, latest daily rollup (no 30d window yet), 142ms response p95, x402 compliance 14 of 14, $0.001 price against the category. Each of those is measured, and each is published in full below.

The score comes from our own monitoring, never from reviews, operator claims, or a language model: reliability, x402 compliance, price against the category, a deterministic risk flag, and a small on-chain traction term, weighted by ranking generation 3. It is not placement anyone can buy: the paid verify tier is reported beside it and is not one of its inputs. Every component below stays published and read-only.

Bands on the 0 to 100 measured score: strong at 93 and above, solid from 75, mixed from 55, weak below 55. Price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, so the score places a service in its own field.

It is a score inside Data, and only there: price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, which here means 462 listings, this one among them: the same 462 the position above is counted against. When the two differ, the field is the wider one, because a listing we have measured too little of to rank still sits in the field the price and the speed are normalized over. The same service in a different field would read differently. The same engine answers GET /api/v1/best, and asked for a different pool (the whole directory, or another filter) it returns a different number for this service under this same ranking generation. Neither is more correct: they answer different questions, and the methodology states which is which.

All measured facts

What it does

Agent Tools (pay-per-call utilities for AI agents) is a listed x402 Data API. Captured payment terms name Base, Solana. Monitoring and settlement figures below describe the observations available to this directory; an unpaid HTTP 402 check does not prove that a paid call will deliver.

Assessment computed at 2026-11-04 17:33:11 UTC. Latest service check observed at 2026-11-04 19:41:01 UTC. Service data JSON · Measurement methodology.

Page rendered at 2026-11-04 19:44:13 UTC. This response time is separate from the observation and computation times attached to each measurement.

Latest endpoint observation: 2026-11-04 19:41:01 UTC. Latest price capture: 2026-11-04 17:32:57 UTC. Prices are recorded quotes, not a promise of availability. Token assets and payment terms are listed separately. Endpoint data JSON · Price history JSON · Measurement methodology.

Assessment computed at 2026-11-04 17:33:11 UTC. Uptime uses the stated daily-rollup window; response times are in milliseconds, compliance is passed/evaluated checks, and traction is a measured settlement floor. The comparison score is out of 100 within this category. Assessment JSON · Measurement methodology.

Observed daily coverage: 2026-10-06 to 2026-11-04 UTC. Daily monitoring and settlement rollups do not expose their computation time; a bucket date is not an update timestamp. Uptime and response JSON · Volume JSON · Buyers JSON · Measurement methodology.
