Endpoints and prices
| Method | Path | Description | Price | Network | Asset | 402 channel | Captured |

| POST | / | Legacy alias for the Signal Forge Prospect Qualifier paid endpoint. | $0.01 | Base | USDC | header | since 09-14 |
| POST | / | Inspect 1-10 public campaign links for HTTP status, up to three redirects, expected destination and lost or mismatched UTM tags. Fixed fee including partial results. No charge if no URL can be inspected. No JavaScript, form submission or checkout testing. | $0.03 | Base | USDC | header | since 09-23 |
| POST | / | English PNG/JPEG static-ad OCR preflight: compare approved copy, locate low-confidence text and edge proximity, report image dimensions and annotated word boxes. Automated review aid, not a guarantee of spelling, contrast, product fidelity or ad-platform approval. | $0.05 | Base | USDC | header | since 09-21 |
| POST | / | Inspect supplied email HTML (up to 40,000 characters) for unresolved placeholders, image alt attributes, link syntax and unsubscribe markup. Optional check of up to five safe public links. Does not render inboxes, assess deliverability or certify compliance. | $0.03 | Base | USDC | header | since 09-23 |
| POST | / | Public HTML URL to bounded Markdown, source URL, retrieval time and content hash. No JavaScript, login, PDF or CAPTCHA bypass. Unsupported or oversized content fails before settlement.

| POST | / | Fact-preserving listing formatter for Etsy, eBay and Shopify: titles, bullets, description, keyword suggestions, character checks and claim-risk flags. Rules-based, not keyword-volume research or platform compliance certification. | $0.03 | Base | USDC | header | since 09-21 |
| POST | / | Ad copy and public landing-page URL to evidence-linked checks for missing offer phrases, numbers, CTA and lead-capture elements. Bounded HTML inspection, not rendered-page vision or semantic conversion prediction. | $0.03 | Base | USDC | header | since 09-21 |
| POST | / | Check 2-5 ad/page pairs for literal offer and CTA consistency. Fixed $0.10 per batch including partial success; no charge when all pages are unavailable. Static HTML evidence, not semantic or visual conversion analysis. | $0.10 | Base | USDC | header | since 09-23 |
| POST | / | Fetch a public page and compare sampled literal headlines, currency prices, offer snippets and CTAs with a caller-supplied prior snapshot. Omit previous for a baseline. On-demand only: no scheduling, stored history or proof of complete page changes. | $0.02 | Base | USDC | header | since 09-23 |
| POST | / | Qualify 2-10 distinct public business URLs against one ICP. Returns ranked existing-rule prospect scores, evidence and per-URL failure states. Fixed $0.10 per batch including partial successes; no charge if all fetches fail. Scores are heuristic, not calibrated win probabilities. | $0.10 | Base | USDC | header | since 09-21 |
| POST | / | Scores a public business URL for SDR agents, CRM enrichment, agency prospecting, and local-business lead generation: ICP fit, contactability, website trust friction, CTA issues, opportunity signals, evidence, confidence, and qualify/review/skip JSON. | $0.01 | Base | USDC | header | since 09-14 |

How the score works
What the score read on this service: status online, 100% uptime 30d, 380ms response p95, x402 compliance 14 of 14, $0.005 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 446 listings, this one among them: the same 446 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 ($0.23, 10 tx). Traction is a conservative undercount; first settlement seen 2026-09-04.
All measured facts
What it does
Pay-per-call APIs using USDC on Base. Fetch ($0.005 per completed request) turns public static HTML into bounded Markdown with source URLs, retrieval time and content hash. Optional section_id selects one named section; quality.section labels its scope. Supports bounded simple merged tables; no JavaScript, login, PDF, paywall or CAPTCHA bypass. Unsupported content fails before settlement. The catalog also includes prospect qualification and batches, listing formatting, ad/page checks, English creative OCR, campaign-link checks, email HTML preflight and on-demand offer comparisons. These are bounded evidence-based aids, not conversion, deliverability or compliance guarantees. Current schemas and limitations: https://signalforgestudios.com/x402/openapi.json
Signal Forge x402 Services 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.

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.

Values
* today so far, partial (UTC).
The uptime summary counts completed UTC days only. The strip, readouts and table retain today's partial reading.
Daily snapshot total, 30d: $0.24, peak $0.18 on 10-08. 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: 2026-09-30 to 2026-10-29 UTC; * today so far, partial (UTC). Daily snapshots store cents. A recorded $0.00 with settlements cannot distinguish exact zero from volume rounded away. Lost precision is unavailable here.
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.
