# 1gateway

> 1gateway — Pay-per-call API gateway for AI agents (x402, USDC on Base, Monad or Solana). Data APIs normalized to English JSON; every data endpoint is paid per request with USDC via the x402 protocol (network eip155:8453 or eip155:143 or solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp). Pay with USDC on Base, Monad or Solana mainnet, same price; the 402 lists every option. No account or API key needed: request → HTTP 402 → pay → retry.

Current coverage: Korea data (Bank of Korea ECOS, real estate, trade, weather, holidays, company KYB), agent utilities (web read, document → Markdown incl. HWP/HWPX, metadata, domain, FX, time zones), Base onchain (token risk, flows, balances, DeFi yields), crypto markets (Hyperliquid perps, cross-venue funding, order books, stablecoins, spot ETF holdings, prices) and AI/agent tools (TTS, image, verdicts). The full paid list is /openapi.json.

## Document → Markdown

- [Document to Markdown: Korean HWP/HWPX to Markdown, plus web pages, PDF and DOCX](https://1gateway.dev/v1/convert/markdown?url=https://example.com/): $0.0027–$0.009 per call. Use when an agent must read a document as clean Markdown: web page, PDF, DOCX or Korean HWP/HWPX, tables kept. Input: url (http/https) via GET, or POST a file (multipart 'file', raw body, or JSON contentBase64+filename). Free-plan size cap → 413 before payment: HWP 48 KB, HWPX 100 KB XML. Output: JSON markdown, title, pages, sourceType, warnings. Price by detected type: HTML $0.0027, PDF/DOCX $0.0045, HWP/HWPX $0.009. Example: ?url=https://example.com/
  - `GET /v1/convert/markdown?url=<http(s) URL>[&type=]`
  - `POST /v1/convert/markdown` with multipart field `file`, a raw body (`?filename=report.hwp`), or JSON `{"url"| "contentBase64", "filename", "type"}`
  - Pricing (decided before payment from the detected type): Web page / HTML / plain text $0.0027; PDF, DOCX $0.0045; HWP, HWPX (Hancom) $0.009. For URLs the first 8 KB are fetched to detect the type; if the document changes to a pricier type before conversion you get 409 (not charged).
  - Size caps (Workers Paid): no per-format caps (Workers Paid); 10 MB per document. Over the cap → 413 `too_large_for_plan` before payment (not charged); for URLs without Content-Length that are larger than the 8 KB peek, the cap is checked after the fetch and before conversion (still not charged).
  - Limits: 10 MB per document, 3 redirects, 15 s fetch timeout, first 100 PDF pages, 200 HWP/HWPX sections. Public http(s) URLs only (private/loopback/link-local/metadata addresses are blocked). No OCR: scanned PDFs return 422. Password-protected documents return 422. HWP 3.x and legacy .doc are unsupported (415).
  - Output: `{markdown, title, pages?, sections?, sourceType, priceTier, bytes, chars, sourceUrl?, warnings}`. Tables become GFM tables; merged cells are repeated as empty cells.
  - Documents are processed in memory only; contents are not stored or logged.

## Useful ECOS tables (BOK-authored)

- 722Y001: BOK Base Rate and Deposit/Lending Rates (cycle M, item 0101000)
- 200Y101: Key Indicators (Annual) (cycle A)
- 101Y003: M2 by Instrument (Average, Seasonally Adjusted) (cycle M)

## Agent storage (/v1/agent/kv/*)

- The wallet that pays the call is the namespace: no API key. Pay with USDC on Base or Monad (a Solana payment is refused with 400, not charged). HTTP only (not an MCP tool).
- put $0.003 + $0.0005 per started KB of the value (quoted before payment; 64 KB max = $0.035), TTL 1-90 days (default 30); get / list / delete / touch (extend expiry, no re-send) $0.002. New puts pause with 503 (not charged) while total storage is at its global cap. Quota: 1,000 keys and 10 MB per wallet.
- The whole value of every write is checked by Llama Guard 3 (Workers AI). An unsafe value is not stored, and the call answers 200 {status: "refused"} and IS charged, because the check ran. Values are stored unencrypted at rest: no secrets.

## Agent file storage (/v1/files/*)

- POST a file to /v1/files/upload (raw body or multipart field file; ?visibility=private|public, ttl_days 1-7). The paying wallet (USDC on Base or Monad; Solana refused with 400, not charged) owns it. HTTP only (not an MCP tool).
- Accepted by content, not extension: png, jpeg, webp (≤ 5 MB), pdf (≤ 25 MB, ≤ 256 KB of text), UTF-8 text / json / csv / markdown (≤ 256 KB). HTML, SVG, scripts, executables, archives, audio and video → 415 before payment.
- Price quoted before payment: $0.005 + $0.001 per started MB + $0.0005 per started KB of text the safety model reads (0 for images). info / list / sign / visibility / delete $0.002.
- Every upload is screened on Workers AI (Llama Guard 3 over all text; a vision check on images and up to 3 images embedded in a PDF). An unsafe file is not stored, and the call answers 200 {status: "refused"} and IS charged, because the check ran.
- Downloads: https://1storage.dev/f/{id}. Public files need no signature; private files need a link from /v1/files/sign (expires 60 s-7 days). Deleting a file stops every link at once. Files are stored unencrypted at rest: no secrets. Abuse reports: contact@1gateway.dev

## Watches (free reads)

- GET https://1gateway.dev/v1/watch/{id}/events (header x-watch-secret): status, last check, last value, newest events; ?after=<seq>
- DELETE https://1gateway.dev/v1/watch/{id} (header x-watch-secret): cancel (not refunded)
- Webhooks: POST with header x-1gateway-signature t=<unix>,v1=<hex HMAC-SHA256 of `${t}.${body}`>, key = hex(SHA-256(secret)); retries after 1, 5 and 30 min. Best-effort, no SLA.
