# agdata docs

The reference: how a call is paid, the routes, limits, response shapes, failures and refunds, Solana, MCP and discovery. The landing page has the short version.

## How a call is paid

Calls are paid in stablecoins: x402 on Base and Polygon (plus Solana on some routes) or MPP on Base.

Every route is one HTTP call. Send the JSON body with no payment: the answer is `402` with the quote for exactly that body, in the `PAYMENT-REQUIRED` header (x402) and a `WWW-Authenticate: Payment` challenge (MPP). Sign one and send the same body again with `PAYMENT-SIGNATURE` (x402) or `Authorization: Payment` (MPP). Either credential is accepted on either path.

Ask: POST the body to `/x402/<route>` or `/mpp/<route>`, with no payment.

Pay: sign the quote in stablecoins and repeat the same body with the payment.

Receive: `200` with the data and an `X-Agdata-Results-Delivered` header.

Refund: a short result is refunded on-chain for the part not delivered, in the background.

The quote is for the full call. A call that cannot be served is refused before anything settles, so nothing is charged.

## Routes

Each route is served on `/x402/<name>` and on `/mpp/<name>`, with the same body and the same price. The table lists the routes this server serves, with what each one returns; the response shape section explains the common fields.

## Limits and the quote

Routes that return lists take a `limit`, with a default and a maximum set by the server. The quote is for the full `limit`; what the call delivers is what is kept.

the unblocker, the screenshot, the transcript and the LinkedIn profile are single-item routes: no `limit`, one flat quote.

An unpaid call with a valid body always returns the quote, so you can read the price before you sign anything.

## Response shape

Most routes return the source's records in a fixed JSON shape. Instagram, YouTube, LinkedIn and Amazon can be served by more than one provider: each record keeps the provider's own fields and gains `source` and a `normalized` object with the same keys for every provider, `null` where a provider has no value.

Reddit and TikTok return compact records by default; `raw: true` returns the source's own records.

The unblocker returns one record: `url`, `finalUrl`, `statusCode`, `contentType`, `title`, `description`, `language`, `format`, `content` and `truncated`. `content` is Markdown unless you ask for `html` or `text`, and it is cut at 512 KiB.

## Failures and refunds

A call whose source returned nothing is never settled. The answer is `502` with `error: not_fetched` and `charged: false`, and the same payment can be used for a retry.

An unblocked page counts as delivered only when it is a real page: a block, challenge or error page is not charged.

A list with fewer results than the `limit` is settled for what came back, and the rest is refunded on-chain to the paying address.

Empty and placeholder answers are never cached.

A call the service cannot serve, or a payment that cannot be verified, is refused before it settles.

## Solana

Solana is offered on most routes, paid with x402. The routes table says which routes are not offered on Solana, because their runs take longer than a Solana payment window.

## MCP tools

`POST /mcp` is a remote MCP server (streamable HTTP, stateless): one tool per route, named like the route, with the route's own input schema. A tool call without payment returns the x402 quote in the result; the retry carries the signed payment in `_meta`, and the settlement comes back in the result.

## Feedback

`POST /feedback`, and the MCP tool `feedback`, are free and open, with no account. Send a message, and optionally a kind (bug, idea, praise or other), the route and a contact. Only the text and those fields are stored; no IP address and no wallet.

## Reliability and limits

There is no uptime SLA or uptime guarantee. Service and upstream availability are best-effort and can change.

A quote is shown before payment, and work starts only after settlement. A request refused before settlement is not charged; product-specific refund rules for partial results, orders and deals are described below.

Paid calls have no universal concurrency quota. Individual routes may have stricter caps: some routes allow only a few in-flight calls per target host or per route. Calls are cut off at their configured upstream deadline (normally 120 seconds, with shorter caps on some routes). For a short result, the missing portion is refunded; an undeliverable result is not charged.

Free GET docs, guides, pricing and discovery pages are limited to 120 requests per client IP per minute. They return RateLimit headers; a limit response is HTTP 429 with Retry-After. GET /health is a liveness check, not an uptime promise.

Failures are signalled with HTTP 402 when payment is required, 429 when a request is limited, 502 when a result cannot be delivered, and 503 when the service cannot accept work. Follow Retry-After when present. Report problems on the contact page at /contact.

## How it differs

API-key scraping services and data marketplaces commonly use accounts, keys, subscriptions, credits or monthly billing; agdata quotes each call before stablecoin payment and charges for delivered results.

## Discovery

`/openapi.json`: the OpenAPI 3.1 document, with the request schemas and the payment info.

`/.well-known/x402`: the x402 manifest.

`/agents.md`: the guide for agents (preferred), with the routes and the flow; `/llms.txt` is the same text for older tools.

`/pricing.md`: generated endpoint prices and quote behavior.

`/health`: the service's status.

Try the service without paying: send a GET request to a listed endpoint to receive its free `402` quote, then decide whether to sign and pay. The quote request does not start a paid delivery.

The free `GET /ask?query=...` route searches the product reference. When available, `POST /mcp/docs` is a free, read-only documentation server with search, section lookup, and endpoint schema tools.

## API versioning and deprecation policy

Versioned REST resources use `/v1`. Paid endpoint paths remain the documented `/x402/<name>` and `/mpp/<name>` forms; consult `/openapi.json` for the current contract. We aim to preserve compatible behavior within a version.

For a breaking change to a stable API surface, we will announce it in the documentation and provide `Deprecation` and `Sunset` response headers where applicable, with at least 90 days' notice before removal. Preview and upstream-dependent behavior can change sooner; check the live documentation.

## Authentication and payment

No API key, account, or subscription is required. Payment credentials authorize a specific quoted call and replace a reusable API key. Supported protocols on this service: x402 on Base and Polygon (plus Solana on some routes) or MPP on Base.

For x402, send a valid request without payment and read the HTTP 402 `PAYMENT-REQUIRED` challenge. Sign the offered amount and network, then retry the same request with `PAYMENT-SIGNATURE`. For MPP, the unpaid response includes `WWW-Authenticate: Payment`; retry with the matching `Authorization: Payment` credential. Never authorize a quote you have not checked.

A paid request delivers data only after settlement succeeds. The protocols accept their corresponding payment credential; use the route family's documented path and the exact body used to obtain the quote.

See the [API deprecation policy](/deprecation-policy) for route lifecycle commitments.

## Command-line tool

A small shell script (needs only sh and curl) lists the endpoints, prints the quote of a call and sends a call you have already signed. It never holds keys and never signs a payment.

`curl -fsSL https://agdata.shveik.dev/install.sh | sh
agdata help
agdata endpoints`

Commands: help, endpoints, docs, pricing, openapi, quote, call, health, version, update. Exit code 3 means a payment is required and the quote was printed. The installer puts the script in ~/.local/bin; its source is at /cli.
