| POST | / | Inspect consolidated domain health · DNS, HTTP, HTTPS, TLS, redirects, MX, SPF, DMARC, email posture, security posture, and agent readiness · returning structured issues, evidence, actions, and stateless changes. USE WHEN: agent needs a comprehensive single-call domain inspection across DNS, web, email, security, and agent-readiness signals. DO NOT USE WHEN: agent only needs DNS records; narrower domain/DNS products are not exposed through MCP. Parameter semantics: `domain` is required; | $0.008 | Base | USDC | header | since 10-27 |
| GET | / | Validate email syntax, domain, and MX records for basic automated checks without SMTP mailbox verification; cannot prove a mailbox exists or can receive mail. USE WHEN: agent needs inexpensive structural and mail-domain validation before using an email address. DO NOT USE WHEN: agent requires proof that a mailbox exists or can receive mail. | $0.005 | Base | USDC | header | since 09-28 |
| POST | / | Return confirmed customer domains currently known for a specified technology/vendor; STRAELO-confirmed coverage, not a complete global installed base.

| GET | / | Extract clean, boilerplate-free readable text from one known public HTTP(S) URL for LLM research or RAG ingestion; private, local, authenticated, paywalled, or blocked resources are not supported. USE WHEN: agent already knows the URL and needs clean page text. DO NOT USE WHEN: agent needs web search, multi-page research, comparison, structured web workflow, or change detection.

How the score works
What the score read on this service: status offline, 96.5% uptime 30d, 279ms response p95, x402 compliance 14 of 14, $0.003 price against the category, on-chain traction measured. 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 497 listings, this one among them: the same 497 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.
Settled via coinbase ($1.20, 58 tx). Traction is a conservative undercount; first settlement seen 2026-09-27.

What it does
Straelo Relay provides machine-consumable web research, search, structured evidence, content extraction, domain intelligence, email validation, and read-only blockchain data services for AI agents. All paid endpoints use x402 payments on Base with USDC.
Straelo Relay is a listed x402 Data API. Captured payment terms name Base. 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 . Latest service check observed at . Service data JSON · Measurement methodology.
Page rendered at . This response time is separate from the observation and computation times attached to each measurement.
Latest endpoint observation: . Latest price capture: . 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 . 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: 2026-10-15 to 2026-11-13 UTC. Daily monitoring and settlement rollups do not expose their computation time; a bucket date is not an update timestamp. Latest settlement in the assessment: . Uptime and response JSON · Volume JSON · Buyers JSON · Measurement methodology.
Ranked from the measured category pool, refreshed at most once a minute. The comparison has no persisted computation timestamp; the assessment time above belongs to this service only. Ranking API documentation · Ranking methodology.

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Assessment volume uses the latest 30d assessment. Over time sums daily address snapshots, rounded to cents and refreshed separately. The two sources can differ in timing, precision and shared-address attribution. Amounts use cents for comparison; known sub-cent values keep up to 12 significant digits. The exact stored assessment value is shown above.
Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.
Top buyer share lowers the on-chain traction part of the ranking score behind this page's verdict and /best, by up to half when one address holds all 30d volume. The Recommended and Highest volume sorts of the services list do not use it; they use the Concentrated volume rule instead.

Scores: one day per column, 10-15 to 11-13, on the columns of Response time. Uptime held below 100% on some days in this window, including any partial day. Daily readings remain in the Uptime strip and Values. The checklist grew from 11 to 14 checks on 2026-07-28, before this window. Pillar lines use their own low and high. Exact dated readings are available in each readout and in Values.
Each series spans only the dates it has data for. Every series is also served as JSON at /api, /scores, /volume and /buyers.
Values
The uptime summary counts completed UTC days only. The strip, readouts and table retain today's partial reading.
Daily snapshot total, 30d: $0.85, peak $0.24 on 10-18. The visible 30d total in Traction comes from the latest assessment. These sources can differ in their window, refresh time, cent rounding and shared-address attribution.
Daily address snapshots: 2026-10-15 to 2026-11-13 UTC. Daily snapshots store cents. A recorded $0.00 with settlements cannot distinguish exact zero from volume rounded away. Lost precision is unavailable here. † marks a recorded $0.00 with settlements.
Settlement volume uses the stored USD valuation of tracked payments; it is distinct from token quantities. USD-pegged assets are valued at 1 USD per token in these rollups. The measured settlement floor does not cover all payments to this service.
Assessment history last recorded at . Each UTC day uses its last recorded run; missing readings stay unmeasured. Assessment history JSON · Measurement methodology.
